The rubber body measures 30 millimeters in diameter by 20 millimeters in height, while each M8 stud is 20 millimeters long. The complete mount is 60 millimeters high, and the rubber has a listed hardness of 60 Shore A. A distinctive construction detail is that the screws terminate at attached washers without penetrating the rubber, which the manufacturer says helps preserve dynamic stability under sideways forces.
That arrangement also makes the mounting hardware less likely to tear through the elastomer as the rubber flexes. Because the rubber can compress and rebound while the metal provides a secure connection, the mount can reduce the transfer of vibration, impact noise, and wear between an engine or machine and its base. Buyers still need to observe the equipment manufacturer's load and mounting requirements.
This set is a strong general recommendation for users with standard M8 mounting points who want more substantial isolation than flat washers. It is especially relevant for air compressors, water pumps, motors, heavy machinery, appliances, and electronic equipment. Verify the available clearance and hole pattern, position the mount correctly, and tighten the supplied nuts evenly for the most stable result.
Balanced Rubber and Metal Construction
The galvanized metal and soft rubber combination supports a firm attachment while allowing the center section to flex. This design is intended to reduce transmitted shock, vibration, and noise without relying on a thin pad alone.
Convenient for Standard M8 Mounts
The included nuts and washers simplify installation around compatible M8 holes. Even tightening helps the mount remain stable when the connected equipment is subject to lateral movement.

2. Treela 1.5 Inch Pads – Best Simple Rubber Isolation Pads
Treela 1.5 Inch Pads
One-point-five-inch outer diameter
Half-inch inner diameter
Ten-millimeter pad thickness
Sixty-five durometer rubber
Treela's set takes a different approach from stud-mounted isolators by providing thick rubber washers that fit around or beneath a suitable fastener. The eight pads have a 4.6 rating and offer a straightforward way to damp vibration in audio equipment, electronics, and lighter household or workshop applications.
Pros
- Simple drop-in installation
- Useful for audio equipment
- Wear-resistant rubber construction
- Eight pads included
- Multiple household applications
Cons
- No threaded mounting studs
- Not suitable for every heavy machine
We may earn a commission when you buy through this link, at no additional cost to you.
Each washer measures 1.5 inches in outer diameter, 0.5 inches in inner diameter, and 0.4 inches in thickness. The rubber is listed at 65 durometer, indicating a relatively firm material that should retain its shape better than very soft foam alternatives. The set can serve as isolation pads, foot pads, or general-purpose protective washers.
Their 10-millimeter thickness provides more separation than a conventional thin washer, while the central opening allows a compatible screw, bolt, or support post to pass through the pad. Installation requires no special tools beyond the hardware normally used to secure the equipment. The main benefit is flexibility: the same washer-style format can be adapted to several support arrangements.
This set is best for electronics, audio components, and lighter equipment where a simple pad is more appropriate than a tall load-bearing isolator. It may also work as a bumper or foot pad around furniture and other objects. For heavy engines, the absence of metal studs means the mounting arrangement must provide the structural strength independently, making these pads less appropriate for demanding industrial applications.
Useful for Audio and Electronics
The rubber washers are specifically described for absorbing shock and noise in audio and electronic equipment. Their central openings make them convenient beneath screws, posts, and other compatible supports.
Firm, Durable Rubber Construction
At 65 durometer, the material is described as wear resistant, tough, and suitable for long-term use. This makes the pads more versatile than disposable foam cushions while retaining a simple, adaptable format.

3. Yarssihha 40x40mm M8 Mounts – Best Premium Rubber Vibration Isolator Mounts
Yarssihha 40x40mm M8 Mounts
Forty by forty millimeters
M8 by twenty studs
Sixty Shore A rubber
Galvanized metal hardware
The larger member of the Yarssihha M8 range is built around a 40-by-40-millimeter rubber section, giving it more isolation material and a taller profile than the 30-by-20-millimeter version. It carries a 4.6 rating and is positioned for more demanding compressor, pump, motor, and machinery installations where additional separation may be beneficial.
Pros
- Larger rubber isolation section
- Improved vertical separation
- Stabilized side-force construction
- Complete mounting hardware
- Broad industrial compatibility
Cons
- Tallest listed stud mount
- Needs sufficient clearance

Each mount uses a 20-millimeter M8 stud and reaches an overall height of 80 millimeters. The rubber is specified at 60 Shore A, with a tolerance of plus or minus five Shore A units. Like the smaller model, it uses galvanized metal with screws die cast onto washers so the fasteners do not penetrate the flexible rubber. That arrangement is intended to maintain stability under dynamic and lateral forces.
The larger body can provide greater movement and shock control than a smaller cylindrical element, but it also changes the machine's installed height. That is an important distinction for equipment with fixed covers, belts, exhaust paths, wheel alignment, service clearances, or limited space beneath the base. The mount should be aligned with the equipment's existing M8 attachment points rather than used to create a new structural connection.
Choose this model when the application can accommodate an 80-millimeter overall height and the larger rubber body is justified by the vibration level or equipment weight. It is a sound premium-style option within this category, particularly for engines, compressors, generators, pumps, and other machinery. Check all clearances and tighten the supplied nuts evenly to maintain alignment.
More Rubber for Demanding Vibration
The 40-by-40-millimeter section is the clearest product-specific advantage over the more compact M8 option. It offers greater vertical separation and a larger flexible area for dampening recurring machine movement.
Designed for Lasting Connections
Keeping the studs from penetrating the rubber reduces the chance of a direct metal-to-rubber tear. Bonded washers and galvanized components support repeatable installation and resistance to everyday wear.

4. 25x25mm M6 Vibration Isolators – Best Compact Rubber Vibration Isolator Mounts
25x25mm M6 Vibration Isolators
Twenty-five-millimeter body
M6 by nineteen studs
Rubber and iron construction
Eight nuts included
These compact M6 isolators are suited to smaller equipment that produces enough vibration to justify a dedicated stud mount but lacks the space or load capacity for a larger unit. The four-piece set has a 4.6 rating and includes eight M6 nuts, making it practical for water pumps, welding machines, garage motors, electronic equipment, and fitness equipment.
Pros
- Compact mounting footprint
- Suitable for smaller equipment
- M6 hardware supplied
- Bonded rubber-metal construction
- Four-mount pack
Cons
- Smaller than M8 models
- Not intended for heavy loads
We may earn a commission when you buy through this link, at no additional cost to you.
The cylindrical rubber body measures 25 millimeters in diameter and 25 millimeters in height, with M6 studs measuring 19 millimeters. The construction combines rubber and iron bonded through a specialized process. The manufacturer describes this arrangement as wear resistant and suitable for handling machinery vibration, noise, and shock while remaining stable under lateral forces.
Installation is straightforward because the equipment can be aligned with the M6 studs and secured with the supplied nuts. A compact isolator is particularly useful beneath a small pump, a piece of fitness equipment, or another machine with a modest mounting footprint. Because the body is smaller than the 30- and 40-millimeter Yarssihha options, it should not be treated as a substitute for a mount approved for a much heavier machine.
This is the best budget choice in the guide for users with compatible M6 holes and a small-to-medium-sized machine. Measure the stud length against the thickness of the equipment's mounting foot before ordering, check the base surface for adequate support, and tighten the nuts evenly without compressing the rubber beyond its intended working shape.
Space-Saving Isolation for M6 Equipment
A 25-millimeter cylindrical body occupies less room than the larger M8 alternatives. It is a sensible choice when an equipment base has M6 holes and a smaller vibration-control footprint is required.
Bonded Rubber and Iron Build
The special bonding process is intended to resist wear and maintain a secure connection between the isolator and its metal hardware. That construction supports both shock absorption and stability during operation.

A rubber vibration isolator should be selected according to the equipment's hole pattern, stud or fastener dimensions, load, operating environment, and required isolation. None of those factors can be evaluated from the available data here. It would be especially risky to assume that the product uses the same M8, M6, or washer-style format as the neighboring selections.
The absence of supplied details does not establish that the item is unsuitable; it simply means that a confident recommendation would require information that is not present. Before buying, the live listing should be checked for the rubber dimensions, included hardware, overall height, load guidance, and the number of mounts in the package.
This entry is retained to preserve the complete ten-product comparison, but it should not be chosen over a fully specified option unless the live page confirms the required dimensions and application. The most responsible approach is to treat the product as an unverified alternative until its full technical information and compatibility can be confirmed.
Verify Before Selecting
Check the live product page for thread size, measurements, material, and included hardware. Compatibility should be established before ordering, not inferred from a similar product name.
No Performance Claims Available
Because no descriptive data or rating was supplied, no specific noise-reduction, load-bearing, or durability claim can be supported. The review therefore avoids assumptions about performance.

There is a meaningful difference between a flat isolation washer, a rubber foot, and a stud-mounted cylindrical isolator. Those formats cannot be substituted without checking hole diameter, fastener length, equipment weight, and base construction. The unknown information makes a definitive compatibility judgment impossible.
A buyer interested in this option should examine the current Amazon listing for a clear product title, dimensions, thread or fastener specifications, material description, quantity, and mounting instructions. If the page still lacks those details, contacting the seller may be the most reliable way to determine whether it fits the intended equipment.
This review is therefore informational rather than an endorsement. Among the products with complete supplied specifications, the 25x25mm M6 set, the 30x20mm M8 set, and the 40x40mm M8 set provide a more transparent basis for comparison. Use those documented options when immediate compatibility is the priority.
Match the Mount to the Equipment
Determine whether the equipment uses threaded studs, bolts, or a resting foot before considering a replacement. The fastener dimensions and attachment geometry must align with the mount design.
Prefer Transparent Specifications
A product that clearly states size, material, and included hardware is easier to evaluate. Seek that information before relying on general references to vibration isolation or equipment compatibility.

Rubber isolators perform through controlled elastic deformation, so the correct choice depends on the mass being supported and the amount of movement that must be absorbed. A compact pad may be appropriate for electronics, while a larger stud mount may be needed for a pump or motor. Without dimensions and a customer rating, those distinctions cannot be applied responsibly.
The live listing should be reviewed for package quantity, rubber dimensions, center-hole measurements, included fasteners, material, and any stated load limitations. It would also be useful to compare the product's shape with the existing mounting points on the intended machine. Do not use thread or diameter assumptions when the actual measurements are unknown.
This entry remains in the roundup for completeness, but the lack of supplied data makes it impossible to award an editorial advantage. Readers who value clear, immediately comparable specifications should favor one of the fully documented stud-mount sets or flat washers after confirming fit.
Look for Exact Mounting Dimensions
Outer diameter, inner diameter, thickness, and stud length determine whether a mount can physically attach. If these numbers are absent, obtain them before placing an order.
Check the Current Seller Listing
Product pages can change and may provide dimensions, imagery, and customer feedback not included in the source data. Verify the details directly rather than extrapolating from neighboring products.

A sound isolator selection should be based on the equipment's weight, attachment holes, operating motion, and installation space. Hardness also matters because a very soft rubber may deflect more than the surrounding structure can accommodate, while a firm material may offer less isolation. The absence of that information prevents a meaningful comparison.
Users should review the live page and look for a clear diagram or dimension list. The package quantity matters too, since machinery often requires a complete set of supports rather than one or two replacement pieces. Included nuts and washers should also be checked so the installation can be completed with the intended hardware.
This product is included because the roundup reflects the complete supplied ten-item set, but no verified advantage can be claimed. The documented M8 and M6 options provide a clearer path for buyers who already know the required thread size, while the flat Treela pads serve applications that call for a simple washer format.
Rubber Hardness Affects Deflection
Softer rubber generally permits more movement and absorbs lower-frequency vibration, while firmer rubber returns to shape more quickly. Match the material to the equipment's operating conditions.
Confirm the Full Mounting Kit
Check whether the package includes every mount needed for the machine along with nuts and washers. Missing hardware can prevent an otherwise simple installation from being completed.

8Pack M8 Rubber Studs
Twenty by thirty millimeters
M8 by twenty-three studs
Eight mount pack
Bonded dual-stud design
This eight-pack of M8 rubber stud mounts is a practical option when a complete machine needs several support points. It has a 4.3 customer rating and is listed for air compressors, water pumps, harvesters, garage motors, generators, diesel engines, gasoline engines, and heavy-duty mini-split heat pumps.
Pros
- Eight mounts in one package
- Dual threaded stud design
- High-durometer bonded rubber
- Anchoring accessories included
- Broad machinery compatibility
Cons
- Lower listed customer rating
- Shorter studs than competing M8 sets
We may earn a commission when you buy through this link, at no additional cost to you.
The cylindrical rubber body measures 20 millimeters in diameter by 30 millimeters in height. Each mount has an M8 stud measuring 23 millimeters in length, and the construction uses two terminated metal pieces bonded into high-durometer rubber. This dual-stud format provides an attachment point on both sides of the isolator, allowing it to sit between the equipment and a supporting structure.
The package includes anchoring accessories, and installation is based on aligning the device holes with the studs before fastening the nuts. The bonding arrangement is intended to provide durability and maintain the connection as the rubber buffers movement. Its eight-piece count is useful for machines that use more mounting points than a typical four-pack provides.
This set is a good candidate for compressors, generators, pumps, and similar equipment with compatible M8 holes. It is less suitable when mounting depth is extremely limited because the 23-millimeter stud is shorter than the 20-millimeter-plus studs on some competing products, although the available base and foot thicknesses ultimately determine the required length. The lower rating should also be considered alongside the attractive quantity and accessory package.
Eight Mounts Cover More Support Points
A complete eight-pack can simplify the installation of equipment with several feet. It also leaves replacement pieces available without requiring a second purchase.
Bonded Dual-Stud Construction
The two metal ends are terminated and bonded within the rubber, creating a secure central connection. This format is intended to withstand repeated flexing and sustained machinery operation.

10. 10PCS 192310GS Rubber Feet – Best Equipment-Specific Rubber Vibration Isolator Mounts
10PCS 192310GS Rubber Feet
One-ninety-two-three-one-zero-GS reference
Ten rubber feet included
Stainless steel washers included
Corrosion-resistant rubber
Unlike universal stud isolators, this set is designed around a specific equipment-foot reference and is intended as a direct replacement for several named compressor, generator, pressure-washer, and cabinet applications. It carries a 4.6 rating and includes ten rubber feet, making it attractive for repairs involving multiple feet or several compatible machines.
Pros
- Specific replacement part reference
- Broad named equipment compatibility
- Ten feet included
- Stainless steel washers supplied
- Washable maintenance design
Cons
- Less flexible than universal mounts
- Requires compatible equipment footprint
We may earn a commission when you buy through this link, at no additional cost to you.
The stated compatibility includes Coleman Powermate units, Sanborn 094-0026, E106661, Husky Fini D091007, RH-1606-8-A guitar cabinets, compressors, generators, and pressure washers. The product also references Briggs & Stratton part 192310GS. Because it serves specific parts and assemblies, buyers should compare the replacement number and the original foot shape rather than rely only on equipment type.
The feet are described as durable, corrosion-resistant rubber that absorbs shock, reduces noise, and helps protect floors and machinery. Stainless steel washers are included to support a non-slip installation. The feet can also be used on speaker cabinets, desks, radios, amplifiers, and furniture, including sofa cushions, although those broader uses do not alter the product's specific part identity.
This is the strongest choice for someone who recognizes the 192310GS reference or confirms that one of the listed replacement dimensions matches a worn original foot. It is less versatile than the M6 and M8 stud sets because the mounting geometry is predetermined. For the best outcome, compare the original foot's diameter, height, and attachment pattern before removing the old components.
Purpose-Built Replacement Compatibility
The specific replacement references and named equipment models make this set easier to match for targeted repairs. Verify the original part and the physical dimensions before purchasing.
Protective and Washable Construction
The rubber construction is intended to reduce floor wear, absorb shocks, and dampen equipment noise. Mild soap and water are recommended for cleaning the feet when maintenance is needed.

Buying Guide – How to Choose the Best Rubber Vibration Isolator Mounts
The right rubber vibration isolator mount depends on more than nominal diameter. Thread compatibility, load, rubber stiffness, isolation direction, mounting depth, and the equipment's operating environment should all influence the decision.
Thread and Hole Compatibility
Begin with the attachment points on the equipment. Stud-mounted products in this guide use M6 or M8 threads, while flat isolation pads have a 0.5-inch center opening. A mount cannot be installed correctly if its stud does not match the equipment's hole, nut, or factory foot, and a washer-style pad must have a center opening large enough for the intended fastener.
Confirm both thread diameter and stud length. The listed M6 model uses 19-millimeter studs, the 30x20mm and 40x40mm M8 sets use 20-millimeter studs, and the eight-pack M8 set uses 23-millimeter studs. Measure the combined depth of the equipment foot and base surface before ordering so the hardware can be tightened without bottoming out.
Equipment Weight and Support Load
The mount must carry the equipment without excessive permanent compression, rocking, or shear. Larger rubber sections generally provide more material and separation, but size alone does not establish a safe load rating. Check the equipment manufacturer's mounting guidance and any published load information for the specific isolator.
Choose a mount designed for the size and operating force of the machine rather than assuming four identical supports are automatically sufficient. Account for dynamic loads from motors, compressors, generators, and reciprocating equipment, because vibration can impose forces greater than the resting weight.
Rubber Hardness and Damping
Rubber hardness influences how the mount deflects, rebounds, and handles low-frequency movement. The Yarssihha M8 mounts are specified at 60 Shore A with a tolerance of plus or minus five units, while the Treela pads are listed at 65 durometer. These figures offer a useful comparison, although durometer and Shore A are not automatically interchangeable descriptions across every manufacturer.
Softer material can provide more movement and lower natural frequency, but it may allow excessive rocking. Firmer rubber tends to be more stable but may transmit more high-frequency energy. Select a hardness that suits the machine's weight, movement, and available mounting space, and follow the equipment maker's instructions when they specify a mount type.
Isolation Needs and Mount Style
Cylindrical stud mounts are well suited to machinery that needs a visible connection on both sides of an elastomer section. Flat washers are more convenient for audio and electronic equipment, while equipment-specific feet are useful when replacing original components. The correct format follows the attachment geometry and the amount of separation the installation requires.
A flat pad may be adequate when the goal is to separate a light component from a rigid shelf. A stud mount offers a clearer load path and greater isolation height for pumps, motors, and compressors. Purpose-built replacement feet are preferable when a known original part is missing and the replacement must preserve the machine's intended geometry.
Available Space and Total Height
Rubber isolators raise the supported item above its base, and that change can affect alignment, exhaust clearance, covers, belts, and service access. The 30x20mm Yarssihha mount has a listed overall height of 60 millimeters, while the 40x40mm version reaches 80 millimeters. The M6 set is described as compact, and the Treela washer has a thickness of 10 millimeters.
Measure the space under the equipment before choosing a taller model. Also inspect nearby walls, cabinets, pipes, and fasteners. The goal is adequate isolation without forcing the equipment into an unstable or inconvenient position.
Material and Environmental Durability
Look for a construction that is appropriate for the installation environment. The M8 Yarssihha mounts pair galvanized metal with rubber, the M6 set uses rubber and bonded iron, and the replacement feet set uses rubber with stainless steel washers. Galvanizing and stainless steel offer differing levels of corrosion resistance in workshop, garage, and outdoor settings.
Consider temperature, moisture, oil, and outdoor exposure when choosing a replacement. Inspect rubber for cracking, splitting, flattening, or separation from bonded hardware. Replace damaged mounts as a complete set when possible so all support points have similar stiffness and geometry.
Included Hardware and Installation Ease
Hardware completeness can determine whether installation is quick and secure. The Yarssihha sets include nuts and washers, the M6 set includes eight M6 nuts for four mounts, and the 192310GS set includes stainless steel washers. The Treela pads require a compatible fastener, while the 8Pack M8 set is described as including all anchoring accessories.
Even with supplied hardware, verify the fit before tightening. Position each mount squarely, ensure the equipment rests level, and tighten fasteners gradually and evenly. This reduces uneven compression and helps the machine remain stable during operation.
Verified Equipment Compatibility
General compatibility labels can be helpful, but exact part matching is stronger. The 192310GS feet specifically reference Briggs & Stratton 192310GS and several named machines, while the larger M8 sets list compressors, pumps, motors, heavy machinery, and other equipment. Confirm the mounting pattern and original part before relying on a model name.
For custom installations, compare the mount's dimensions, load expectations, and fastener length with the equipment's existing mounting points. If no specifications are available, the current listing or manufacturer should be consulted rather than making assumptions.
How to Use and Care for Your Rubber Vibration Isolator Mounts
Start by identifying every equipment support point and cleaning the mounting surfaces. Confirm that the stud or washer geometry matches the machine, then place the isolators in the correct locations. Check for adequate clearance beneath the equipment and ensure that no electrical, fuel, exhaust, or moving component can contact the new mount.
Align the equipment with the studs and lower it evenly onto the isolators. Install the supplied nuts and washers according to the equipment instructions, tightening gradually in a cross pattern when multiple fasteners are present. Avoid excessive torque, which can distort the base or compress the rubber beyond its working range. Confirm that the machine sits level and does not rock.
Inspect the mounts periodically for cracking, tearing, hardening, permanent flattening, or separation from the metal hardware. Replace any damaged component with the same size, thread, and rubber specification. Clean the 192310GS feet with mild soap and water, and keep other rubber mounts free of trapped oil and debris. Replace the full set when support points have aged unevenly.
Frequently Asked Questions
What are rubber vibration isolator mounts used for?
They are used to separate machinery or equipment from a rigid surface so that vibration, impact, and sound are reduced before reaching the supporting structure. Common applications include compressors, pumps, motors, generators, electronics, audio equipment, fitness equipment, and household appliances. The best mount depends on the machine's weight, attachment pattern, operating motion, and available space.
Are M6 and M8 vibration isolator mounts interchangeable?
No, not unless the equipment is designed to accept the different thread size. M6 mounts have smaller studs and generally suit smaller or lighter equipment, while M8 mounts are intended for applications requiring a larger connection. Changing the thread also affects hole size, nut compatibility, mounting depth, and the strength of the attachment, so the original equipment specifications should be checked.
How do I choose between flat rubber washers and stud-mounted isolators?
Flat washers are convenient for lighter equipment, audio components, and electronics that rest on a compatible screw or support post. Stud-mounted isolators provide a more defined connection between two surfaces and are often more appropriate for pumps, motors, compressors, and other machines. Consider load, required separation, attachment geometry, and whether the base can support the equipment independently.
Can rubber isolator mounts eliminate all vibration?
No mounting can guarantee complete vibration elimination because the rubber's stiffness, load, mounting structure, and the vibration frequency all influence performance. Properly sized isolators can substantially reduce transmitted movement and noise, particularly when the equipment is rigidly supported and installed level. Persistent vibration may also indicate an unbalanced component, loose hardware, or a mounting resonance.
How tight should the nuts on vibration isolator mounts be?
Tighten the nuts evenly until the equipment is securely mounted, but avoid crushing the rubber or stripping the studs. Follow the equipment maker's torque guidance when available. Since stud lengths and base thicknesses vary, confirm that the fastener has adequate engagement without bottoming out against the mounting surface.
Can I use the 192310GS rubber feet for other equipment?
They may work for compatible projects, but the primary value of this set is its compatibility with the referenced 192310GS replacement and the named compressor, generator, pressure-washer, and cabinet applications. Confirm the original foot's shape, dimensions, and attachment method before substituting it. Generic stud mounts offer more flexibility when the required pattern is not an exact match.
Why do vibration isolator mounts need different rubber sizes?
A larger rubber body generally provides greater vertical separation and more material through which vibration can be damped. It may also be better suited to heavier equipment, although actual load capacity should not be inferred from diameter alone. Smaller bodies are useful where space is limited, while flat washers are convenient for modest loads and simple installations.
How should worn rubber isolator mounts be replaced?
Replace a mount if the rubber is cracked, split, permanently flattened, separated from its metal parts, or noticeably softer than the remaining mounts. Match the original thread, stud length, rubber dimensions, hardness, and overall height. Replacing all support points together is preferable because mixed ages and compression levels can make the equipment sit unevenly.
Final Thoughts on Choosing the Best Rubber Vibration Isolator Mounts
The Yarssihha 30x20mm M8 mounts stand out as the most balanced general recommendation because they combine a reasonably compact profile, galvanized hardware, 60 Shore A rubber, and included mounting pieces. The 40x40mm version is the stronger choice when additional height and a larger isolation section are appropriate, while the 25x25mm M6 set serves smaller compatible equipment.
Prioritize the attachment system first, then consider load, rubber stiffness, total installed height, and the type of vibration. Flat Treela pads are useful for electronics and audio equipment, the eight-pack M8 mounts cover a larger number of support points, and the 192310GS set is valuable for verified replacement applications.

Before ordering, measure the existing holes, stud length, mounting depth, and space beneath the equipment, and follow the machine maker's isolation guidance where available. Prices, ratings, availability, and listing details can change, so check the current Amazon pages and seller information at the time of purchase to confirm compatibility.
