Product Overview
Thick rubber washers occupy more axial space than a thin separating layer, so their installed height needs to be considered alongside the fastener and adjoining components. The washer should receive its intended compression without preventing the joint from reaching the designed closing position. More rubber thickness is not automatically a remedy for an uneven mating surface.
Check the bore, outside support area, and clearance around the washer as it deforms. For a silicone version in a heated application, select the compound and assess the joint through its actual temperature cycle. Changes in surrounding dimensions can affect the available compression.
Place the washer squarely on its seat before tightening. Keep the load centered and inspect for material spreading into an unsupported region. During service, look for permanent tilt or a compressed section that differs around the circumference. Review the mating faces and load direction before replacement rather than adding another layer, which changes both the closing height and the contact arrangement beneath the hardware.
- Material options
- Silicone. Custom formulation and color for the intended contact conditions.
- Hardness selection
- Silicone: 20–80 Shore A. The washer should receive its intended compression without preventing the joint from reaching the designed closing position.
- Custom dimensions
- Check the bore, outside support area, and clearance around the washer as it deforms.
- Fit & assembly
- Thick rubber washers occupy more axial space than a thin separating layer, so their installed height needs to be considered alongside the fastener and adjoining components.
- Use & inspection
- Review the mating faces and load direction before replacement rather than adding another layer, which changes both the closing height and the contact arrangement beneath the hardware.

Ordering this custom component
Can the shape be adjusted to my mating parts?
Yes. Show the receiving opening, contact surfaces and clearance limits. We can review the dimensions and retaining features around the intended fit.
Which details should be agreed before tooling?
Agree the critical dimensions, material, hardness, visible surfaces and sample requirements. Explain how the part is installed and which interfaces control its function.
Can a sample help define the replacement?
A sample can help explain the structure. Compare it with the assembly because wear, swelling or compression may have changed its original dimensions.
How is the quotation for this part determined?
The material, part geometry, tooling, quantity and finishing affect the quotation. Include the intended batch size and delivery destination when describing your requirements.
