Product Overview
A rubber gasket sealing washer provides a compliant ring at a joint, with cushioning and sealing requirements considered together. Its custom dimensions and compound should suit the mating faces and the space available when the assembly closes. Color and material options can be selected for the intended environment.
Determine the working thickness rather than judging the washer only before compression. A ring that cushions softly may allow more movement than the joint is intended to have, while excessive tightening can push rubber beyond its supporting face. The inner opening and outer diameter should keep the contact region properly supported.
Fit the washer flat and prevent it from shifting as the mating parts meet. Keep debris off the faces so pressure is not concentrated around a particle. Evaluate any required seal with the completed joint under its operating conditions. During disassembly, inspect the compression pattern for evidence of uneven seating. Match the replacement to the intended section and compound, including its thickness, rather than selecting any ring that clears the same central fastener or shaft.
- Material options
- Rubber. Custom formulation and color for the intended contact conditions.
- Hardness selection
- Rubber: 30–90 Shore A. A ring that cushions softly may allow more movement than the joint is intended to have, while excessive tightening can push rubber beyond its supporting face.
- Custom dimensions
- The inner opening and outer diameter should keep the contact region properly supported.
- Fit & assembly
- Fit the washer flat and prevent it from shifting as the mating parts meet.
- Use & inspection
- Match the replacement to the intended section and compound, including its thickness, rather than selecting any ring that clears the same central fastener or shaft.

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.
