Product Overview
An EPDM rubber washer and a Buna-N gasket may share similar dimensions while serving different material requirements. This custom offering allows the profile to follow the joint, with compound selection based on the actual temperature and substances present. Neither material should be treated as a universal substitute for the other.
Consider the operating cycle and the cleaning process. A seal may encounter one medium during use and another during maintenance, while heat can reach it through the mating surfaces. Select the formulation with those conditions in mind before finalizing hardness and thickness.
Measure the supported contact area and the closing gap to define the washer section. Install it flat without stretching the center opening, and use the assembly's intended closing arrangement. During servicing, inspect the ring and seat together for uneven compression, cuts, or material changes. Keep replacement variants identified by compound as well as dimensions so that a visually similar ring is not installed at a location with different exposure conditions.
- Material options
- EPDM. Custom formulation and color for the intended contact conditions.
- Hardness selection
- Rubber: 30–90 Shore A. Install it flat without stretching the center opening, and use the assembly's intended closing arrangement.
- Custom dimensions
- An EPDM rubber washer and a Buna-N gasket may share similar dimensions while serving different material requirements.
- Fit & assembly
- Measure the supported contact area and the closing gap to define the washer section.
- Use & inspection
- During servicing, inspect the ring and seat together for uneven compression, cuts, or material changes.

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.
