Product Overview
EPDM rubber flat gaskets need a compound and profile selected for the specific joint. A silicone washer may be another design option, but the two materials should not be treated as interchangeable simply because both can form a ring. The medium, temperature and cleaning exposure determine the relevant material requirements.
Check the mating faces and available compression for the actual section being used. The gasket outline must leave required openings clear while providing supported contact around them. A general waterproof label does not establish a performance rating for every assembly using that profile.
Fit the selected component flat against clean faces without stretching it into alignment. Evaluate the complete joint for its intended duty. During replacement, preserve the chosen formulation and dimensions rather than matching only color or outside size. If the original part shows uneven damage, inspect the receiving surfaces before refitting so a different material is not used to mask an unresolved gap, burr or misalignment in the assembly.
- Material options
- EPDM / Silicone. Custom formulation and color for the intended contact conditions.
- Hardness selection
- Rubber: 30–90 Shore A. Silicone: 20–80 Shore A. Check the mating faces and available compression for the actual section being used.
- Custom dimensions
- The gasket outline must leave required openings clear while providing supported contact around them.
- Fit & assembly
- Fit the selected component flat against clean faces without stretching it into alignment.
- Use & inspection
- If the original part shows uneven damage, inspect the receiving surfaces before refitting so a different material is not used to mask an unresolved gap, burr or misalignment in the assembly.

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.
