Product Overview
A custom gasket washer is a preformed rubber component developed for a particular sealing interface. NBR and EPDM are available material choices, each selected for the actual exposure and joint requirements. The product is defined by its finished geometry and compound rather than treated as a liquid gasket-making material.
Specify the contact outline, openings, and working thickness around the mating parts. The seal should remain located during closure and receive the intended compression without being pushed into an unsupported space. The actual medium, temperature, and cleaning conditions guide the choice between material configurations.
During assembly, keep the sealing faces clean and the gasket flat. A similar-looking NBR or EPDM part should not be substituted solely because its outside dimensions match. Review the removed seal for an uneven contact pattern or localized cuts before fitting a replacement. Those observations can identify a seat or alignment issue that needs correction so the new component works in the interface for which it was developed.
- Material options
- EPDM / NBR. Custom formulation and color for the intended contact conditions.
- Hardness selection
- Rubber: 30–90 Shore A. The seal should remain located during closure and receive the intended compression without being pushed into an unsupported space.
- Custom dimensions
- Specify the contact outline, openings, and working thickness around the mating parts.
- Fit & assembly
- During assembly, keep the sealing faces clean and the gasket flat.
- Use & inspection
- Review the removed seal for an uneven contact pattern or localized cuts before fitting a replacement.

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.
