Product Overview
A thick gasket washer can provide a substantial rubber section around a matching joint. For a Buna-N configuration, the compound and geometry should be selected for the actual medium and operating conditions. A thick section still needs the correct support and compression; extra material does not automatically create a more reliable seal.
Custom dimensions can follow the bore, outer footprint and installed height required by the assembly. Check whether the mating surfaces support the washer across its intended contact area, especially where a flange or fitting leaves a clearance beside the rubber. Choose color separately from the material identification.
Evaluate any water-sealing function in the finished joint under the required conditions. During fitting, keep the washer centered and inspect for an edge that becomes trapped or pushed into the opening. If the used part is distorted, compare the intended design dimensions before selecting a replacement. Correct the seating geometry or assembly method where necessary so the next washer is not subjected to the same uneven contact.
- Material options
- Rubber. Custom formulation and color for the intended contact conditions.
- Hardness selection
- Rubber: 30–90 Shore A. A thick section still needs the correct support and compression; extra material does not automatically create a more reliable seal.
- Custom dimensions
- Custom dimensions can follow the bore, outer footprint and installed height required by the assembly.
- Fit & assembly
- Correct the seating geometry or assembly method where necessary so the next washer is not subjected to the same uneven contact.
- Use & inspection
- During fitting, keep the washer centered and inspect for an edge that becomes trapped or pushed into the opening.

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.
