Product Overview
A colored rubber washer can identify a custom version within an assembly, while its dimensions and compound determine the actual contact. Keep color associated with the complete specification rather than treating it as a universal guide to material or size. Two visually similar washers may need different compression in their respective joints.
Match the inner diameter, outer support area, and thickness to the mating faces. Select the formulation for the actual medium and temperature. The washer should remain clear of passages and fully supported where the closing force acts.
Place the selected version flat on clean surfaces and keep it centered during fastening. Inspect for twisting or an edge pushed into an unsupported gap. During maintenance, compare the removed part with its intended specification before selecting a replacement from a mixed group. A changed color convention or similar outside appearance should not conceal a difference in section that alters the joint's closing position or sealing contact.
- Material options
- Rubber. Custom formulation and color for the intended contact conditions.
- Hardness selection
- Rubber: 30–90 Shore A. The washer should remain clear of passages and fully supported where the closing force acts.
- Custom dimensions
- A changed color convention or similar outside appearance should not conceal a difference in section that alters the joint's closing position or sealing contact.
- Fit & assembly
- Place the selected version flat on clean surfaces and keep it centered during fastening.
- Use & inspection
- During maintenance, compare the removed part with its intended specification before selecting a replacement from a mixed group.

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.
