Product Overview

A colored rubber washer can contribute to the appearance of an exposed joint as well as provide a flexible contact layer. With a thicker custom profile, more of the edge may remain visible between the mating components. Color, outline, and installed compression therefore influence the finished result together.

The visible width should be considered after the assembly closes. Rubber displaced beyond the contact land can make the edge look uneven and may indicate that the compression space is unsuitable. The opening and outer dimensions need to fit the seat without forcing material into adjacent clearances.

Select the compound for the actual service environment before finalizing the color. Pigmentation does not identify the material or establish its suitability for a particular fluid. Fit the washer evenly so the exposed edge remains consistent around the joint. During cleaning, avoid pulling at a projecting section. If the edge becomes distorted, examine the mating faces and clamping arrangement rather than trimming away rubber that may be part of the intended contact geometry.

Material options: Rubber. Custom formulation and color for the intended contact conditions.
Hardness selection: Rubber: 30–90 Shore A. A colored rubber washer can contribute to the appearance of an exposed joint as well as provide a flexible contact layer.
Custom dimensions: The opening and outer dimensions need to fit the seat without forcing material into adjacent clearances.
Fit & assembly: If the edge becomes distorted, examine the mating faces and clamping arrangement rather than trimming away rubber that may be part of the intended contact geometry.
Use & inspection: Select the compound for the actual service environment before finalizing the color.

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.
