Product Overview
For extruded rubber seal washers, the section geometry is a central part of the design. The material and profile need to suit the joint, with the finished dimensions establishing how the component sits between mating parts. Custom manufacture can adapt the shape to the required sealing path.
An oil-contact application should begin with the specific fluid, temperature, and duration of exposure. Select the compound for those conditions, then establish the section thickness and supported width. The production method does not by itself determine whether the finished washer will fit or remain suitable in service.
Check the complete component before installation, including its inner boundary and any transition around the perimeter. It should lie naturally in the seat without needing to be pulled into alignment. Bring the mating parts together using their intended locating features so that the rubber is not displaced sideways. During replacement, compare the working section with the required dimensions rather than relying only on the old part's outside size, which may have changed after sustained compression.
- Material options
- Rubber. Custom formulation and color for the intended contact conditions.
- Hardness selection
- Rubber: 30–90 Shore A. Select rubber compliance around the finished profile and space between the mating parts, verifying the intended closing position in the complete joint.
- Custom dimensions
- Bring the mating parts together using their intended locating features so that the rubber is not displaced sideways.
- Fit & assembly
- Check the complete component before installation, including its inner boundary and any transition around the perimeter.
- Use & inspection
- The production method does not by itself determine whether the finished washer will fit or remain suitable in service.

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.
