Product Overview

A High Temperature Resistant Rubber Washer should be selected around the conditions at the joint where it is installed. The compound determines which combination of heat, fluids and exposure duration the washer can accommodate, while its dimensions establish the contact within the assembly.

Rubber washers and gaskets can be cut or molded in different forms, with materials including NBR, SBR, CR and EPDM used for selected applications. Choose the particular formulation for the actual duty rather than treating every rubber option as having the same thermal or chemical behavior.

Check the mating faces, inside opening and assembled space before selecting the washer thickness. Local projections or incomplete support can concentrate compression and affect contact as the joint operates. Fit the washer flat and use the assembly's specified fastening condition.

Evaluate the completed joint through its intended operating conditions. For servicing, follow the prescribed cooling and release procedure before opening it. Inspect the removed washer for hardening, cuts or a permanent uneven impression, and examine the matching face for the cause. A replacement should address both the material requirement and the geometry of the contact rather than only matching the old washer's outside diameter.

Material options: Rubber. Custom formulation and color for the intended contact conditions.
Hardness selection: Rubber: 30–90 Shore A. Local projections or incomplete support can concentrate compression and affect contact as the joint operates.
Custom dimensions: Check the mating faces, inside opening and assembled space before selecting the washer thickness.
Fit & assembly: Fit the washer flat and use the assembly's specified fastening condition.
Use & inspection: Inspect the removed washer for hardening, cuts or a permanent uneven impression, and examine the matching face for the cause.

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.
