Product Overview
A square thick washer for an exhaust-system assembly must be selected for the specific location and its actual contact conditions. The custom outline and section can follow the mating components, while the rubber formulation needs to suit the temperature and substances at that position. A general exhaust application does not make a rubber washer suitable for every hot-gas joint.
Identify whether the component belongs at a support, an external interface, or another defined position in the assembly. That role determines the required material and the way the washer is loaded. Preserve the specified use rather than substituting the part into a different connection based only on its shape.
Compare side lengths, center opening, corner geometry, and thickness with the intended seat. The washer should remain supported as the assembly closes, without obstructing fastener engagement or adjacent hardware. Use the equipment's prescribed installation procedure and operating limits.
During maintenance, inspect the contact faces and look for recurring deformation in the rubber. A replacement needs the correct formulation and complete profile. Do not compensate for an unsuitable material or damaged mating surface by adding more thickness, since that changes the assembled geometry without establishing suitability for the service.
- Material options
- Rubber. Custom formulation and color for the intended contact conditions.
- Hardness selection
- Rubber: 30–90 Shore A. That role determines the required material and the way the washer is loaded.
- Custom dimensions
- The custom outline and section can follow the mating components, while the rubber formulation needs to suit the temperature and substances at that position.
- Fit & assembly
- Identify whether the component belongs at a support, an external interface, or another defined position in the assembly.
- Use & inspection
- Do not compensate for an unsuitable material or damaged mating surface by adding more thickness, since that changes the assembled geometry without establishing suitability for the 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.
