Product Overview
A flat rubber silicone washer should fit the joint's contact area through the relevant heating and cooling cycle. The adjoining components may change the available gap as their temperatures change, so the installed compression should be assessed beyond the initial assembly condition. The chosen silicone formulation needs to suit the actual medium and temperature at the washer.
Define the inner diameter, outside support, and thickness. Keep the washer from bridging an unsupported recess or pressing into the central passage. The mating faces should apply load evenly rather than relying on the rubber to correct a damaged surface.
Position the washer flat and centered before closing the joint. Protect it from twisting under rotating hardware. During maintenance, inspect for a permanent tilted shape or material pushed beyond the seat. If contact changes after heating, review the joint clearance and material selection together instead of automatically increasing washer thickness in a way that may create excessive compression at another operating state.
- Material options
- Silicone. Custom formulation and color for the intended contact conditions.
- Hardness selection
- Silicone: 20–80 Shore A. The adjoining components may change the available gap as their temperatures change, so the installed compression should be assessed beyond the initial assembly condition.
- Custom dimensions
- If contact changes after heating, review the joint clearance and material selection together instead of automatically increasing washer thickness in a way that may create excessive compression at another operating state.
- Fit & assembly
- Position the washer flat and centered before closing the joint.
- Use & inspection
- During maintenance, inspect for a permanent tilted shape or material pushed beyond the seat.

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.
