Product Overview
A rubber cushion gasket introduces a flexible contact between components, while a sealing washer must also establish the required barrier at its mating surfaces. These functions can share a molded part, but they should be evaluated separately. A cushioning feel does not demonstrate that a continuous seal exists around the joint.
Define the contact area, available compression, and the load applied through the surrounding hardware. The rubber should remain supported rather than being squeezed into an open gap. The formulation needs to suit any medium or cleaning exposure at the interface as well as the mechanical contact.
Assess the assembled joint for both its movement or cushioning behavior and its required sealing function. Watch for displacement as the components close and for an unintended hard contact that bypasses the flexible layer. During inspection, compare the resting profile and contact pattern with the intended condition. A lasting change can affect clearance or compression even when the part has no obvious tear, so replacement decisions should consider more than the visible outer edge.
- Material options
- Silicone. Custom formulation and color for the intended contact conditions.
- Hardness selection
- Silicone: 20–80 Shore A. A rubber cushion gasket introduces a flexible contact between components, while a sealing washer must also establish the required barrier at its mating surfaces.
- Custom dimensions
- Watch for displacement as the components close and for an unintended hard contact that bypasses the flexible layer.
- Fit & assembly
- Assess the assembled joint for both its movement or cushioning behavior and its required sealing function.
- Use & inspection
- The formulation needs to suit any medium or cleaning exposure at the interface as well as the mechanical contact.
Photos illustrate structure or material only. A cushioning feel does not demonstrate that a continuous seal exists around the joint. ETOL directly manufactures custom-shaped silicone and rubber parts to your requirements.

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.
