Product Overview
A thick silicone washer provides a deeper flexible section within a gasket joint, but additional thickness does not automatically improve sealing. The mating space, support faces, and fastening arrangement determine how that material compresses and whether it remains in its intended position.
Check the available gap alongside the inner opening and outside diameter. A thick ring may bulge outward or inward as the joint closes, particularly if part of its face is unsupported. The hard components should meet the intended assembly condition without forcing the washer into an uncontrolled flattened shape.
Evaluate water exclusion on the complete connection under the specified exposure rather than inferring a rating from the ring thickness. Observe the joint after fastening for displacement or uneven contact around the perimeter. On removal, inspect for a distorted cross-section, cuts, or evidence that the washer was pinched at one edge. If those patterns recur, review the seating geometry and compression arrangement before selecting an even thicker replacement.
- Material options
- Silicone. Custom formulation and color for the intended contact conditions.
- Hardness selection
- Silicone: 20–80 Shore A. A thick silicone washer provides a deeper flexible section within a gasket joint, but additional thickness does not automatically improve sealing.
- Custom dimensions
- Check the available gap alongside the inner opening and outside diameter.
- Fit & assembly
- The mating space, support faces, and fastening arrangement determine how that material compresses and whether it remains in its intended position.
- Use & inspection
- On removal, inspect for a distorted cross-section, cuts, or evidence that the washer was pinched at one edge.

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.
