Product Overview
A silicone gasket with a D-shape ring profile needs a defined orientation in its mating interface. Whether the D-shaped feature belongs to the ring outline or its section, that feature should match the intended seat rather than be forced into a conventional round arrangement.
ETOL supports custom size, color and material construction. Identify the locating face and curved region before selecting the profile. Compare the complete interface, including the assembled space and contact direction, so the shape remains stable when the joint is closed.
Place the ring without twisting and inspect its orientation around the full contact path. Keep debris out of the seat and follow the joint's specified assembly condition. Evaluate the required function with the selected compound under the intended exposure. During disassembly, inspect for an uneven impression that may indicate rolling or a reversed fit. Correct the locating geometry or installation path before replacement, and do not stretch a distorted ring back into place merely because its overall size still appears close to the opening.
- Material options
- Silicone. Custom formulation and color for the intended contact conditions.
- Hardness selection
- Silicone: 20–80 Shore A. Coordinate firmness with contact direction and the assembled gap, checking that the silicone profile remains located as compression develops.
- Custom dimensions
- Whether the D-shaped feature belongs to the ring outline or its section, that feature should match the intended seat rather than be forced into a conventional round arrangement.
- Fit & assembly
- Keep debris out of the seat and follow the joint's specified assembly condition.
- Use & inspection
- During disassembly, inspect for an uneven impression that may indicate rolling or a reversed fit.

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.
