Product Overview
A non-standard silicone rubber seal ring is developed where a standard ring size or profile does not follow the intended joint. The custom dimensions should describe the actual sealing interface, including the space available for the rubber to sit and deform once the mating component is installed.
Begin with the groove or sealing face rather than an approximate spare ring. Identify the intended contact direction and any locating feature that controls the ring's position. The compound should suit the medium, temperature and cleaning exposure of the assembly.
Evaluate the custom part in a representative joint before adopting the configuration. Inspect how it seats around the full path and whether assembly displaces any portion from the intended area. If the old part has stretched or flattened, its free shape may no longer describe the original requirement. Keep the final replacement dimensions tied to the joint design, and handle new rings without pulling them over sharp hardware that could mark their sealing surfaces.
- Material options
- Silicone. Custom formulation and color for the intended contact conditions.
- Hardness selection
- Silicone: 20–80 Shore A. The custom dimensions should describe the actual sealing interface, including the space available for the rubber to sit and deform once the mating component is installed.

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.
