Product Overview
O-ring material selection for silicone rubber and Viton seals should account for the service medium and temperature as well as the joint geometry. Silicone and FKM options may be considered for different conditions, but rings with similar dimensions should remain identified by their intended formulation. A color or general rubber appearance is not a reliable basis for swapping materials during maintenance.
Compare the section size and installed diameter with the groove and mating clearance. Include the movement of the joint, if any, and the pressure direction that acts on the ring. The selected compound must work within that supported space rather than being stretched into an improvised seat.
Keep rings clean and separated by specification before assembly. Protect their surfaces from threads and sharp steps, and position them without twist. After removing a used ring, inspect the adjoining hardware for the cause of cuts or extrusion. If the operating fluid or cleaning process changes, revisit material suitability before continuing to use the previous ring solely because its dimensions remain correct.
- Material options
- FKM / Silicone. Custom formulation and color for the intended contact conditions.
- Hardness selection
- Rubber: 30–90 Shore A. Silicone: 20–80 Shore A. Include the movement of the joint, if any, and the pressure direction that acts on the ring.
- Custom dimensions
- Compare the section size and installed diameter with the groove and mating clearance.
- Fit & assembly
- The selected compound must work within that supported space rather than being stretched into an improvised seat.
- Use & inspection
- After removing a used ring, inspect the adjoining hardware for the cause of cuts or extrusion.
Photos illustrate structure or material only. Silicone and FKM options may be considered for different conditions, but rings with similar dimensions should remain identified by their intended formulation. 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.
