Product Overview
A custom rubber o-ring fits a defined sealing groove or joint using its inner diameter and circular section. EPDM, NBR, FKM, and silicone are material options for different conditions. The intended medium and temperature should guide the formulation, while the joint geometry determines the required dimensions and support.
Establish the groove and mating surfaces before selecting hardness. The ring should sit without being twisted or stretched into an unsuitable diameter, and the closing parts should apply the intended compression. Cleaning substances and maintenance exposure belong in the material assessment alongside the normal process medium. Place the ring on clean surfaces and protect it from sharp edges during assembly. Inspect the completed joint under its intended conditions rather than assigning a universal pressure or temperature capability from the material name. After disassembly, check the rubber's condition and preserve the exact section and formulation during replacement. A ring that fits the same outer space may still have a different working relationship with the groove.
- Material options
- EPDM / NBR / FKM / Silicone. Custom formulation and color for the intended contact conditions.
- Hardness selection
- Rubber: 30–90 Shore A. Silicone: 20–80 Shore A. The ring should sit without being twisted or stretched into an unsuitable diameter, and the closing parts should apply the intended compression.
- Custom dimensions
- A custom Rubber o-ring fits a defined sealing groove or joint using its inner diameter and circular section.
- Fit & assembly
- Place the ring on clean surfaces and protect it from sharp edges during assembly.
- Use & inspection
- Cleaning substances and maintenance exposure belong in the material assessment alongside the normal process medium.

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.
