Product Overview
A Nitrile rubber gasket is a custom sealing part developed around a specified compound and joint outline. EPDM, HNBR, SBR and NBR represent different material families, so a gasket should be identified by its selected formulation as well as its dimensions. Matching shape is only one part of choosing a replacement.
ETOL can adapt the inner and outer geometry, hardness and color. Define the fluids and cleaning substances that will contact the gasket, together with the operating conditions relevant to the joint. Those details should guide the material choice before the final fit is evaluated.
When fitting a replacement, compare the sealing face and locating features with the original design rather than using a stretched old gasket as the sole pattern. Place the rubber without forcing narrow sections around protrusions. After the joint is assembled, check for displaced material at the visible edges. Keep different material versions separated in storage so an identical-looking spare does not introduce an unintended compound change during maintenance.
- Material options
- EPDM / HNBR / NBR / SBR. Custom formulation and color for the intended contact conditions.
- Hardness selection
- Rubber: 30–90 Shore A. Compare EPDM, HNBR, SBR and NBR grades in the same defined gasket geometry, assessing their response to the intended closing compression.
- Custom dimensions
- A Nitrile rubber gasket is a custom sealing part developed around a specified compound and joint outline.
- Fit & assembly
- After the joint is assembled, check for displaced material at the visible edges.
- Use & inspection
- Define the fluids and cleaning substances that will contact the gasket, together with the operating conditions relevant to the joint.

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.
