Product Overview
An EPDM rubber gasket seal should follow the joint's contact geometry without relying on flexibility to correct an uneven or damaged seat. Natural rubber and other compound options need to be assessed for their own suitability to the intended medium and exposure.
ETOL offers custom sizes, colors and material constructions. Define the profile and available assembled space alongside temperature, fluid contact and cleaning conditions. Keep the gasket supported across the intended sealing region rather than allowing an edge to bridge an open gap.
Clean the mating surfaces and position the rubber without stretching one area to align the rest. Secure the joint by its specified method and evaluate the required moisture-exclusion function in the complete arrangement. During maintenance, inspect both material condition and contact impressions. A localized deep mark can indicate a seat or alignment problem, while a general change in shape may require a material review. Address the cause before replacement and avoid adding fastening force to conceal a gap outside the gasket's designed contact.
- Material options
- EPDM / Natural rubber. Custom formulation and color for the intended contact conditions.
- Hardness selection
- Rubber: 30–90 Shore A. An EPDM rubber gasket seal should follow the joint's contact geometry without relying on flexibility to correct an uneven or damaged seat.
- Custom dimensions
- A localized deep mark can indicate a seat or alignment problem, while a general change in shape may require a material review.
- Fit & assembly
- Clean the mating surfaces and position the rubber without stretching one area to align the rest.
- Use & inspection
- During maintenance, inspect both material condition and contact impressions.
Photos illustrate structure or material only. The gasket outline needs continuous support across its sealing region so an edge does not bridge an open joint gap. 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.
