Product Overview
An aging-resistant rubber gasket is developed around the conditions that gradually affect a seal during service. For a rectangular part, maintaining the long sides and corner geometry matters alongside the material choice. A gasket that has hardened, swollen or taken a permanent set may no longer follow the joint as intended, even when it remains in one piece.
ETOL offers custom dimensions, hardness and color with different rubber compounds available. Select the compound for the actual surroundings, including light exposure, nearby fluids and cleaning methods. The description of aging resistance does not establish a single service interval for every installation.
When replacing an older gasket, measure the mating recess or sealing face as well as the removed rubber. The used part may have stretched or changed thickness. Lay the replacement in its intended orientation and avoid pulling the long sides taut to make the corners reach. During maintenance, compare the entire perimeter for changes in firmness or contact, since one exposed side can age differently from a sheltered side.
- Material options
- Rubber. Custom formulation and color for the intended contact conditions.
- Hardness selection
- Rubber: 30–90 Shore A. The used part may have stretched or changed thickness.
- Custom dimensions
- ETOL offers custom dimensions, hardness and color with different rubber compounds available.
- Fit & assembly
- A gasket that has hardened, swollen or taken a permanent set may no longer follow the joint as intended, even when it remains in one piece.
- Use & inspection
- During maintenance, compare the entire perimeter for changes in firmness or contact, since one exposed side can age differently from a sheltered side.
Photos illustrate structure or material only. An exposed side of a rectangular seal can encounter different conditions from a sheltered corner. 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.
