Product Overview
A custom rectangular flat FKM/FPM rubber gasket seals between mating surfaces that support its defined outline. The outer dimensions, inner opening, and thickness should be coordinated with the available contact band. The corners and straight sections need to remain located as the joint closes.
A flat gasket should not be stretched to make its corners reach a mismatched seat, because this can change its thickness and contact along the sides. Clean the mating faces and place the part without folds or trapped particles. The fastening arrangement should apply the compression intended by the joint design rather than rely on extra tightening to correct a dimensional mismatch. After disassembly, inspect the contact pattern around the full rectangle, including less visible sections near hardware. Replacement should preserve the exact thickness and material configuration as well as length and width, so the original supported sealing relationship is restored. Preserve the rectangular corner radii when comparing replacement profiles.
- Material options
- FKM. Custom formulation and color for the intended contact conditions.
- Hardness selection
- Rubber: 30–90 Shore A. The fastening arrangement should apply the compression intended by the joint design rather than rely on extra tightening to correct a dimensional mismatch.
- Custom dimensions
- The outer dimensions, inner opening, and thickness should be coordinated with the available contact band.
- Fit & assembly
- A custom rectangular flat FKM/FPM Rubber Gasket seals between mating surfaces that support its defined outline.
- Use & inspection
- Replacement should preserve the exact thickness and material configuration as well as length and width, so the original supported sealing relationship is restored.
Photos illustrate structure or material only. The straight sides and corner radii of a rectangular FKM gasket need one continuous supported contact band. 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.
