Product Overview
Custom square seal gaskets can be produced with a profile suited to the mating assembly. NBR and FKM provide different material options, selected for the actual medium and temperature. A common square outline does not establish that the variants are interchangeable.
Define the side dimensions, corners, center opening, and thickness before selecting the finished component. The seat should support the rubber around its working path. Any locating holes or nearby features need to remain aligned without stretching the gasket during installation.
Fit the selected variant on clean surfaces and inspect the complete outline before closing the joint. Use the intended sequence so that the rubber is not dragged sideways. During servicing, keep compounds separated when their shapes and colors are similar. Check removed gaskets for swelling, cuts, or lasting deformation. Match the specified material and profile in the replacement rather than choosing whichever square ring appears closest to the used part's altered shape.
- Material options
- NBR / FKM. Custom formulation and color for the intended contact conditions.
- Hardness selection
- Rubber: 30–90 Shore A. Any locating holes or nearby features need to remain aligned without stretching the gasket during installation.
- Custom dimensions
- Define the side dimensions, corners, center opening, and thickness before selecting the finished component.
- Fit & assembly
- The seat should support the rubber around its working path.
- Use & inspection
- Fit the selected variant on clean surfaces and inspect the complete outline before closing 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.
