Product Overview

Custom rubber flat gaskets for machine joints should be developed around the mating outline and the features that locate them during assembly. NBR and FKM material versions need selection according to the actual medium and temperature. The gasket should sit on its intended contact path before the cover or adjoining part is fastened.

Check how the part remains positioned during closing. A large unsupported area or narrow connecting section can move as the cover approaches. Verify alignment at openings and corners instead of assuming that fastening will pull the gasket into the correct place.

The joint should compress the working region without pushing rubber into adjacent passages. Clean the mating faces before fitting and inspect the gasket for a fold while access is still available. On service removal, look for displaced sections and local contact marks that reveal uneven support. Replace damage with the correct contour and thickness. A thicker flat gasket should not be used as a general remedy for a cover that is misaligned or has an obstructed seat.

Material options
NBR / FKM. Custom formulation and color for the intended contact conditions.
Hardness selection
Rubber: 30–90 Shore A. The joint should compress the working region without pushing rubber into adjacent passages.
Custom dimensions
Custom rubber flat gaskets for machine joints should be developed around the mating outline and the features that locate them during assembly.
Fit & assembly
Verify alignment at openings and corners instead of assuming that fastening will pull the gasket into the correct place.
Use & inspection
Clean the mating faces before fitting and inspect the gasket for a fold while access is still available.

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.
