Custom made NBR/FKM/Rubber machine oil-proof seal gaskets

Custom machine seal gaskets need their compound selected for the specific oil and operating conditions at the joint. NBR and FKM are different options to consider. The material decision should include temperature, contact duration, and cleaning exposure before the gasket geometry is finalized.

Identify the supported contact surfaces and the available closing space. The outline should follow openings and locating features without leaving unsupported edges. A correct section allows the mating parts to close through their designed arrangement rather than requiring extra force to accommodate excess thickness.

Install the gasket cleanly and keep it aligned as the joint closes. During maintenance, inspect the removed component for swelling or persistent deformation and check whether the fluid or cleaning process has changed. Use a replacement with the specified formulation and profile rather than selecting solely by color or outside dimensions. If damage repeatedly occurs in the same location, examine the mating surface and clearance as part of the repair.

Material options

NBR / FKM. Custom formulation and color for the intended contact conditions.

Hardness selection

Rubber: 30–90 Shore A. A correct section allows the mating parts to close through their designed arrangement rather than requiring extra force to accommodate excess thickness.

Custom dimensions

The outline should follow openings and locating features without leaving unsupported edges.

Fit & assembly

Install the gasket cleanly and keep it aligned as the joint closes.

Use & inspection

During maintenance, inspect the removed component for swelling or persistent deformation and check whether the fluid or cleaning process has changed.
