Custom made rubber oil seal parts/rubber washer/O-ring

Rubber oil seal parts should be specified for the actual contact in the machine joint. A washer closing between faces and an O-ring in a supported groove are different from a seal working against a moving component. Define the format and movement before choosing the rubber compound and dimensions.

Select the formulation for the oil, additives, temperature, and cleaning exposure that reach the part. Check the support around the section and the gap in the direction of pressure. The fit should preserve the intended passage or movement without allowing the rubber to escape into an adjacent clearance.

Install on clean surfaces and protect the contact region from sharp assembly features. Assess the completed joint under its relevant operating conditions. During service, inspect the old part for damage that identifies a mating surface or alignment issue. A material substitution should not be used as a general response to every leak, since an unsupported edge or damaged face may require correction in the surrounding hardware.
