The sealing lip is always made of a rubber or synthetic material. For oil seals with a rubber outer case (R, RST, GR, GRST), the rubber quality of the sealing lip and the outer case are the same.

Global O-Ring and Seal’s oil seal part numbers are designed to describe the seal size, style, and material composition. When searching for oil seals via our online store, you will not only be presented with your selection but with comparable oil seals of the same dimensions. There are often viable style substitutions that are functionally compatible but with additional features. With over 50,000 unique oil seals in our database, you can cross-reference 215,000 part numbers of OEMs and Manufacturers. In the Search Bar above, simply type the OEM/manufacturer part number alone (no need to type the name), and the oil seals matching that part number will be displayed.

Rubber oil seals have to perform in extreme conditions. Therefore, we accommodate all relevant conditions (mechanical and thermo-chemical phase) to maintain the integrity of the rubber oil seal in these circumstances.
