Oil seals close or seal the spaces between stationary and moving components, preventing lubricants (oil or grease) from escaping, as well as offer protection from contaminants. Seals are offered in a variety of lip materials including Nitrile, Viton, and Silicone, just to name a few. We carry seals in both inch and metric sizes. Some of the manufacturers we carry are National, Chicago Rawhide, Garlock, John Mansville, Harwal, and TCM.
