50 X 72 X 8 NITRILE OIL SEAL

This oil seal is supplied in Buna-N (Nitrile) with a 50 mm inside diameter, a 72 mm outside diameter, and a height of 8 mm, catalogued under part number MOS-050-072-008-SC. It uses a garter spring to maintain constant lip load against the shaft. This item is further identified as Rubber Covered OD, Single Lip W/ Spring.

It resists petroleum-based oils, propane and butane, and greases and lubricants. That behavior comes from the compound itself: Buna-N (Nitrile) is valued for the most widely specified general-purpose sealing elastomer and an economical choice for high-volume maintenance programs. It should not be specified for service in ozone and direct sunlight or polar solvents.

Maintenance and OEM teams specify it across automotive, general industrial maintenance, and hydraulic and pneumatic systems.

Stocked as MOS-050-072-008-SC and sold individually. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. For a size or compound outside the standard catalog, APG can quote from a print or sample.
