20 X 30 X 7 NITRILE OIL SEAL

Ordered as MOS-020-030-007-SC, this is a Buna-N (Nitrile) Single Case Oil Seal supplied with a 20 mm inside diameter, a 30 mm outside diameter, and a height of 7 mm. The oil seal protects bearings by holding grease or oil in and keeping abrasives out. Source specification: Rubber Covered OD, Single Lip W/ Spring.

Expect good resistance to petroleum-based oils, many alcohols, and propane and butane. That behavior comes from the compound itself: Buna-N (Nitrile) offers an economical choice for high-volume maintenance programs and low compression set under sustained load. It is not the right choice where strong acids or ozone and direct sunlight are present.

Common environments for this compound include agricultural equipment, construction equipment, and hydraulic and pneumatic systems.
