12 X 20 X 5 NITRILE OIL SEAL

Ordered as MOS-012-020-005-TC, this is a Buna-N (Nitrile) Double Lip with Spring Oil Seal measuring a 12 mm inside diameter, a 20 mm outside diameter, and a height of 5 mm. The oil seal retains lubricant inside a housing while excluding dirt, water and contamination from the bearing cavity. This item is further identified as Rubber Covered OD, Double Lip W/ Spring.

Expect good resistance to propane and butane, many alcohols, and petroleum-based oils. That behavior comes from the compound itself: Buna-N (Nitrile) offers an economical choice for high-volume maintenance programs, reliable performance in both static and dynamic service. It is not the right choice where automotive brake fluid or strong acids are present.

It sees regular use in construction equipment, hydraulic and pneumatic systems, and agricultural equipment.
