50 X 72 X 12 NITRILE OIL SEAL

MOS-050-072-012-TC is a Buna-N (Nitrile) Double Lip with Spring Oil Seal built to a 50 mm inside diameter, a 72 mm outside diameter, and a height of 12 mm. In service, this oil seal seals a rotating shaft against lubricant loss and contaminant ingress. The catalog record notes: Rubber Covered OD, Double Lip W/ Spring.

It resists hydraulic fluids, water, and propane and butane. That behavior comes from the compound itself: Buna-N (Nitrile) is specified for the most widely specified general-purpose sealing elastomer, reliable performance in both static and dynamic service. It is not the right choice where automotive brake fluid or ketones are present.

You will find this material specified across general industrial maintenance, automotive, and fluid power.

MOS-050-072-012-TC ships individually. Application requirements vary, so validate compatibility with your process conditions prior to installation. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
