MOS-030-047-010-TC is a Buna-N (Nitrile) Double Lip with Spring Oil Seal measuring a 30 mm inside diameter, a 47 mm outside diameter, and a height of 10 mm. In service, this oil seal seals a rotating shaft against lubricant loss and contaminant ingress. Source specification: Rubber Covered OD, Double Lip W/ Spring.
This material stands up to water, propane and butane, and greases and lubricants. That behavior comes from the compound itself: Buna-N (Nitrile) is widely chosen for the most widely specified general-purpose sealing elastomer and low compression set under sustained load. It should not be specified for service in automotive brake fluid or polar solvents.
You will find this material specified across automotive, construction equipment, and general industrial maintenance.
Stocked as MOS-030-047-010-TC and sold individually. Review your operating media and conditions against this specification before installation. For a size or compound outside the standard catalog, APG can quote from a print or sample.
