40 X 68 X 10 NITRILE OIL SEAL

APG stocks the MOS-040-068-010-SC, a Buna-N (Nitrile) Single Case Oil Seal measuring a 40 mm inside diameter, a 68 mm outside diameter, and a height of 10 mm. An oil seal 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.

This material stands up to greases and lubricants, propane and butane, and water. That behavior comes from the compound itself: Buna-N (Nitrile) is specified for low compression set under sustained load, strong abrasion and tear resistance. It should not be specified for service in automotive brake fluid or strong acids.

You will find this material specified across hydraulic and pneumatic systems, general industrial maintenance, and construction equipment.

MOS-040-068-010-SC ships individually. Check the compound against your process media, pressure and temperature before committing to a design. Not finding the exact configuration you need? APG cross-references from prints, samples and competitor part numbers.
