28 X 38 X 7 FLUOROELASTOMER OIL SEAL

APG stocks the MOSV-028-038-007-SC, a Viton® (FKM) Single Case Oil Seal with a 28 mm inside diameter, a 38 mm outside diameter, and a height of 7 mm. An oil seal seals a rotating shaft against lubricant loss and contaminant ingress. The catalog record notes: Rubber Covered OD, Single Lip W/ Spring.

The material holds up against many acids, petroleum oils and fuels, and aggressive chemicals. That behavior comes from the compound itself: Viton® (FKM) is widely chosen for the industry benchmark where nitrile reaches its thermal limit, excellent resistance to compression set and permeation. It is not the right choice where ketones and esters or low-molecular-weight organic acids are present.

You will find this material specified across high-temperature process equipment, aerospace, and oil and gas.

Stocked as MOSV-028-038-007-SC and sold 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.
