APG stocks the L18700500312B, a Polyurethane (AU/EU) Type B Loaded Lip Seal with a 1/2 inch inside diameter, a 7/8 inch outside diameter, and a height of 5/16 inch. A loaded lip seal maintains contact with the sealing surface even as clearances change under load. Supplementary detail from the product record: Loaded Lip Seal (type B) Urethane.

Polyurethane (AU/EU) is widely chosen for outstanding extrusion resistance at elevated pressure and long wear life in dynamic reciprocating service. Expect good resistance to petroleum oils, extrusion under high pressure, and abrasion and wear. Applications involving ketones or acids and bases call for a different compound.

You will find this material specified across construction machinery, off-highway equipment, and high-pressure fluid power.

Stocked as L18700500312B and sold individually. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
