1-5/16" ID X 1-11/16" OD X 3/16" HT

Part number L18701312 is a Polyurethane (AU/EU) Standard Profile Loaded Lip Seal with a 1-5/16 inch inside diameter, a 1-11/16 inch outside diameter, and a height of 3/16 inch. A loaded lip seal combines a preloaded lip with pressure activation for consistent dynamic sealing. Supplementary detail from the product record: Loaded Lip Seal (standard) Urethane.

The material holds up against ozone, impact and shock loading, and abrasion and wear. That behavior comes from the compound itself: Polyurethane (AU/EU) is widely chosen for exceptional abrasion resistance and long wear life in dynamic reciprocating service. Applications involving acids and bases or hot water and steam call for a different compound.

You will find this material specified across high-pressure fluid power, hydraulic cylinders, and construction machinery.
