3-1/4" ID X 3-7/8" OD X 5/16" HT

This loaded lip seal is supplied in Polyurethane (AU/EU) built to a 3-1/4 in inside diameter, a 3-7/8 in outside diameter, and a height of 5/16 in, catalogued under part number L31203250. It combines a preloaded lip with pressure activation for consistent dynamic sealing. This item is further identified as Loaded Lip Seal (standard) Urethane.

Polyurethane (AU/EU) is widely chosen for outstanding extrusion resistance at elevated pressure, very high tensile strength and load capacity. It resists ozone, petroleum oils, and impact and shock loading. Applications involving acids and bases or hot water and steam call for a different compound.

It sees regular use in hydraulic cylinders, high-pressure fluid power, and off-highway equipment.

This item is sold individually under part number L31203250. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
