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

Part number L31205125 is a Polyurethane (AU/EU) Standard Profile Loaded Lip Seal measuring a 5-1/8 inch inside diameter, a 5-3/4 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. The catalog record notes: Loaded Lip Seal (standard) Urethane.

Expect good resistance to abrasion and wear, petroleum oils, and impact and shock loading. That behavior comes from the compound itself: Polyurethane (AU/EU) is specified for long wear life in dynamic reciprocating service and outstanding extrusion resistance at elevated pressure. Applications involving ketones or acids and bases call for a different compound.

Maintenance and OEM teams specify it across off-highway equipment, high-pressure fluid power, and hydraulic cylinders.
