The L25003875375 is a Polyurethane (AU/EU) Deep Profile Loaded Lip Seal measuring a 3-3/4 in inside diameter, a 4-1/4 in outside diameter, and a height of 3/8 in. This loaded lip seal uses a flexible sealing lip energized by system pressure to hold a tight seal on a moving rod or piston. Source specification: Loaded Lip Seal (deep) Urethane.

Polyurethane (AU/EU) is specified here for outstanding extrusion resistance at elevated pressure and long wear life in dynamic reciprocating service. This material stands up to abrasion and wear, petroleum oils, and ozone. It is not the right choice where acids and bases or hot water and steam are present.

Common environments for this compound include press and forming equipment, hydraulic cylinders, and mining and heavy equipment.

This item is sold individually under part number L25003875375. Check the compound against your process media, pressure and temperature before committing to a design. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
