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

APG stocks the L25004750, a Polyurethane (AU/EU) Standard Profile Loaded Lip Seal with a 4-3/4 inch inside diameter, a 5-1/4 inch outside diameter, and a height of 1/4 inch. A loaded lip seal uses a flexible sealing lip energized by system pressure to hold a tight seal on a moving rod or piston. Additional detail on this item: Loaded Lip Seal (standard) Urethane.

The material holds up against impact and shock loading, extrusion under high pressure, and petroleum oils. That behavior comes from the compound itself: Polyurethane (AU/EU) is valued for long wear life in dynamic reciprocating service, very high tensile strength and load capacity. Applications involving prolonged humidity at elevated temperature or acids and bases call for a different compound.

Maintenance and OEM teams specify it across construction machinery, hydraulic cylinders, and mining and heavy equipment.
