4-1/2" ID X 5" OD X 1/4" HT

Part number L25004500250B is a Polyurethane (AU/EU) Type B Loaded Lip Seal built to a 4-1/2 in inside diameter, a 5 in outside diameter, and a height of 1/4 in. A loaded lip seal delivers low-friction dynamic sealing with strong resistance to pressure spikes. The catalog record notes: Loaded Lip Seal (type B) Urethane.

Expect good resistance to petroleum oils, ozone, and extrusion under high pressure. That behavior comes from the compound itself: Polyurethane (AU/EU) delivers outstanding extrusion resistance at elevated pressure and long wear life in dynamic reciprocating service. Verify compatibility before use with hot water and steam or acids and bases.

You will find this material specified across high-pressure fluid power, off-highway equipment, and mining and heavy equipment.

L25004500250B ships individually. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
