2-1/8" ID X 2-5/8" OD X 3/8" HT

L25002125375B is a Polyurethane (AU/EU) Type B Loaded Lip Seal measuring a 2-1/8 inch inside diameter, a 2-5/8 inch outside diameter, and a height of 3/8 inch. In service, this loaded lip seal delivers low-friction dynamic sealing with strong resistance to pressure spikes. This item is further identified as Loaded Lip Seal (type B) Urethane.

Expect good resistance to ozone, impact and shock loading, and petroleum oils. That behavior comes from the compound itself: Polyurethane (AU/EU) is valued for very high tensile strength and load capacity, long wear life in dynamic reciprocating service. Applications involving acids and bases or prolonged humidity at elevated temperature call for a different compound.

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

Stocked as L25002125375B and sold individually. Application requirements vary, so validate compatibility with your process conditions prior to installation. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
