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

Part number L18701625375B is a Polyurethane (AU/EU) Type B Loaded Lip Seal with a 1-5/8 in inside diameter, a 2 in outside diameter, and a height of 3/8 in. 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 (type B) Urethane.

Expect good resistance to impact and shock loading, extrusion under high pressure, and ozone. That behavior comes from the compound itself: Polyurethane (AU/EU) is specified for toughness that outperforms conventional rubber compounds and exceptional abrasion resistance. It should not be specified for service in hot water and steam or acids and bases.

Maintenance and OEM teams specify it across high-pressure fluid power, hydraulic cylinders, and construction machinery.

L18701625375B ships individually. Check the compound against your process media, pressure and temperature before committing to a design. Not finding the exact configuration you need? APG cross-references from prints, samples and competitor part numbers.
