1-5/16" ID X 1-11/16" OD X 5/16" HT

This loaded lip seal is supplied in Polyurethane (AU/EU) supplied with a 1-5/16 inch inside diameter, a 1-11/16 inch outside diameter, and a height of 5/16 inch, catalogued under part number L18701312312B. It delivers low-friction dynamic sealing with strong resistance to pressure spikes. Supplementary detail from the product record: Loaded Lip Seal (type B) Urethane.

Expect good resistance to impact and shock loading, extrusion under high pressure, and petroleum oils. That behavior comes from the compound itself: Polyurethane (AU/EU) is known for exceptional abrasion resistance and outstanding extrusion resistance at elevated pressure. Verify compatibility before use with acids and bases or prolonged humidity at elevated temperature.

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

Stocked as L18701312312B and sold individually. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. 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.
