2-1/4" ID X 2-7/8" OD X 3/8" HT

This loaded lip seal is supplied in Polyurethane (AU/EU) measuring a 2-1/4 inch inside diameter, a 2-7/8 inch outside diameter, and a height of 3/8 inch, catalogued under part number L31202250375B. It maintains contact with the sealing surface even as clearances change under load. The catalog record notes: Loaded Lip Seal (type B) Urethane.

It resists petroleum oils, extrusion under high pressure, and ozone. That behavior comes from the compound itself: Polyurethane (AU/EU) is known for long wear life in dynamic reciprocating service and toughness that outperforms conventional rubber compounds. Applications involving ketones or prolonged humidity at elevated temperature call for a different compound.

Typical settings include mining and heavy equipment, off-highway equipment, and high-pressure fluid power.

Reference part number L31202250375B when ordering; the item is sold individually. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
