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

This loaded lip seal is supplied in Polyurethane (AU/EU) built to a 3-3/8 inch inside diameter, a 4 inch outside diameter, and a height of 1/2 inch, catalogued under part number L31203375500B. It uses a flexible sealing lip energized by system pressure to hold a tight seal on a moving rod or piston. Source specification: Loaded Lip Seal (type B) Urethane.

This material stands up to extrusion under high pressure, impact and shock loading, and ozone. That behavior comes from the compound itself: Polyurethane (AU/EU) is specified for outstanding extrusion resistance at elevated pressure, very high tensile strength and load capacity. Verify compatibility before use with ketones or prolonged humidity at elevated temperature.

It sees regular use in press and forming equipment, construction machinery, and high-pressure fluid power.

L31203375500B ships individually. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
