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

Ordered as L31201750500B, this is a Polyurethane (AU/EU) Type B Loaded Lip Seal measuring a 1-3/4 inch inside diameter, a 2-3/8 inch outside diameter, and a height of 1/2 inch. The loaded lip seal uses a flexible sealing lip energized by system pressure to hold a tight seal on a moving rod or piston. This item is further identified as Loaded Lip Seal (type B) Urethane.

As a material, Polyurethane (AU/EU) is widely chosen for outstanding extrusion resistance at elevated pressure and long wear life in dynamic reciprocating service. This material stands up to extrusion under high pressure, impact and shock loading, and abrasion and wear. It is not the right choice where ketones or hot water and steam are present.

Maintenance and OEM teams specify it across press and forming equipment, mining and heavy equipment, and construction machinery.
