The L12501750187B is a Polyurethane (AU/EU) Type B Loaded Lip Seal supplied with a 1-3/4 inch inside diameter, a 2 inch outside diameter, and a height of 3/16 inch. This loaded lip seal uses a flexible sealing lip energized by system pressure to hold a tight seal on a moving rod or piston. The catalog record notes: Loaded Lip Seal (type B) Urethane.

Polyurethane (AU/EU) is specified here for toughness that outperforms conventional rubber compounds and exceptional abrasion resistance. The material holds up against ozone, extrusion under high pressure, and petroleum oils. It should not be specified for service in prolonged humidity at elevated temperature or hot water and steam.

Maintenance and OEM teams specify it across construction machinery, high-pressure fluid power, and press and forming equipment.
