L18701750312 is a Polyurethane (AU/EU) Deep Profile Loaded Lip Seal with a 1-3/4 inch inside diameter, a 2-1/8 inch outside diameter, and a height of 5/16 inch. In service, this 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 (deep) Urethane.

The material holds up against impact and shock loading, abrasion and wear, and ozone. Polyurethane (AU/EU) is valued for toughness that outperforms conventional rubber compounds and long wear life in dynamic reciprocating service. Verify compatibility before use with acids and bases or prolonged humidity at elevated temperature.

Maintenance and OEM teams specify it across hydraulic cylinders, off-highway equipment, and press and forming equipment.
