*3-3/8" ID X 3-7/8" OD X 3/8" HT

The L25003375375B is a Polyurethane (AU/EU) Type B Loaded Lip Seal with a 3-3/8 inch inside diameter, a 3-7/8 inch outside diameter, and a height of 3/8 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. Source specification: Loaded Lip Seal (type B) Urethane.

Polyurethane (AU/EU) is specified here for toughness that outperforms conventional rubber compounds and long wear life in dynamic reciprocating service. It resists extrusion under high pressure, impact and shock loading, and petroleum oils. Verify compatibility before use with prolonged humidity at elevated temperature or ketones.

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

L25003375375B ships individually. Application requirements vary, so validate compatibility with your process conditions prior to installation.
