The L31204125 is a Polyurethane (AU/EU) Standard Profile Loaded Lip Seal supplied with a 4-1/8 in inside diameter, a 4-3/4 in outside diameter, and a height of 5/16 in. This loaded lip seal combines a preloaded lip with pressure activation for consistent dynamic sealing. Source specification: Loaded Lip Seal (standard) Urethane.

Polyurethane (AU/EU) is specified here for outstanding extrusion resistance at elevated pressure and exceptional abrasion resistance. The material holds up against abrasion and wear, impact and shock loading, and petroleum oils. It is not the right choice where hot water and steam or prolonged humidity at elevated temperature are present.

Maintenance and OEM teams specify it across press and forming equipment, hydraulic cylinders, and mining and heavy equipment.
