APG stocks the L25003250375B, a Polyurethane (AU/EU) Type B Loaded Lip Seal measuring a 3-1/4 in inside diameter, a 3-3/4 in outside diameter, and a height of 3/8 in. A loaded lip seal combines a preloaded lip with pressure activation for consistent dynamic sealing. The catalog record notes: Loaded Lip Seal (type B) Urethane.

Polyurethane (AU/EU) is specified here for outstanding extrusion resistance at elevated pressure and toughness that outperforms conventional rubber compounds. This material stands up to extrusion under high pressure, ozone, and abrasion and wear. Verify compatibility before use with hot water and steam or prolonged humidity at elevated temperature.

You will find this material specified across press and forming equipment, construction machinery, and off-highway equipment.
