L50003500750B is a Polyurethane (AU/EU) Type B Loaded Lip Seal supplied with a 3-1/2 inch inside diameter, a 4-1/2 inch outside diameter, and a height of 3/4 inch.

This material stands up to extrusion under high pressure, petroleum oils, and impact and shock loading. That behavior comes from the compound itself: Polyurethane (AU/EU) offers toughness that outperforms conventional rubber compounds and exceptional abrasion resistance. It should not be specified for service in hot water and steam or acids and bases.

Typical settings include press and forming equipment, high-pressure fluid power, and mining and heavy equipment.
