Part number L37504125 is a Polyurethane (AU/EU) Standard Profile Loaded Lip Seal measuring a 4-1/8 inch inside diameter, a 4-7/8 inch outside diameter, and a height of 3/8 inch.

As a material, Polyurethane (AU/EU) is specified for toughness that outperforms conventional rubber compounds and exceptional abrasion resistance. This material stands up to impact and shock loading, extrusion under high pressure, and petroleum oils. Exposure to acids and bases or hot water and steam will shorten service life.

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