Part number L50003750750B is a Polyurethane (AU/EU) Type B Loaded Lip Seal measuring a 3-3/4 inch inside diameter, a 4-3/4 inch outside diameter, and a height of 3/4 inch. A loaded lip seal combines a preloaded lip with pressure activation for consistent dynamic sealing. Supplementary detail from the product record: Loaded Lip Seal (type B) Urethane.

The compound resists abrasion and wear, petroleum oils, and ozone. That behavior comes from the compound itself: Polyurethane (AU/EU) is widely chosen for toughness that outperforms conventional rubber compounds and exceptional abrasion resistance.

It sees regular use in press and forming equipment, mining and heavy equipment, and off-highway equipment.
