3-3/4" ID X 4-1/2" X 1/2" HT

L37503750500 is a Polyurethane (AU/EU) Deep Profile Loaded Lip Seal built to a 3-3/4 inch inside diameter, a 4-1/2 inch outside diameter, and a height of 1/2 inch. In service, this loaded lip seal combines a preloaded lip with pressure activation for consistent dynamic sealing. Additional detail on this item: Loaded Lip Seal (deep) Urethane.

It resists impact and shock loading, petroleum oils, and extrusion under high pressure. That behavior comes from the compound itself: Polyurethane (AU/EU) is widely chosen for very high tensile strength and load capacity, long wear life in dynamic reciprocating service. It should not be specified for service in ketones or acids and bases.

Maintenance and OEM teams specify it across off-highway equipment, construction machinery, and hydraulic cylinders.
