4-3/4" ID X 5-3/4" OD X 1/2" HT

Part number L50004750 is a Polyurethane (AU/EU) Standard Profile Loaded Lip Seal built to a 4-3/4 inch inside diameter, a 5-3/4 inch outside diameter, and a height of 1/2 inch. A loaded lip seal combines a preloaded lip with pressure activation for consistent dynamic sealing. This item is further identified as Loaded Lip Seal (standard) Urethane.

The compound resists impact and shock loading, petroleum oils, and extrusion under high pressure. That behavior comes from the compound itself: Polyurethane (AU/EU) is valued for very high tensile strength and load capacity, outstanding extrusion resistance at elevated pressure. Applications involving acids and bases or hot water and steam call for a different compound.

Common environments for this compound include high-pressure fluid power, hydraulic cylinders, and construction machinery.
