4-1/4" ID X 5" OD X 3/8" HT

Part number L37504250 is a Polyurethane (AU/EU) Standard Profile Loaded Lip Seal measuring a 4-1/4 inch inside diameter, a 5 inch outside diameter, and a height of 3/8 inch. A loaded lip seal combines a preloaded lip with pressure activation for consistent dynamic sealing. The catalog record notes: Loaded Lip Seal (standard) Urethane.

Polyurethane (AU/EU) is specified for very high tensile strength and load capacity, toughness that outperforms conventional rubber compounds. It resists impact and shock loading, extrusion under high pressure, and petroleum oils. Exposure to acids and bases or prolonged humidity at elevated temperature will shorten service life.

Common environments for this compound include press and forming equipment, hydraulic cylinders, and construction machinery.

L37504250 ships individually. As always, verify media compatibility and operating conditions against the requirements of your specific application.
