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

The L37504375625 is a Polyurethane (AU/EU) Deep Profile Loaded Lip Seal measuring a 4-3/8 inch inside diameter, a 5-1/8 inch outside diameter, and a height of 5/8 inch. This loaded lip seal delivers low-friction dynamic sealing with strong resistance to pressure spikes. Additional detail on this item: Loaded Lip Seal (deep) Urethane.

The material holds up against extrusion under high pressure, petroleum oils, and ozone. Polyurethane (AU/EU) is valued for long wear life in dynamic reciprocating service and exceptional abrasion resistance. Exposure to hot water and steam or ketones will shorten service life.

Maintenance and OEM teams specify it across high-pressure fluid power, mining and heavy equipment, and hydraulic cylinders.
