1-3/4" ID X 2-1/2" OD X 5/8" HT

The L37501750625B is a Polyurethane (AU/EU) Type B Loaded Lip Seal built to a 1-3/4 inch inside diameter, a 2-1/2 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. Source specification: Loaded Lip Seal (type B) Urethane.

The material holds up against impact and shock loading, ozone, and extrusion under high pressure. That behavior comes from the compound itself: Polyurethane (AU/EU) delivers very high tensile strength and load capacity, long wear life in dynamic reciprocating service. It is not the right choice where acids and bases or hot water and steam are present.

Maintenance and OEM teams specify it across off-highway equipment, high-pressure fluid power, and construction machinery.

Order part number L37501750625B, sold individually. As always, verify media compatibility and operating conditions against the requirements of your specific application. For a size or compound outside the standard catalog, APG can quote from a print or sample.
