7-1/2" ID X 8-1/4" OD X 5/8" HT

This loaded lip seal is supplied in Polyurethane (AU/EU) with a 7-1/2 in inside diameter, an 8-1/4 in outside diameter, and a height of 5/8 in, catalogued under part number L37507500625B. It uses a flexible sealing lip energized by system pressure to hold a tight seal on a moving rod or piston. Supplementary detail from the product record: Loaded Lip Seal (type B) Urethane.

It resists petroleum oils, abrasion and wear, and ozone. That behavior comes from the compound itself: Polyurethane (AU/EU) is widely chosen for very high tensile strength and load capacity, exceptional abrasion resistance. Verify compatibility before use with ketones or hot water and steam.

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

Reference part number L37507500625B when ordering; the item is sold individually. Check the compound against your process media, pressure and temperature before committing to a design. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
