1-1/2" ID X 1-7/8" OD X 3/8" HT

APG stocks the L18701500375, a Polyurethane (AU/EU) Deep Profile Loaded Lip Seal measuring a 1-1/2 in inside diameter, a 1-7/8 in outside diameter, and a height of 3/8 in. A loaded lip seal maintains contact with the sealing surface even as clearances change under load. The catalog record notes: Loaded Lip Seal (deep) Urethane.

The compound resists extrusion under high pressure, petroleum oils, and abrasion and wear. That behavior comes from the compound itself: Polyurethane (AU/EU) is known for outstanding extrusion resistance at elevated pressure and long wear life in dynamic reciprocating service. Exposure to ketones or hot water and steam will shorten service life.

Maintenance and OEM teams specify it across mining and heavy equipment, construction machinery, and hydraulic cylinders.
