The L18703375375 is a Polyurethane (AU/EU) Deep Profile Loaded Lip Seal supplied with a 3-3/8 inch inside diameter, a 3-3/4 inch outside diameter, and a height of 3/8 inch. This loaded lip seal maintains contact with the sealing surface even as clearances change under load. Supplementary detail from the product record: Loaded Lip Seal (deep) Urethane.

Polyurethane (AU/EU) is specified here for long wear life in dynamic reciprocating service, very high tensile strength and load capacity. This material stands up to ozone, extrusion under high pressure, and petroleum oils. It should not be specified for service in ketones or acids and bases.

You will find this material specified across hydraulic cylinders, off-highway equipment, and high-pressure fluid power.

L18703375375 ships individually. Check the compound against your process media, pressure and temperature before committing to a design. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
