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

APG stocks the L18703375375B, a Polyurethane (AU/EU) Type B Loaded Lip Seal with a 3-3/8 inch inside diameter, a 3-3/4 inch outside diameter, and a height of 3/8 inch. A loaded lip seal maintains contact with the sealing surface even as clearances change under load. The catalog record notes: Loaded Lip Seal (type B) Urethane.

Polyurethane (AU/EU) is specified here for very high tensile strength and load capacity, outstanding extrusion resistance at elevated pressure. It resists abrasion and wear, impact and shock loading, and petroleum oils.

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

L18703375375B ships 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.
