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

Ordered as L18704625375B, this is a Polyurethane (AU/EU) Type B Loaded Lip Seal built to a 4-5/8 inch inside diameter, a 5 inch outside diameter, and a height of 3/8 inch. The loaded lip seal combines a preloaded lip with pressure activation for consistent dynamic sealing. This item is further identified as Loaded Lip Seal (type B) Urethane.

As a material, Polyurethane (AU/EU) is widely chosen for toughness that outperforms conventional rubber compounds and exceptional abrasion resistance. The material holds up against impact and shock loading, extrusion under high pressure, and abrasion and wear. Exposure to prolonged humidity at elevated temperature or ketones will shorten service life.

Common environments for this compound include press and forming equipment, off-highway equipment, and mining and heavy equipment.

This item is sold individually under part number L18704625375B. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. 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.
