APG stocks the L18703000250B, a Polyurethane (AU/EU) Type B Loaded Lip Seal with a 3 inch inside diameter, a 3-3/8 inch outside diameter, and a height of 1/4 inch. A loaded lip seal combines a preloaded lip with pressure activation for consistent dynamic sealing. The catalog record notes: Loaded Lip Seal (type B) Urethane.

Polyurethane (AU/EU) is specified here for very high tensile strength and load capacity, long wear life in dynamic reciprocating service. The material holds up against impact and shock loading, abrasion and wear, and petroleum oils. Exposure to acids and bases or prolonged humidity at elevated temperature will shorten service life.

It sees regular use in construction machinery, mining and heavy equipment, and high-pressure fluid power.

L18703000250B ships individually. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
