Ordered as L25004000, this is a Polyurethane (AU/EU) Standard Profile Loaded Lip Seal built to a 4 inch inside diameter, a 4-1/2 inch outside diameter, and a height of 1/4 inch. The loaded lip seal combines a preloaded lip with pressure activation for consistent dynamic sealing. The catalog record notes: Loaded Lip Seal (standard) Urethane.

Polyurethane (AU/EU) is specified here for long wear life in dynamic reciprocating service and toughness that outperforms conventional rubber compounds. The compound resists abrasion and wear, impact and shock loading, and petroleum oils. Exposure to prolonged humidity at elevated temperature or ketones will shorten service life.

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