The L31204000562B is a Polyurethane (AU/EU) Type B Loaded Lip Seal with a 4 inch inside diameter, a 4-5/8 inch outside diameter, and a height of 9/16 inch. This loaded lip seal combines a preloaded lip with pressure activation for consistent dynamic sealing. Supplementary detail from the product record: Loaded Lip Seal (type B) Urethane.

As a material, Polyurethane (AU/EU) is valued for long wear life in dynamic reciprocating service and toughness that outperforms conventional rubber compounds. The material holds up against extrusion under high pressure, ozone, and abrasion and wear. Exposure to prolonged humidity at elevated temperature or ketones will shorten service life.

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