The L31201437500B is a Polyurethane (AU/EU) Type B Loaded Lip Seal supplied with a 1-7/16 inch inside diameter, a 2-1/16 inch outside diameter, and a height of 1/2 inch. This loaded lip seal combines a preloaded lip with pressure activation for consistent dynamic sealing. Additional detail on this item: Loaded Lip Seal (type B) Urethane.

Polyurethane (AU/EU) is widely chosen for outstanding extrusion resistance at elevated pressure, very high tensile strength and load capacity. Expect good resistance to impact and shock loading, abrasion and wear, and ozone. Exposure to prolonged humidity at elevated temperature or ketones will shorten service life.

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