1-5/16" ID X 1-15/16" OD X 5/16" HT

L31201312 is a Polyurethane (AU/EU) Standard Profile Loaded Lip Seal supplied with a 1-5/16 inch inside diameter, a 1-15/16 inch outside diameter, and a height of 5/16 inch. In service, this loaded lip seal combines a preloaded lip with pressure activation for consistent dynamic sealing. The catalog record notes: Loaded Lip Seal (standard) Urethane.

The compound resists abrasion and wear, impact and shock loading, and ozone. That behavior comes from the compound itself: Polyurethane (AU/EU) is widely chosen for toughness that outperforms conventional rubber compounds and outstanding extrusion resistance at elevated pressure. Exposure to hot water and steam or ketones will shorten service life.

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