1-11/16" ID X 2-5/16" OD X 1/2" HT

This loaded lip seal is supplied in Polyurethane (AU/EU) with a 1-11/16 inch inside diameter, a 2-5/16 inch outside diameter, and a height of 1/2 inch, catalogued under part number L31201687500B. It delivers low-friction dynamic sealing with strong resistance to pressure spikes. This item is further identified as Loaded Lip Seal (type B) Urethane.

It resists impact and shock loading, extrusion under high pressure, and abrasion and wear. That behavior comes from the compound itself: Polyurethane (AU/EU) is widely chosen for exceptional abrasion resistance and toughness that outperforms conventional rubber compounds. Verify compatibility before use with acids and bases or hot water and steam.

You will find this material specified across off-highway equipment, mining and heavy equipment, and hydraulic cylinders.

Stocked as L31201687500B and sold individually. As always, verify media compatibility and operating conditions against the requirements of your specific application. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
