4" ID X 4-1/2" OD X 9/16" HT

Ordered as L25004000562B, this is a Polyurethane (AU/EU) Type B Loaded Lip Seal built to a 4 inch inside diameter, a 4-1/2 inch outside diameter, and a height of 9/16 inch. The loaded lip seal delivers low-friction dynamic sealing with strong resistance to pressure spikes. Source specification: Loaded Lip Seal (type B) Urethane.

The compound resists petroleum oils, impact and shock loading, and ozone. Polyurethane (AU/EU) is valued for toughness that outperforms conventional rubber compounds and outstanding extrusion resistance at elevated pressure. Verify compatibility before use with ketones or hot water and steam.

Common environments for this compound include hydraulic cylinders, high-pressure fluid power, and construction machinery.

L25004000562B ships 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.
