3-3/4" ID X 5" OD X 5/8" HT

Ordered as L62503750, this is a Polyurethane (AU/EU) Standard Profile Loaded Lip Seal supplied with a 3-3/4 in inside diameter, a 5 in outside diameter, and a height of 5/8 in. The loaded lip seal delivers low-friction dynamic sealing with strong resistance to pressure spikes. The catalog record notes: Loaded Lip Seal (standard) Urethane.

This material stands up to extrusion under high pressure, petroleum oils, and impact and shock loading. That behavior comes from the compound itself: Polyurethane (AU/EU) is widely chosen for toughness that outperforms conventional rubber compounds, very high tensile strength and load capacity. It should not be specified for service in acids and bases or hot water and steam.

You will find this material specified across construction machinery, hydraulic cylinders, and high-pressure fluid power.

Reference part number L62503750 when ordering; the item is sold individually. Check the compound against your process media, pressure and temperature before committing to a design.
