3-1/4" ID X 4-1/4" OD X 1/2" HT

Ordered as L50003250, this is a Polyurethane (AU/EU) Standard Profile Loaded Lip Seal built to a 3-1/4 in inside diameter, a 4-1/4 in outside diameter, and a height of 1/2 in. The loaded lip seal maintains contact with the sealing surface even as clearances change under load. Supplementary detail from the product record: Loaded Lip Seal (standard) Urethane.

Polyurethane (AU/EU) is specified here for very high tensile strength and load capacity, exceptional abrasion resistance. It resists petroleum oils, ozone, and extrusion under high pressure. Verify compatibility before use with prolonged humidity at elevated temperature or ketones.

You will find this material specified across hydraulic cylinders, press and forming equipment, and mining and heavy equipment.

Stocked as L50003250 and sold individually. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
