5-1/2" ID X 6" OD X 9/16" HT

L25005500562B is a Polyurethane (AU/EU) Type B Loaded Lip Seal measuring a 5-1/2 inch inside diameter, a 6 inch outside diameter, and a height of 9/16 inch. In service, this loaded lip seal uses a flexible sealing lip energized by system pressure to hold a tight seal on a moving rod or piston. Source specification: Loaded Lip Seal (type B) Urethane.

Expect good resistance to petroleum oils, extrusion under high pressure, and ozone. That behavior comes from the compound itself: Polyurethane (AU/EU) is valued for very high tensile strength and load capacity, toughness that outperforms conventional rubber compounds. It should not be specified for service in hot water and steam or prolonged humidity at elevated temperature.

Maintenance and OEM teams specify it across hydraulic cylinders, off-highway equipment, and press and forming equipment.
