4-5/8" ID X 5-1/8" OD X 1/4" HT

Part number L25004625250B is a Polyurethane (AU/EU) Type B Loaded Lip Seal supplied with a 4-5/8 in inside diameter, a 5-1/8 in outside diameter, and a height of 1/4 in. A loaded lip seal maintains contact with the sealing surface even as clearances change under load. Source specification: Loaded Lip Seal (type B) Urethane.

It resists petroleum oils, impact and shock loading, and ozone. That behavior comes from the compound itself: Polyurethane (AU/EU) delivers very high tensile strength and load capacity, toughness that outperforms conventional rubber compounds. Exposure to prolonged humidity at elevated temperature or ketones will shorten service life.

It sees regular use in hydraulic cylinders, mining and heavy equipment, and high-pressure fluid power.
