Part number L50004125750B is a Polyurethane (AU/EU) Type B Loaded Lip Seal supplied with a 4-1/8 inch inside diameter, a 5-1/8 inch outside diameter, and a height of 3/4 inch. A loaded lip seal maintains contact with the sealing surface even as clearances change under load. The catalog record notes: Loaded Lip Seal (type B) Urethane.

Polyurethane (AU/EU) is specified here for long wear life in dynamic reciprocating service, very high tensile strength and load capacity. Expect good resistance to abrasion and wear, impact and shock loading, and ozone. It is not the right choice where hot water and steam or prolonged humidity at elevated temperature are present.

Typical settings include high-pressure fluid power, off-highway equipment, and press and forming equipment.
