4-1/4" ID X 4-5/8" OD X 3/8" HT

Part number L18704250375B is a Polyurethane (AU/EU) Type B Loaded Lip Seal with a 4-1/4 inch inside diameter, a 4-5/8 inch outside diameter, and a height of 3/8 inch. A loaded lip seal maintains contact with the sealing surface even as clearances change under load. This item is further identified as Loaded Lip Seal (type B) Urethane.

Polyurethane (AU/EU) is specified here for very high tensile strength and load capacity, exceptional abrasion resistance. Expect good resistance to extrusion under high pressure, petroleum oils, and impact and shock loading. It is not the right choice where prolonged humidity at elevated temperature or ketones are present.

Typical settings include press and forming equipment, mining and heavy equipment, and off-highway equipment.

L18704250375B ships individually. Review your operating media and conditions against this specification before installation. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
