3-1/2" ID X 3-7/8" OD X 9/32" HT

Ordered as L18703500281B, this is a Polyurethane (AU/EU) Type B Loaded Lip Seal measuring a 3-1/2 inch inside diameter, a 3-7/8 inch outside diameter, and a height of 9/32 inch. The loaded lip seal maintains contact with the sealing surface even as clearances change under load. Additional detail on this item: Loaded Lip Seal (type B) Urethane.

Expect good resistance to extrusion under high pressure, ozone, and abrasion and wear. That behavior comes from the compound itself: Polyurethane (AU/EU) delivers very high tensile strength and load capacity, long wear life in dynamic reciprocating service. It is not the right choice where acids and bases or ketones are present.

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