4-3/8" ID X 4-7/8" OD X 1/4" HT

L25004375 is a Polyurethane (AU/EU) Standard Profile Loaded Lip Seal built to a 4-3/8 in inside diameter, a 4-7/8 in outside diameter, and a height of 1/4 in. In service, this loaded lip seal maintains contact with the sealing surface even as clearances change under load. This item is further identified as Loaded Lip Seal (standard) Urethane.

Polyurethane (AU/EU) is specified for toughness that outperforms conventional rubber compounds and exceptional abrasion resistance. Expect good resistance to abrasion and wear, extrusion under high pressure, and impact and shock loading. Applications involving acids and bases or ketones call for a different compound.

It sees regular use in high-pressure fluid power, construction machinery, and hydraulic cylinders.

L25004375 ships individually. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. For a size or compound outside the standard catalog, APG can quote from a print or sample.
