4-1/4" ID X 4-5/8" OD X 3/16" HT

APG stocks the L18704250, a Polyurethane (AU/EU) Standard Profile Loaded Lip Seal built to a 4-1/4 in inside diameter, a 4-5/8 in outside diameter, and a height of 3/16 in. A loaded lip seal maintains contact with the sealing surface even as clearances change under load. Additional detail on this item: Loaded Lip Seal (standard) Urethane.

This material stands up to abrasion and wear, impact and shock loading, and extrusion under high pressure. That behavior comes from the compound itself: Polyurethane (AU/EU) delivers toughness that outperforms conventional rubber compounds and outstanding extrusion resistance at elevated pressure. Exposure to ketones or hot water and steam will shorten service life.

Common environments for this compound include high-pressure fluid power, mining and heavy equipment, and press and forming equipment.

This item is sold individually under part number L18704250. Application requirements vary, so validate compatibility with your process conditions prior to installation. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
