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

Urethane deep loaded lip seal, item L18701000312, for hydraulic and pneumatic sealing applications where a resilient lip design is needed around a rod or piston. This deep loaded lip seal is built for cylinders, presses, lift equipment, production machinery, and MRO repair work where oil retention, pressure control, and repeatable motion sealing are important. The product is listed with nominal dimensions of 1 inch ID x 1 3/8 inch OD x 5/16 inch height and actual dimensions of 1 inch (25.4 mm) ID x 1.375 inch (34.93 mm) OD x 0.3125 inch (8 mm) cross-section/height, giving buyers a practical way to compare the seal against gland drawings, worn samples, and maintenance documentation. The deep profile supports applications that require a taller sealing element and a more substantial cross section within the gland. Urethane is commonly selected for abrasion resistance, extrusion resistance, and durability in dynamic sealing environments. This product supports common buying terms such as hydraulic lip seal, urethane rod seal, piston seal, loaded lip seal, and replacement cylinder seal while remaining specific to the supplied material, style, and dimensions. Item L18701000312 is included for SKU-level identification in equipment records, drawings, maintenance lists, and reseller product catalogs.
