4-1/2" ID X 4-3/4" OD X 1/8" HT

Part number L12504500 is a Polyurethane (AU/EU) Standard Profile Loaded Lip Seal measuring a 4-1/2 in inside diameter, a 4-3/4 in outside diameter, and a height of 1/8 in. A loaded lip seal uses a flexible sealing lip energized by system pressure to hold a tight seal on a moving rod or piston. Source specification: Loaded Lip Seal (standard) Urethane.

Expect good resistance to petroleum oils, abrasion and wear, and extrusion under high pressure. That behavior comes from the compound itself: Polyurethane (AU/EU) is widely chosen for toughness that outperforms conventional rubber compounds and exceptional abrasion resistance. Verify compatibility before use with acids and bases or ketones.

It sees regular use in hydraulic cylinders, off-highway equipment, and construction machinery.
