4-7/16" ID X 5" OD X 9/32" HT

The L28104437 is a Polyurethane (AU/EU) Standard Profile Loaded Lip Seal with a 4-7/16 in inside diameter, a 5 in outside diameter, and a height of 9/32 in. This 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.

Polyurethane (AU/EU) is specified here for outstanding extrusion resistance at elevated pressure and toughness that outperforms conventional rubber compounds. The material holds up against petroleum oils, impact and shock loading, and abrasion and wear. Exposure to prolonged humidity at elevated temperature or acids and bases will shorten service life.

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