5/16" ID X 11/16" OD X 5/16" HT

Part number L18700312312B is a Polyurethane (AU/EU) Type B Loaded Lip Seal supplied with a 5/16 in inside diameter, an 11/16 in outside diameter, and a height of 5/16 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 (type B) Urethane.

The compound resists ozone, petroleum oils, and impact and shock loading. That behavior comes from the compound itself: Polyurethane (AU/EU) offers very high tensile strength and load capacity, exceptional abrasion resistance. It should not be specified for service in hot water and steam or prolonged humidity at elevated temperature.

You will find this material specified across press and forming equipment, construction machinery, and high-pressure fluid power.
