1 7/8" ID X 2 1/8" OD X 1/8" HT

Part number L12501875125B is a Polyurethane (AU/EU) Type B Loaded Lip Seal supplied with a 1-7/8 in inside diameter, a 2-1/8 in outside diameter, and a height of 1/8 in. A loaded lip seal combines a preloaded lip with pressure activation for consistent dynamic sealing. This item is further identified as Loaded Lip Seal (type B) Urethane.

It resists extrusion under high pressure, petroleum oils, and ozone. That behavior comes from the compound itself: Polyurethane (AU/EU) is widely chosen for outstanding extrusion resistance at elevated pressure and long wear life in dynamic reciprocating service. Exposure to prolonged humidity at elevated temperature or ketones will shorten service life.

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