-141 BLACK BUNA 50D O-RING

H50141 is an AS568-141 black Buna-N (Nitrile) 50 Shore A O-Ring supplied with an inside diameter of 2.3 in (58.42 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 2.506 in (63.65 mm). In service, this o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

Buna-N (Nitrile) is widely chosen for low compression set under sustained load, strong abrasion and tear resistance. It resists hydraulic fluids, water, and propane and butane. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). Exposure to strong acids or automotive brake fluid will shorten service life.

Typical settings include agricultural equipment, general industrial maintenance, and automotive.

Stocked as H50141 and sold individually. Unit weight is approximately 0.0014 g and nominal inside diameter is listed as 2 5/16 inch.
