Ordered as H50314, this is an AS568-314 black Buna-N (Nitrile) 50 Shore A O-Ring measuring an inside diameter of 0.725 in (18.42 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 1.145 in (29.08 mm). The o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.
Buna-N (Nitrile) is specified here for most widely specified general-purpose sealing elastomer and economical choice for high-volume maintenance programs. The compound resists petroleum-based oils, hydraulic fluids, and water. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). Exposure to strong acids or automotive brake fluid will shorten service life.
Common environments for this compound include construction equipment, general industrial maintenance, and hydraulic and pneumatic systems.
H50314 ships individually. Nominal inside diameter is listed as 3/4 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
