Product Specification

-
Part number H2X156 is a black Buna-N (Nitrile) 70 Shore A O-Ring supplied with an inside diameter of 156 mm (6.142 in), a cross section of 2 mm (0.079 in), and an outside diameter of 160 mm (6.3 in). An 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 economical choice for high-volume maintenance programs, reliable performance in both static and dynamic service. Expect good resistance to greases and lubricants, petroleum-based oils, and water. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). Exposure to polar solvents or ozone and direct sunlight will shorten service life.

You will find this material specified across general industrial maintenance, hydraulic and pneumatic systems, and fluid power.

H2X156 ships individually. Unit weight is approximately 1.9423 g. Check the compound against your process media, pressure and temperature before committing to a design.
