1MM CS X 50MM ID BLACK BUNA 70D

APG stocks the H1X50, a black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 50 mm (1.969 in), a cross section of 1 mm (0.039 in), and an outside diameter of 52 mm (2.05 in). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

As a material, Buna-N (Nitrile) is specified for low compression set under sustained load, reliable performance in both static and dynamic service. The compound resists hydraulic fluids, petroleum-based oils, and many alcohols. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). Applications involving automotive brake fluid or ozone and direct sunlight call for a different compound.

Common environments for this compound include general industrial maintenance, construction equipment, and fluid power.
