Product Specification

-
The H50150 is an AS568-150 black Buna-N (Nitrile) 50 Shore A O-Ring built to an inside diameter of 2.862 in (72.69 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 3.068 in (77.93 mm). This 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 reliable performance in both static and dynamic service, an economical choice for high-volume maintenance programs. Expect good resistance to greases and lubricants, petroleum-based oils, and propane and butane. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). Applications involving ozone and direct sunlight or automotive brake fluid call for a different compound.

Typical settings include hydraulic and pneumatic systems, agricultural equipment, and fluid power.

H50150 ships individually. As always, verify media compatibility and operating conditions against the requirements of your specific application. For a size or compound outside the standard catalog, APG can quote from a print or sample.
