Product Specification

-
The H50122 is an AS568-122 black Buna-N (Nitrile) 50 Shore A O-Ring supplied with an inside diameter of 1.112 in (28.24 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 1.318 in (33.48 mm). This o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

Buna-N (Nitrile) offers the most widely specified general-purpose sealing elastomer and low compression set under sustained load. Expect good resistance to propane and butane, greases and lubricants, and many alcohols. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). Verify compatibility before use with polar solvents or automotive brake fluid.

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

H50122 ships individually. Nominal inside diameter is listed as 1 1/8 inch. Check the compound against your process media, pressure and temperature before committing to a design. For a size or compound outside the standard catalog, APG can quote from a print or sample.
