Part number H50036 is an AS568-036 black Buna-N (Nitrile) 50 Shore A O-Ring supplied with an inside diameter of 2.364 in (60.05 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 2.504 in (63.6 mm). An o-ring delivers dependable bidirectional sealing in a compact groove envelope.
The material holds up against greases and lubricants, petroleum-based oils, and hydraulic fluids. That behavior comes from the compound itself: Buna-N (Nitrile) offers the most widely specified general-purpose sealing elastomer, strong abrasion and tear resistance. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). Exposure to polar solvents or automotive brake fluid will shorten service life.
It sees regular use in construction equipment, general industrial maintenance, and fluid power.
