-902 BLACK BUNA 50D O-RING

The H50902 is an AS568-902 black Buna-N (Nitrile) 50 Shore A O-Ring supplied with an inside diameter of 0.239 in (6.07 mm), a cross section of 0.064 in (1.63 mm), and an outside diameter of 0.367 in (9.32 mm). This o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

This material stands up to water, greases and lubricants, and many alcohols. That behavior comes from the compound itself: Buna-N (Nitrile) offers an economical choice for high-volume maintenance programs, strong abrasion and tear resistance. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C).

It sees regular use in fluid power, construction equipment, and agricultural equipment.

H50902 ships individually. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
