-122 WHITE BUNA 70D FDA O-RING

H70FDA122 is an AS568-122 white Buna-N (Nitrile) 70 Shore A O-Ring 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). In service, 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 petroleum-based oils, propane and butane, and water. That behavior comes from the compound itself: Buna-N (Nitrile) is widely chosen for reliable performance in both static and dynamic service, strong abrasion and tear resistance. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. It is not the right choice where strong acids or ketones are present.

This item meets FDA requirements for food contact, is metal detectable for HACCP and foreign-body control programs. Typical settings include agricultural equipment, general industrial maintenance, and automotive.
