-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 under 21 CFR 177.2600. Typical settings include agricultural equipment, general industrial maintenance, and automotive.

Order part number H70FDA122, sold individually. Unit weight is approximately 0.68 g and nominal inside diameter is listed as 1 1/8 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
