-127 BLACK BUNA 70D O-RING

Ordered as H70MD127, this is an AS568-127 black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 1.424 in (36.17 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 1.63 in (41.4 mm). The o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

Expect good resistance to petroleum-based oils, water, and propane and butane. That behavior comes from the compound itself: Buna-N (Nitrile) delivers reliable performance in both static and dynamic service, strong abrasion and tear resistance. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). It should not be specified for service in polar solvents or ozone and direct sunlight.

This item is metal detectable for HACCP and foreign-body control programs. You will find this material specified across automotive, hydraulic and pneumatic systems, and fluid power.

This item is sold individually under part number H70MD127. Nominal inside diameter is listed as 1 7/16 inch. As always, verify media compatibility and operating conditions against the requirements of your specific application.
