-114 BLACK BUNA 70D O-RING

Part number H70MD114 is an AS568-114 black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 0.612 in (15.54 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 0.818 in (20.78 mm). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

The material holds up against propane and butane, many alcohols, and petroleum-based oils. That behavior comes from the compound itself: Buna-N (Nitrile) is known for reliable performance in both static and dynamic service, low compression set under sustained load. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service.

The compound is metal detectable for HACCP and foreign-body control programs. Typical settings include general industrial maintenance, fluid power, and hydraulic and pneumatic systems.
