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.
This item is sold individually under part number H70MD114. Nominal inside diameter is listed as 5/8 inch.
