Part number H70MD031 is an AS568-031 black Buna-N (Nitrile) 70 Shore A O-Ring supplied with an inside diameter of 1.739 in (44.17 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 1.879 in (47.73 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

As a material, Buna-N (Nitrile) is widely chosen for the most widely specified general-purpose sealing elastomer and an economical choice for high-volume maintenance programs. Expect good resistance to greases and lubricants, many alcohols, and water. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Verify compatibility before use with polar solvents or ozone and direct sunlight.

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