1.9MM CS X 5.7MM ID BLACK BUNA 70D

APG stocks the H1.9X5.7, a black Buna-N (Nitrile) 70 Shore A O-Ring supplied with an inside diameter of 5.7 mm (0.224 in), a cross section of 1.9 mm (0.075 in), and an outside diameter of 9.5 mm (0.37 in). An o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

Expect good resistance to petroleum-based oils, water, and hydraulic fluids. That behavior comes from the compound itself: Buna-N (Nitrile) is widely chosen for an economical choice for high-volume maintenance programs, reliable performance in both static and dynamic service. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). It should not be specified for service in strong acids or polar solvents.

You will find this material specified across agricultural equipment, hydraulic and pneumatic systems, and fluid power.
