1.78MM CS X 11.11MM ID BLACK BUNA 70D

The H1.78X11.11 is a black Buna-N (Nitrile) 70 Shore A O-Ring with an inside diameter of 11.11 mm (0.437 in), a cross section of 1.78 mm (0.07 in), and an outside diameter of 14.67 mm (0.58 in). This o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

As a material, Buna-N (Nitrile) is widely chosen for an economical choice for high-volume maintenance programs, reliable performance in both static and dynamic service. The compound resists greases and lubricants, petroleum-based oils, and hydraulic fluids. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). Exposure to polar solvents or ozone and direct sunlight will shorten service life.

Typical settings include automotive, construction equipment, and hydraulic and pneumatic systems.
