3MM CS X 150MM ID BLACK BUNA 70D

H3X150 is a black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 150 mm (5.906 in), a cross section of 3 mm (0.118 in), and an outside diameter of 156 mm (6.14 in). In service, this o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

Expect good resistance to propane and butane, water, and greases and lubricants. That behavior comes from the compound itself: Buna-N (Nitrile) is known for low compression set under sustained load and the most widely specified general-purpose sealing elastomer. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service.

Typical settings include hydraulic and pneumatic systems, fluid power, and automotive.
