1.9MM CS X 8MM ID BLACK BUNA 70D

APG stocks the H1.9X8, a black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 8 mm (0.315 in), a cross section of 1.9 mm (0.075 in), and an outside diameter of 11.8 mm (0.46 in). An o-ring delivers dependable bidirectional sealing in a compact groove envelope.

The material holds up against hydraulic fluids, water, and greases and lubricants. That behavior comes from the compound itself: Buna-N (Nitrile) is known for the most widely specified general-purpose sealing elastomer and an economical choice for high-volume maintenance programs. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C). It is not the right choice where ozone and direct sunlight or strong acids are present.

You will find this material specified across general industrial maintenance, hydraulic and pneumatic systems, and fluid power.

Reference part number H1.9X8 when ordering; the item is sold individually. As always, verify media compatibility and operating conditions against the requirements of your specific application.
