2MM CS X 16.5MM ID BLACK BUNA 70D

APG stocks the H2X16.5, a black Buna-N (Nitrile) 70 Shore A O-Ring supplied with an inside diameter of 16.5 mm (0.65 in), a cross section of 2 mm (0.079 in), and an outside diameter of 20.5 mm (0.81 in). An o-ring delivers dependable bidirectional sealing in a compact groove envelope.

The material holds up against propane and butane, water, and greases and lubricants. That behavior comes from the compound itself: Buna-N (Nitrile) is widely chosen for an economical choice for high-volume maintenance programs and low compression set under sustained load. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Applications involving strong acids or automotive brake fluid call for a different compound.

You will find this material specified across general industrial maintenance, automotive, and fluid power.
