1MM CS X 6.5MM ID BLACK BUNA 70D

H1X6.5 is a black Buna-N (Nitrile) 70 Shore A O-Ring with an inside diameter of 6.5 mm (0.256 in), a cross section of 1 mm (0.039 in), and an outside diameter of 8.5 mm (0.33 in). In service, this o-ring compresses into its gland to block fluid or gas migration across a joint.

It resists hydraulic fluids, water, and propane and butane. That behavior comes from the compound itself: Buna-N (Nitrile) is widely chosen for reliable performance in both static and dynamic service, the most widely specified general-purpose sealing elastomer. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). It should not be specified for service in polar solvents or strong acids.

Common environments for this compound include general industrial maintenance, fluid power, and construction equipment.

H1X6.5 ships individually. Unit weight is approximately 0.0228 g. Check the compound against your process media, pressure and temperature before committing to a design.
