2MM CS X 59MM ID BLACK BUNA 70D

APG stocks the H2X59, a black Buna-N (Nitrile) 70 Shore A O-Ring with an inside diameter of 59 mm (2.323 in), a cross section of 2 mm (0.079 in), and an outside diameter of 63 mm (2.48 in). An o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

Buna-N (Nitrile) is specified for reliable performance in both static and dynamic service, low compression set under sustained load. Expect good resistance to water, hydraulic fluids, and many alcohols. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). Applications involving automotive brake fluid or polar solvents call for a different compound.

Typical settings include hydraulic and pneumatic systems, construction equipment, and general industrial maintenance.

H2X59 ships individually. Unit weight is approximately 0.0008 g. Check the compound against your process media, pressure and temperature before committing to a design. If you need a size, durometer or compound that is not listed, APG can cross-reference from a print, a sample or a competitor part number.
