2.4MM CS X 54.6MM ID BLACK BUNA 70D

This o-ring is supplied in black Buna-N (Nitrile) 70 Shore A built to an inside diameter of 54.6 mm (2.15 in), a cross section of 2.4 mm (0.094 in), and an outside diameter of 59.4 mm (2.34 in), catalogued under part number H2.4X54.6. It creates a positive seal at flange, piston and rod interfaces without added hardware.

This material stands up to many alcohols, petroleum-based oils, and hydraulic fluids. That behavior comes from the compound itself: Buna-N (Nitrile) delivers an economical choice for high-volume maintenance programs and low compression set under sustained load. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). Applications involving ketones or polar solvents call for a different compound.

It sees regular use in hydraulic and pneumatic systems, automotive, and general industrial maintenance.
