The H10X840 is a black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 840 mm (33.071 in), a cross section of 10 mm (0.394 in), and an outside diameter of 860 mm (33.86 in). This o-ring compresses into its gland to block fluid or gas migration across a joint.
The compound resists water, greases and lubricants, and propane and butane. That behavior comes from the compound itself: Buna-N (Nitrile) is widely chosen for the most widely specified general-purpose sealing elastomer and an economical choice for high-volume maintenance programs. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). Exposure to automotive brake fluid or polar solvents will shorten service life.
Common environments for this compound include hydraulic and pneumatic systems, general industrial maintenance, and construction equipment.
This item is sold individually under part number H10X840. As always, verify media compatibility and operating conditions against the requirements of your specific application. Not finding the exact configuration you need? APG cross-references from prints, samples and competitor part numbers.
