Ordered as H1X22.5, this is a black Buna-N (Nitrile) 70 Shore A O-Ring supplied with an inside diameter of 22.5 mm (0.886 in), a cross section of 1 mm (0.039 in), and an outside diameter of 24.5 mm (0.96 in). The o-ring remains the most cost-effective sealing element available for pressurized assemblies.
This material stands up to propane and butane, many alcohols, and greases and lubricants. That behavior comes from the compound itself: Buna-N (Nitrile) is known for strong abrasion and tear resistance, an economical choice for high-volume maintenance programs. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). Applications involving automotive brake fluid or ozone and direct sunlight call for a different compound.
Common environments for this compound include general industrial maintenance, hydraulic and pneumatic systems, and automotive.
This item is sold individually under part number H1X22.5. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
