Ordered as SB-H70207-100, this is an AS568-207 black Buna-N (Nitrile) 70 Shore A O-Ring measuring an inside diameter of 0.546 in (13.87 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 0.824 in (20.93 mm). The o-ring remains the most cost-effective sealing element available for pressurized assemblies. This item is further identified as.8125IDX.5625"ODX.125"CS.
As a material, Buna-N (Nitrile) offers an economical choice for high-volume maintenance programs, strong abrasion and tear resistance. It resists petroleum-based oils, many alcohols, and greases and lubricants. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Exposure to strong acids or polar solvents will shorten service life.
Common environments for this compound include fluid power, construction equipment, and hydraulic and pneumatic systems.
SB-H70207-100 ships by the bag. Nominal inside diameter is listed as 9/16 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation. 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.
