Ordered as H70126, this is an AS568-126 black Buna-N (Nitrile) 70 Shore A O-Ring supplied with an inside diameter of 1.362 in (34.59 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 1.568 in (39.83 mm). The o-ring remains the most cost-effective sealing element available for pressurized assemblies.
Expect good resistance to hydraulic fluids, petroleum-based oils, and greases and lubricants. That behavior comes from the compound itself: Buna-N (Nitrile) is valued for an economical choice for high-volume maintenance programs and the most widely specified general-purpose sealing elastomer. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). Exposure to strong acids or ozone and direct sunlight will shorten service life.
Common environments for this compound include fluid power, hydraulic and pneumatic systems, and agricultural equipment.
Stocked as H70126 and sold individually. Unit weight is approximately 0.772 g. Application requirements vary, so validate compatibility with your process conditions prior to installation. For a size or compound outside the standard catalog, APG can quote from a print or sample.
