Ordered as H70226, this is an AS568-226 black Buna-N (Nitrile) 70 Shore A O-Ring measuring an inside diameter of 1.984 in (50.39 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 2.262 in (57.45 mm). The o-ring remains the most cost-effective sealing element available for pressurized assemblies.
Buna-N (Nitrile) is known for strong abrasion and tear resistance, the most widely specified general-purpose sealing elastomer. The compound resists hydraulic fluids, propane and butane, and petroleum-based oils. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Exposure to strong acids or ketones will shorten service life.
Typical settings include automotive, hydraulic and pneumatic systems, and general industrial maintenance.
This item is sold individually under part number H70226. Unit weight is approximately 0.0021 g and nominal inside diameter is listed as 2 inch. Review your operating media and conditions against this specification before installation.
