*568-275 BLACK HNBR HSN70 O-Ring

The HSN70275 is an AS568-275 black HNBR (Hydrogenated Nitrile) 70 Shore A O-Ring built to an inside diameter of 10.484 in (266.29 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 10.762 in (273.35 mm). This o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

The material holds up against ozone and weathering, petroleum oils and fuels, and sour gas and amine inhibitors. HNBR (Hydrogenated Nitrile) is widely chosen for long service life in refrigerant and oilfield duty, improved ozone and weathering resistance over standard nitrile. Published continuous service range is -40°F (-40°C) to 325°F (162.8°C).

Common environments for this compound include heavy-duty powertrain, engine timing systems, and commercial refrigeration.
