Ordered as HS70271, this is an AS568-271 green HNBR (Hydrogenated Nitrile) 70 Shore A O-Ring with an inside diameter of 9.234 in (234.54 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 9.512 in (241.6 mm). The o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

HNBR (Hydrogenated Nitrile) is specified here for excellent abrasion and tear strength, oil resistance of nitrile with substantially better heat capability. The material holds up against ozone and weathering, petroleum oils and fuels, and sour gas and amine inhibitors. The material carries a published service range of -40°F (-40°C) to 325°F (162.8°C). It is not the right choice where strong oxidizing acids or chlorinated hydrocarbons are present.

Typical settings include oilfield and downhole equipment, commercial refrigeration, and engine timing systems.
