568-024 BLACK HNBR HSN70 O-Ring

Ordered as HSN70024, this is an AS568-024 black HNBR (Hydrogenated Nitrile) 70 Shore A O-Ring measuring an inside diameter of 1.114 in (28.3 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 1.254 in (31.85 mm). The o-ring compresses into its gland to block fluid or gas migration across a joint.

The compound resists heat and oxidation, sour gas and amine inhibitors, and petroleum oils and fuels. That behavior comes from the compound itself: HNBR (Hydrogenated Nitrile) is widely chosen for long service life in refrigerant and oilfield duty, the oil resistance of nitrile with substantially better heat capability. Rated temperature range runs from -40°F (-40°C) to 325°F (162.8°C) in continuous service. Exposure to strong oxidizing acids or esters will shorten service life.

Typical settings include oilfield and downhole equipment, commercial refrigeration, and heavy-duty powertrain.
