APG stocks the HS70048, an AS568-048 green HNBR (Hydrogenated Nitrile) 70 Shore A O-Ring measuring an inside diameter of 4.739 in (120.37 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 4.879 in (123.93 mm). An o-ring delivers dependable bidirectional sealing in a compact groove envelope.

HNBR (Hydrogenated Nitrile) is specified here for long service life in refrigerant and oilfield duty, excellent abrasion and tear strength. The compound resists heat and oxidation, modern refrigerants, and petroleum oils and fuels. Continuous operating temperature is published at -40°F (-40°C) to 325°F (162.8°C). Exposure to strong oxidizing acids or chlorinated hydrocarbons will shorten service life.

It sees regular use in oilfield and downhole equipment, commercial refrigeration, and heavy-duty powertrain.
