568-036 GREEN HNBR (HSN) 70 ORINGS

APG stocks the HS70036, an AS568-036 green HNBR (Hydrogenated Nitrile) 70 Shore A O-Ring supplied with an inside diameter of 2.364 in (60.05 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 2.504 in (63.6 mm). An o-ring delivers dependable bidirectional sealing in a compact groove envelope.

It resists ozone and weathering, modern refrigerants, and sour gas and amine inhibitors. That behavior comes from the compound itself: HNBR (Hydrogenated Nitrile) delivers excellent abrasion and tear strength, long service life in refrigerant and oilfield duty. Continuous operating temperature is published at -40°F (-40°C) to 325°F (162.8°C). It should not be specified for service in esters or strong oxidizing acids.

Maintenance and OEM teams specify it across heavy-duty powertrain, oilfield and downhole equipment, and commercial refrigeration.
