568-267 GREEN HNBR (HSN) 70 ORINGS

Ordered as HS70267, this is an AS568-267 green HNBR (Hydrogenated Nitrile) 70 Shore A O-Ring measuring an inside diameter of 8.234 in (209.14 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 8.512 in (216.2 mm). The o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

HNBR (Hydrogenated Nitrile) is specified here for strong resistance to rapid gas decompression, improved ozone and weathering resistance over standard nitrile. Expect good resistance to modern refrigerants, heat and oxidation, and petroleum oils and fuels. Service temperature is rated from -40°F (-40°C) through 325°F (162.8°C). Exposure to strong oxidizing acids or esters will shorten service life.

It sees regular use in automotive air conditioning, commercial refrigeration, and heavy-duty powertrain.
