Part number HS70441 is an AS568-441 green HNBR (Hydrogenated Nitrile) 70 Shore A O-Ring measuring an inside diameter of 6.975 in (177.17 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 7.525 in (191.14 mm). An o-ring delivers dependable bidirectional sealing in a compact groove envelope.

HNBR (Hydrogenated Nitrile) is known for improved ozone and weathering resistance over standard nitrile, excellent abrasion and tear strength. It resists modern refrigerants, ozone and weathering, and heat and oxidation. Rated temperature range runs from -40°F (-40°C) to 325°F (162.8°C) in continuous service. Exposure to esters or chlorinated hydrocarbons will shorten service life.

You will find this material specified across automotive air conditioning, oilfield and downhole equipment, and heavy-duty powertrain.
