HS70445 is an AS568-445 green HNBR (Hydrogenated Nitrile) 70 Shore A O-Ring with an inside diameter of 7.975 in (202.57 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 8.525 in (216.54 mm). In service, this o-ring compresses into its gland to block fluid or gas migration across a joint.

HNBR (Hydrogenated Nitrile) is widely chosen for excellent abrasion and tear strength, improved ozone and weathering resistance over standard nitrile. It resists ozone and weathering, modern refrigerants, and petroleum oils and fuels. Continuous operating temperature is published at -40°F (-40°C) to 325°F (162.8°C). Applications involving ketones or esters call for a different compound.

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