HS70248 is an AS568-248 green HNBR (Hydrogenated Nitrile) 70 Shore A O-Ring with an inside diameter of 4.734 in (120.24 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 5.012 in (127.3 mm). In service, this o-ring compresses into its gland to block fluid or gas migration across a joint.
HNBR (Hydrogenated Nitrile) is specified here for long service life in refrigerant and oilfield duty, improved ozone and weathering resistance over standard nitrile. It resists modern refrigerants, heat and oxidation, and petroleum oils and fuels. Continuous operating temperature is published at -40°F (-40°C) to 325°F (162.8°C). Verify compatibility before use with chlorinated hydrocarbons or ketones.
Maintenance and OEM teams specify it across automotive air conditioning, commercial refrigeration, and oilfield and downhole equipment.
Stocked as HS70248 and sold individually. As always, verify media compatibility and operating conditions against the requirements of your specific application.
