This o-ring is supplied in AS568-204 green HNBR (Hydrogenated Nitrile) 80 Shore A built to an inside diameter of 0.359 in (9.12 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 0.637 in (16.18 mm), catalogued under part number HSN80204. It compresses into its gland to block fluid or gas migration across a joint.

HNBR (Hydrogenated Nitrile) offers improved ozone and weathering resistance over standard nitrile, long service life in refrigerant and oilfield duty. This material stands up to sour gas and amine inhibitors, ozone and weathering, and modern refrigerants. Continuous operating temperature is published at -40°F (-40°C) to 325°F (162.8°C). Applications involving chlorinated hydrocarbons or strong oxidizing acids call for a different compound.

You will find this material specified across oilfield and downhole equipment, engine timing systems, and automotive air conditioning.

Order part number HSN80204, sold individually. Unit weight is approximately 0.4985 g and nominal inside diameter is listed as 3/8 inch.
