HSN (HNBR) 80 568-280

APG stocks the HSN80280, an AS568-280 green HNBR (Hydrogenated Nitrile) 80 Shore A O-Ring supplied with an inside diameter of 13.984 in (355.19 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 14.262 in (362.25 mm). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

The compound resists ozone and weathering, modern refrigerants, and sour gas and amine inhibitors. That behavior comes from the compound itself: HNBR (Hydrogenated Nitrile) offers long service life in refrigerant and oilfield duty, improved ozone and weathering resistance over standard nitrile. Continuous operating temperature is published at -40°F (-40°C) to 325°F (162.8°C). Exposure to strong oxidizing acids or esters will shorten service life.

You will find this material specified across automotive air conditioning, heavy-duty powertrain, and commercial refrigeration.

Reference part number HSN80280 when ordering; the item is sold individually. Nominal inside diameter is listed as 14 inch.
