This o-ring is supplied in AS568-464 green HNBR (Hydrogenated Nitrile) 80 Shore A supplied with an inside diameter of 17.455 in (443.36 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 18.005 in (457.33 mm), catalogued under part number HSN80464. It compresses into its gland to block fluid or gas migration across a joint.
HNBR (Hydrogenated Nitrile) is valued for excellent abrasion and tear strength, improved ozone and weathering resistance over standard nitrile. Expect good resistance to ozone and weathering, petroleum oils and fuels, and heat and oxidation. Published continuous service range is -40°F (-40°C) to 325°F (162.8°C). Exposure to ketones or esters will shorten service life.
It sees regular use in automotive air conditioning, commercial refrigeration, and oilfield and downhole equipment.
HSN80464 ships individually. Check the compound against your process media, pressure and temperature before committing to a design. Not finding the exact configuration you need? APG cross-references from prints, samples and competitor part numbers.
