HSN (HNBR) 80 568-120

APG stocks the HSN80120, an AS568-120 green HNBR (Hydrogenated Nitrile) 80 Shore A O-Ring measuring an inside diameter of 0.987 in (25.07 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 1.193 in (30.3 mm). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

HNBR (Hydrogenated Nitrile) is specified here for improved ozone and weathering resistance over standard nitrile, excellent abrasion and tear strength. It resists petroleum oils and fuels, sour gas and amine inhibitors, and heat and oxidation. Published continuous service range is -40°F (-40°C) to 325°F (162.8°C). It should not be specified for service in chlorinated hydrocarbons or strong oxidizing acids.

Common environments for this compound include oilfield and downhole equipment, heavy-duty powertrain, and engine timing systems.

HSN80120 ships individually. Unit weight is approximately 0.6315 g and nominal inside diameter is listed as 1 inch. Review your operating media and conditions against this specification before installation. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
