568-465 GREEN HNBR (HSN) 70 ORINGS

HS70465 is an AS568-465 green HNBR (Hydrogenated Nitrile) 70 Shore A O-Ring measuring an inside diameter of 17.955 in (456.06 mm), a cross section of 0.275 in (6.99 mm), and an outside diameter of 18.505 in (470.03 mm). In service, this o-ring delivers dependable bidirectional sealing in a compact groove envelope.

HNBR (Hydrogenated Nitrile) is specified here for oil resistance of nitrile with substantially better heat capability, excellent abrasion and tear strength. This material stands up to petroleum oils and fuels, sour gas and amine inhibitors, and ozone and weathering. Published continuous service range is -40°F (-40°C) to 325°F (162.8°C). Exposure to ketones or esters will shorten service life.

Maintenance and OEM teams specify it across automotive air conditioning, oilfield and downhole equipment, and engine timing systems.
