568-353 GREEN HNBR (HSN) 70 ORINGS

Ordered as HS70353, this is an AS568-353 green HNBR (Hydrogenated Nitrile) 70 Shore A O-Ring measuring an inside diameter of 4.975 in (126.37 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 5.395 in (137.03 mm). The o-ring compresses into its gland to block fluid or gas migration across a joint.

The compound resists ozone and weathering, petroleum oils and fuels, and modern refrigerants. HNBR (Hydrogenated Nitrile) is known for improved ozone and weathering resistance over standard nitrile, the oil resistance of nitrile with substantially better heat capability. Rated temperature range runs from -40°F (-40°C) to 325°F (162.8°C) in continuous service. Applications involving ketones or chlorinated hydrocarbons call for a different compound.

You will find this material specified across oilfield and downhole equipment, automotive air conditioning, and heavy-duty powertrain.
