568-272 GREEN HNBR (HSN) 70 ORINGS

Ordered as HS70272, this is an AS568-272 green HNBR (Hydrogenated Nitrile) 70 Shore A O-Ring with an inside diameter of 9.484 in (240.89 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 9.762 in (247.95 mm). The o-ring compresses into its gland to block fluid or gas migration across a joint.

HNBR (Hydrogenated Nitrile) is known for strong resistance to rapid gas decompression, excellent abrasion and tear strength. The compound resists ozone and weathering, sour gas and amine inhibitors, and modern refrigerants. Published continuous service range is -40°F (-40°C) to 325°F (162.8°C). Verify compatibility before use with ketones or chlorinated hydrocarbons.

Typical settings include engine timing systems, automotive air conditioning, and oilfield and downhole equipment.

HS70272 ships individually. Nominal inside diameter is listed as 9 1/2 inch. Check the compound against your process media, pressure and temperature before committing to a design. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
