568-153 GREEN HNBR (HSN) 70 ORINGS

The HS70153 is an AS568-153 green HNBR (Hydrogenated Nitrile) 70 Shore A O-Ring with an inside diameter of 3.487 in (88.57 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 3.693 in (93.8 mm). This o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

It resists modern refrigerants, ozone and weathering, and petroleum oils and fuels. HNBR (Hydrogenated Nitrile) delivers improved ozone and weathering resistance over standard nitrile, long service life in refrigerant and oilfield duty. Rated temperature range runs from -40°F (-40°C) to 325°F (162.8°C) in continuous service. Verify compatibility before use with strong oxidizing acids or ketones.

Common environments for this compound include heavy-duty powertrain, automotive air conditioning, and engine timing systems.
