568-135 GREEN HNBR (HSN) 70 ORINGS

APG stocks the HS70135, an AS568-135 green HNBR (Hydrogenated Nitrile) 70 Shore A O-Ring supplied with an inside diameter of 1.925 in (48.9 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 2.131 in (54.13 mm). An o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

It resists heat and oxidation, petroleum oils and fuels, and ozone and weathering. That behavior comes from the compound itself: 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.

It sees regular use in commercial refrigeration, automotive air conditioning, and oilfield and downhole equipment.
