568-246 GREEN HNBR (HSN) 70 ORINGS

HS70246 is an AS568-246 green HNBR (Hydrogenated Nitrile) 70 Shore A O-Ring with an inside diameter of 4.484 in (113.89 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 4.762 in (120.95 mm). In service, this o-ring compresses into its gland to block fluid or gas migration across a joint.

The material holds up against ozone and weathering, petroleum oils and fuels, and heat and oxidation. That behavior comes from the compound itself: HNBR (Hydrogenated Nitrile) is widely chosen for strong resistance to rapid gas decompression, excellent abrasion and tear strength. Service temperature is rated from -40°F (-40°C) through 325°F (162.8°C).

Common environments for this compound include engine timing systems, automotive air conditioning, and oilfield and downhole equipment.

HS70246 ships individually. Nominal inside diameter is listed as 4 1/2 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
