568-207 GREEN HNBR (HSN) 70 ORINGS

Ordered as HS70207, this is an AS568-207 green HNBR (Hydrogenated Nitrile) 70 Shore A O-Ring supplied with an inside diameter of 0.546 in (13.87 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 0.824 in (20.93 mm). The o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

This material stands up to modern refrigerants, ozone and weathering, and petroleum oils and fuels. That behavior comes from the compound itself: HNBR (Hydrogenated Nitrile) delivers the oil resistance of nitrile with substantially better heat capability and strong resistance to rapid gas decompression. Continuous operating temperature is published at -40°F (-40°C) to 325°F (162.8°C). Applications involving ketones or strong oxidizing acids call for a different compound.

Typical settings include engine timing systems, automotive air conditioning, and commercial refrigeration.

This item is sold individually under part number HS70207. Nominal inside diameter is listed as 9/16 inch. Application requirements vary, so validate compatibility with your process conditions prior to installation. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
