Part number HS70365 is an AS568-365 green HNBR (Hydrogenated Nitrile) 70 Shore A O-Ring supplied with an inside diameter of 6.975 in (177.17 mm), a cross section of 0.21 in (5.33 mm), and an outside diameter of 7.395 in (187.83 mm). An o-ring remains the most cost-effective sealing element available for pressurized assemblies.

The compound resists petroleum oils and fuels, heat and oxidation, and ozone and weathering. HNBR (Hydrogenated Nitrile) is specified for the oil resistance of nitrile with substantially better heat capability, long service life in refrigerant and oilfield duty. Published continuous service range is -40°F (-40°C) to 325°F (162.8°C). It should not be specified for service in esters or chlorinated hydrocarbons.

Common environments for this compound include automotive air conditioning, commercial refrigeration, and engine timing systems.

Reference part number HS70365 when ordering; the item is sold individually. Nominal inside diameter is listed as 7 inch. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
