Sulphur Hexafluoride (SF6)

Sulphur Hexafluoride (SF6) is an inorganic, colourless, odourless, non-flammable, extremely potent greenhouse gas, and an excellent electrical insulator. SF6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulphur atom. It is a hypervalent molecule. Typically for a non-polar gas, it is poorly soluble in water but quite soluble in non-polar organic solvents. It is generally transported as a liquefied compressed gas.

Packaging Information







  • Available from A‑Gas - find your local distributor for further details
  • Store cylinders in a cool, dry, well-ventilated area, out of direct sunlight
  • SF6 allows simplified design of high and medium voltage switchgears because of size and weight reduction, quiet and reliable handling, and maintenance
  • The emission of one kilogram of SF6 can be expressed as equivalent to 23.5kg CO2 emissions (=38 car emissions per year) 
  • Empty cylinders are to be returned to A‑Gas
  • For alternative or larger package sizes please contact A‑Gas on 1800 002 427 or via the Contact Us form
