sulfur hexafluoride joints for testing

Sulfur hexafluoride (sf6 gas) or sulphur hexafluoride (British spelling), is an extremely potent and persistent greenhouse gas that is primarily utilized as an electrical insulator and arc suppressant. It is inorganic, colorless, odorless, non-flammable, and non-toxic. sf6 gas has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom.
