Sulfur Hexafluoride Gas for Sale

Sulfur Hexafluoride

Sulfur hexafluoride is a colorless, odorless, non-toxic and non-flammable gas with a vapor density five times that of air. It is also temperature-resistant up to 932°F, chemically stable and non-reactive under normal conditions and able to retain its gaseous form under high pressure (up to 250 psi). These unique properties give sulfur hexafluoride excellent insulation and arc-quenching capabilities.

At Meritus Gas Partners, we offer sulfur hexafluoride in a variety of purities and concentrations through our vast network of distributors. Contact a distributor near you to experience top-notch service from a partner in tune with your needs and dedicated to your satisfaction.

Uses and Applications of Sulfur Hexafluoride Gas

Sulfur hexafluoride gas has many applications across a variety of industries. 

Electrical Industry 

The majority of sulfur hexafluoride applications are in the electrical industry. Due to its high dielectric strength — almost three times that of air or oxygen — this gas effectively quenches electrical discharges, preventing arcs and short circuits in enclosed equipment. Some examples of gas-insulated equipment that use sulfur hexafluoride gas include:

  • Switchgear
  • Circuit breakers
  • Transformers
  • Disconnectors and ground switches
  • Capacitors
  • Gas-insulated lines and substations

Medical Industry

In ultrasound imaging, sulfur hexafluoride gas is used as a contrast agent, improving the clarity and quality of sonograms. It is also used in ophthalmology to perform vitrectomy — a procedure that treats issues with the retina and vitreous. During this procedure, sulfur hexafluoride may be used to fill the void left after removing the vitreous.


Sulfur hexafluoride’s non-reactive nature makes it ideal for magnesium casting processes. It protects molten magnesium from oxidation. Manufacturers may also use sulfur hexafluoride for etching due to its high density and large molecular size to produce semiconductors. 

Sulfur Hexafluoride Gas Safety

While sulfur hexafluoride is non-toxic, its inhalation is still dangerous since it displaces oxygen from the lungs and may lead to asphyxiation when inhaled in large amounts. Specific safety measures are recommended to mitigate potential risks to individuals and the environment. For instance:

  • Ventilation: Ensure proper ventilation in areas where sulfur hexafluoride is used to prevent accumulation. 
  • Storage: Store sulfur hexafluoride cylinders in a cool, dry area away from ignition sources and direct sunlight.
  • Personal protective equipment: Wear appropriate protective gear including gloves, safety goggles and protective clothing when handling sulfur hexafluoride.
  • Training: Educate personnel about the properties, risks and safe handling procedures of sulfur hexafluoride gas.

Environmental Impact and Regulations

Sulfur hexafluoride is recognized as a potent greenhouse gas with a global warming potential significantly higher than other greenhouse gases such as carbon dioxide. Its use and handling are subject to strict international and local regulations aimed at minimizing emissions and encouraging recycling. Meritus Gas Partners is committed to environmental stewardship. We advise clients on the best sulfur hexafluoride recycling and disposal practices to align with regulatory requirements and reduce environmental impact.
