Helium gas – also known as balloon gas – is inert, non-flammable, colourless, odourless and tasteless. Useful for a range of purposes such as inflating balloons, you can buy helium gas tanks and cylinders from dedicated providers like Supagas.
Supagas offers a range of helium cylinder sizes: CL size (0.6m3), D size (1.2m3), E size (3.5m3), G size (9.1m3) and 12 Pack (153m3). You can hire a new cylinder, get a helium refill or dehire a depleted cylinder.
Helium gas can be used for:
- Balloon inflation
- Welding gas mixtures
- Gas chromatography
- Glass production
- Leak detection
- Heat transfer
- Gas lasers
- Medical gas mixtures
- Scientific research
- Purging gas for metallurgical processes

FAQs
Where can I buy helium gas?
If you’re wondering where to buy helium, you can rent and exchange helium gas cylinders at a wide selection of Supagas locations right around Australia. Supagas has been your local gas supplier since 1968, and we pride ourselves on exceptional delivery and customer service.
How is helium stored?
At Supagas, we capture the boil-off of liquid helium and then recycle and compress the lower-grade helium into small storage cylinders, which become part of our balloon gas supply.1 You can find a variety of sizes of retail helium cylinders here.
How long does a helium cylinder last?
Helium does not expire nor degrade. As long as the valve is sealed air-tight, the helium in the gas cylinder won’t escape.2 If you are using the helium cylinder to blow up balloons, you can generally expect them to last according to their container size:
- CL size (0.6m3): 50 balloons
- D size (1.2m3): 100 balloons
- E size (3.5m3): 300 balloons
- G size (9.1m3): 800 balloons
Is helium flammable?
No. Helium is an inert, non-flammable and non-combustible gas.
Is helium poisonous?
No. Helium is an inert gas and not poisonous. However, it is dangerous to inhale helium because it deprives your body of oxygen. Essentially, every time you inhale helium it takes more oxygen out of your system, which can cause your body’s oxygen level to fall to dangerous levels very quickly.3
