In this section you will find green gas and CO2 for your gas airsoft rifles and pistols.
Green gas can be referred to as HFC22 depending on where you are from. Overseas there is lower pressure gas such as HFC134a and some higher ones but for now we're going to talk about what is available in the US.
Green gas is the fuel used for gas blowback airsoft guns. It is a pressurized flammable gas that comes in a can. You would transfer the contents of the can into the magazine of your gas airsoft gun. Typically a 3 to 5 second charge is enough to fire the airsoft gun to completion. The nice thing about green gas is that you can always keep your gun topped off with gas at any time. Unlike CO2 which you are dealing with a small canister that has been punctured and you must use it all before you put in a new one. Green gas has silicone oil added to the mixture to help keep your seals from drying out from within your airsoft gun. On a gas airsoft gun the seals are the primary component that will require care more than anything.
Word of caution if you are using green gas: Do not puncture the can and do not inhale its contents. Use only in a well ventilated area. Green gas is toxic and flammable. Due to its pressurized nature, do not put a can out in direct sunlight on a hot day. The can may build pressure and eventually explode.
Green gas has a reasonable operating range for temperature but it is not recommended on cold days below 60 degrees F or you could expect sluggish performance. The chemical makeup of green gas is similar to that of propane so you can use them interchangeably if inclined. The main difference between green gas and propane though is propane being used in many things can be found in different pressure ranges. Also there is an added smell to warn humans of a dangerous gas leak. Propane lacks the silicone additive found in green gas so running propane in your airsoft gun could potentially dry out the seals sooner and you should add silicone oil yourself to supplement. Silicone oil is sufficient for airsoft guns so do not use something like WD-40 or gun cleaning compounds as those items contain petroleum which would be caustic on these o-rings.
Q: Can green gas guns use CO2?
A: CO2 is higher pressure than green gas. If you manage to somehow adapt CO2 to be fed into a green gas gun, it will not last very long due to the high pressure. CO2 guns are built stronger to handle CO2. However some makers have airsoft guns that are dual compatible which means it was built for CO2 already but have the option of a green gas magazine.
Q: How do I use propane?
A: Propane is an alternative to green gas (the chemical makeup is pretty much the same). There are adapters available from us that can add a fill valve to the commonly found camping propane tanks that you can get from many places.
Q: How do I lubricate my gas gun?
A: Apply silicone oil to the slide rails and any part that moves that makes contact with each other. You will also want to lubricate the O-rings and valves inside the magazine. To lubricate, simply apply a dot of silicone on the fill valve. Then fill the magazine for but a second pressurize it. The pressure will help disperse the oils to any leaky areas or to any seals it comes into contact with.
