That is a pretty damn handy link. I think I will still prefer the AI adaptor, but that looks like a fantastic alternative and I think I will have to try it, even if just for fun.

Haha, I like that article.

Unfortunately the 134a source they're using is available only in the US. I considered developing an adaptor for automotive AC cans, but they're not here in Canada. They're also predosed with lubricants and line cleaners for car AC. I'm not sure if they're compatible with airsoft materials as they're not silicone oil.

Hey fellas im in australia and im having trouble working out what is exactly in these gas dusters (Tetrafluoroethane, 134a)

I have a can called "dust away" which describes the propellant as hydrocarbon and i think is the right composition. Another can called CO cleaner whose propellant is carbon dioxide. What is this stuff lol. I assumed that they use the same gas in these component cleaners in this country but who knows what theyre putting in it?

I just found out hydrocarbon is Liquified Petroleum Gas (LPG), propane, butane, Propylene, or a mixture of propane and butane, depending on the seasons

carbon dioxide is used in some airguns and paintball guns

so yeah look carefully at what is actually in your gas duster

Carbon dioxide is CO2. Propane can be used in gas guns (also called Green Gas). Read some more, it's been discussed to death.
