CO2 Tank Power Filler Transfill Tool from Power Tank. During competition our competitors running our Jet Paks often need to refill or top-off their little 20 oz. bottles with CO2. Up until now this tool, called the Power Filler, was only available to them as a custom built tool. Now you can have one too.
For the construction industry this handy tool allows you refill your Sidearm bottles at home or on the job site from a 10-50 lb. CO2 mother tank.
Note: You will have to invert your mother tank or get one with a siphon tube installed.
