CO2 Tank Power Filler II Transfill Tool from Power Tank. Need to refill or top-off your little 20 oz. bottles with CO2? Now the Power Filler II is available. This tool allows you to refill your 20 oz. at home or on the job site from a 10-50 lb. CO2 mother tank. CGA-320 valve to CGA-323

The 36 in. hose makes it easier to weigh your 20 oz. bottle on a scale as you fill to make sure you don't under or overfill your bottle.

Note: You will have to invert your mother tank or get one with a siphon tube installed. You can mount one of our 10/15 brackets to a location of your choice for a safe way to invert your mother tank.
