Has anyone direct experience with transferring liquid carbon dioxide from one cylinder to another?. I'd like to transfer the contents of a 6Kg cylinder to another one. I understand the source cylinder is upside down and uphill of the receiving cylinder and you connect the two valves with suitable high pressure line of 1000 PSI working pressure and open both valves. What I'd like to know: does the liquid CO2 just run downhill into the receiving cylinder to get a full transfer of the liquid gas?. I've made some custom fittings for the Australia only "Type 30" food grade CO2 fittings: 0.860" 14 TPI to adapt to 1/4" tube 20 TPI brass 45 degree flare fittings and I plan to use 1/4" soft copper tube which has a working pressure of about 1900 PSI (CO2 is about 850-1000 PSI). The plan is to have the receiver cylinder out of sight around a concrete wall with the valve open and crack open the source cylinder valve.
