oh, I'd not put the liquid into the lines, that could damage them! (-180F on rubber not a good thing!!!) but in liquid form, CO2 boils off like freon in the can, and the pressurized gas is perfect for pushing out the flush. it's also a good shield gas for welding!

do not invert the CO2 cylinder!!! DO NOT PUT LIQUID CO2 into your system!!! VERY VERY VERY VERY dangerous!!! 2000PSI is VERY VERY VERY BAD for any system!!! ONLY USE THE GAS for blowing out the lines!!! or REGULATED PRESSURE BELOW 200 psi to pressure test and mix with 4oz R22 for leak detection!
