Precautions：

If the inflation cannot be completed, Please check

• 【Inlet Thread】Filling adapter can be used to refill small CO2 tanks from larger CO2 tanks, the filling adapter is [US CGA-320(G1/2)], only suitable for the United States, Canada, not suitable for UK, Germany and other countries, if you are giving it as a gift, please make sure to be clear.
• 【Outlet Thread】The outlet thread for connecting the CO2 cylinder is TR21-4, which is suitable for most CO2 cylinders (not suitable for CO2 cylinders other than TR21-4 or clip-on design), especially not suitable for paintball tanks, As well as the latest sodastream Terraxi series water dispenser, they look similar, but the threads are not the same, they are not universal, please confirm before purchasing!
• 【Precautions】If the vial thimble is too thick and short to be inflated, the hose will expand, please replace the thin thimble bottle. The large cylinder should have sufficient pressure. If there is no siphon or liquid CO2 in the large cylinder, the CO2 atmospheric tank needs to be inflated upside down, please read the instructions carefully. Also, if you freeze the cylinders a few hours before filling, it will make filling easier and fill more gas.
