Review on 💨 CO2 Tank Refill Adapter Kit - CGA320 G1/2 Connector for Filling Soda Maker and Sparkling Water Maker Tanks by Michael Sharp

I connected this fitting to my CO2 tank which has a stem so it can dispense liquid in an upright position. Took me a few minutes to adjust the end valve as I believe it is the regulator. First the CO2 came in too fast and the 2-way valve blocked the port. I started by turning everything off and pulling out the cartridge and reinstalling it. When all the valves were tightly closed, I opened the tank valve about 1/4 turn. Then I opened the valve closer to the tank, then gradually opened what I think is the control valve, very slowly until I heard a hissing sound. Filling the frozen cartridge with liquid CO2 took a minute. It was full when the hissing stopped and the pressure equalized. When I started the frozen cartridge weighed 1lb 3oz, when filled it weighed 2lb 4oz which is the weight of a full cartridge. This valve really works, you just have to get used to the adjustments, after that it's a quick and easy process.
