Review on 🥤 Soda CO2 Refill Connector Adapter: PERA Household Cylinder Accessories – CGA320 to TR21.4 by Terry Kohl

Bought this to top up my carbon dioxide tank from my 5lb homebrew tank. It works well enough, but I also don't get a full charge in the soda flow tank. I can usually carbonate about ten liters of bottles before the pressure drops noticeably. Of course I have everything I need to refill it, so it's not bad, just a little annoying. A NOTICE. I've noticed that not all CO2 Sodastream tanks are created equal. If you look at the picture I uploaded, this will work on a tank with a small diameter pointed plug valve, but not a large diameter flat plug valve. It seems that the pressure is being distributed too much to the large spool valve to make it depress.
