Monkemon Upgrade CGA320 to TR21-4 Soda maker Co2 Tank Cylinder Direct Adapter with 60 inches High-Pressure Hose, Soda Maker direct Connector for sodastream, Soda Club (Gauge and bleed valve)

I have to admit I was pretty skeptical. I have one of the first and simplest Sodastream makers (canister holders) and figured there might be some serious issues retrofitting an old but full CO2 canister a friend cast off from a defunct keg fridge. Didn't I need a regulator? Was this going to blow the seals? was that hose going to be strong enough? After using this for several months I can say that this is everything you need. No regulator needed - the gauge shows a constant near 1000 psi. I cut a notch in the bottom of my Sodastream to accommodate the hose through the base and it works great. In the first month I had a couple issues with some kind of back-pressure, but there is a bleeder valve near the pressure gauge, so it's easy enough to cure. Really no issues since then. Maybe eventually this setup will kill the seals, but so far, in savings it's paid for itself, and a replacement Sodastream base if it comes to that. Update: was having an issue again with not getting CO2 through the nozzle, so I went through the process of tearing everything down to see if there were issues with the seals. After looking at how the entire system is designed, I wound up resolving the issue by running a small needle through the end of the nozzle that injects into the water bottle to dislodge some piece of debris that found its way into the system. This is something that could happen even with the regular bottle exchange - and is perhaps even more likely with more frequent changes. After examining the connections and essentially very simple design of the system, I can say with a fair amount of confidence that you would be extremely unlikely to have "seals" fail (and that cleaning a blocked nozzle is something that can be done without tearing down the entire system). If the bottle is over-full, you can get some leakage through the pressure seal especially on the first injection, but after air drying between uses, it's an occasional minor annoyance that is easily prevented by either not exceeding the fill line or using a more gentle press on the first injection.

me gusto bastante, la manguera es muy delgada pero se ve muy resistente se le nota el trenzado metálico para aguantar la presión del tanque de Co2

WONT WORK IN AUSTRALIA. THEY SHOULD HAVE THAT ON THE PRODUCT AND THEY DONT!!! Absolutely useless. Just try to connect it up for the first time and it won’t even connect. What a waste of money. DONT BUY! It won’t even screw on to the co2 bottle I bought from keg land. Just buy one from them.

Die Verbindung zur Flasche (Kohlensäure ) ist nicht aufzuschrauben .Gewinde defekt

I've waited a long time for this, the price was finally right to pull the trigger and ordered it so I can finally get my sodastream running again. 5lb tank with this adapter works marvelously, even comes with two spare gaskets which you may need down the future so don't lose them. Just make sure the hose end to the 5lb tank is snug with an adjustable wrench or else it will leak out when you open the tank. The gauge on the side is great and gives an accurate reading of just under 900psi
