Soda Machine Co2 Adapter with High Pressure Stainless Steel External Hose, CGA320 Co2 Tank Direct Adapter to TR21-4 Soda Water Machine Compatible with Jet Aqua Fizz(36 inch)

So far so good! I was discouraged because the sodastream was to tight I could get a tool in the cavity to tighten the adapter. I was at harbor freight with a basin wrench trying to see if it would work when the quick release popped off...🤦🏼 It was then that I realized I could just use a socket. When I got home I used a 1 inch socket and was able to fit the wrench extension to tighten it even though it did fully attach because of the male end of the quick release. So don't get discouraged. Just make sure you have a 1 inch. If needed buy a deep socket from harbor freight. Because the hose is short, I'm going to have to drill hole in my countertop and hide it in the cabinet.This doesn't affect taste. The pressure is good. Ease of use was great once I figured it out my lack of knowledge. And it's very functional. I just wish that hose was longer so I could hide the CO2 tank a little bit easier.

===== UPDATE, May 2023 ======I was contacted by the seller via email, who graciously offered to replace the defective part free of charge! Customer service was prompt and friendly. They sent me a packet of replacement gaskets which fit perfectly now I'm back in business. They clearly go above and beyond to take care of their customers.===== ORIGINAL REVIEW ======Like other reviewers, mine started leaking...right after the 30 day return policy ended. I had to shut off pressure after each use, which nearly defeats the whole point of the valve.I was able to open the valve using a 6mm hex wrench, to confirm that the gasket inside the valve (on the stem itself) was cracked and crumbling. It was either very old, or subjected to harsh conditions of some kind, or poor quality, etc.Because I could not return it, I looked for replacement gasket. Unfortunately I could find no good alternatives, but I was able to make do with a cheap gasket out of a variety bag. It still leaks.

Works as described. Connects to the CO2 tank and to my Ninja Thirsti. Quick Connect adapter works well for taking on and off.

I am new to Soda stream and bought a Terra and Aqua fizz both at a great deal we found locally ;we like the plastic bottles and glass as well. After research and realizing the cost of replacing the soda stream cylinders was not going to work for us, i'm cheap and will find the least expensive and best quality option when applicable. So I did research on 5 gallon tanks and found an excellent one made by Vevor. They make great items at fair prices. Spend the money up front and continually save long term.This item works well and all the connections fit snuggly. So for now this is a great buy, hopefully it lasts.I hope this was somewhat helpful.

I grabbed this ("Older item fit Jet Aqua Fizz" style) to adapt a DrinkMate OmniFizz to a 20 lbs CO2 tank from my local gas supplier. It worked great for a month before the TR21-4 valve started leaking. When I removed the pin from the valve, the clear o-ring was badly damaged, dry, and cracked. It came off the pin in pieces! The orange o-ring shipped with this kit is not the correct size for this particular valve as seen in the photo, but the seller does have a style of this product called "O rings for black adapter" which I have on order. That style also includes a video on how to remove the pin and which part to replace. Otherwise, good metal parts, a nice quick connect for the hose, and I can't complain too much. At least it is serviceable.

Got this and had it sitting in a shelf until I used my sodastream cartridge. Installed this, connected easy made a few drinks. Went back a couple daysster to make a soda and nothing. Made sure the tank was open and connected and nothing. Like others, it leaked right out of the box. Because it's just been over 30 days I miss out on the return as well.

Family likes carbonated drinks. I bought this along with a 5lb. CO2 bottle. My local fire protection company refills “MY” 5lb.CO2 bottle for $20.00 v.s. 14oz $18.00 Sodastream bottle exchange. Huge savings!

I'm using this adapter with a 5lb tank and so far it's worked great. It was super easy to hook up (although you need a pretty large headed wrench to screw the adapter on the tank.) It seems to be relatively leak free but I also shut the tank after using so who knows.
