This adapter lets you fill Sodastream® C02 tanks with any 5 pound or larger C02 tank with a standard CGA320 valve (like the type used in draft beer systems). Save a lot of money compared with buying small Sodastream cylinders. Fits all screw on (not quick release) Sodastream C02 tanks.
Note that newer Sodastream cylinders have an valve that makes it harder to refill them as shown in the picture above. To see more about this on the video below, skip to 4:50 in the video. They must be filled very slowly to avoid having the gas pressure shut off the valve.
NOTE: You must have internet access in order to access the video directions to safely use this product, so do not order this product if internet access is not available where the product is to be used (video directions are below).

Q: Since there is no gauge on this adapter, how can you tell when it is full? Assuming I freeze it and I purge the empty tank completely, does the fill process stop when it's full? Can it be overfilled or become dangerous? I assume the pressure will equalize. So it shouldn't, right?
A: You will need a gram scale. A full Sodastream cylinder weighs 1164 grams, and an empty one weighs 760 grams. So fill it and weigh it until it gets to 1164 or is close to 1164 grams. Be careful, it you overfill, it can be dangerous. See our item Ill for a suitable inexpensive gram scale.

Q: Do you sell the replacement washers? They are hard to find and we've used them all up! Thanks!
A: Yes, see our item B68

Q: When I try to fill up the soda stream with the adapter, most of the air leaks from the silver knob on the adapter. How do I prevent the air from escaping there?
A: Check out the pictures on our webpage for Z50 and compare it to the Soda Stream bottle you have. I suspect you have the new design. If so you must fill the bottle slowly. Try opening the valve on your Co2 bottle slowly and only partially and that should solve the problem.

Q: My CO2 cylinder has a QF-35C valve. Do you have an adapter compatible with this valve?
A: No, we do not have an adapter, this only fits a CGA320 C02 valve.
Perfect
The adapter works perfectly and has made it soooo easy to refill our Aarke carbonator from home and a significantly reduced cost!
Just Works
I was skeptical that it would work given its simplicity and lack of a regulator. But it is simplicity itself and it just works. My only reservation is that the valve adjustment is a little stiff and hard to set to minimum flow that the refill of Sodastream canisters needs.
Fills my soda stream tank
Does what it’s supposed to. My first tank I only got 200g in. The second I was able to fill all the way. It seemed important to freeze the empty tank for a few hours to get it really cold. Measure your empty and full tank to get an idea how close you get too. My empty soda stream tanks are 7-8hundred grams. When full, it usually weighs 1150-1200g
Doesn’t work
I’m pretty handy and tried every way possible and got nothing in my tank with this adapter. Don’t waste your $.
This is a game changer
Super fast delivery, and this thing works like a charm! We had two older Sodastream canisters with the small valve so it filled up in a few seconds. The component seems to be made of super durable material. Amazing. Thank you!
