This is because of some tanks have not the dip tube (syphon tube) inside. - pin not included. If needed,please use pin or wrench to Open the vent screw to discharge the residual gas. - NOT compatible with donor tank that has a residual pressure valve. SODA CO2 REFILL ADAPTER - This easy-to-use Cylinder Filling Adaptor will enable you to fill your own CO2 from your larger bulk cylinder into smaller cylinders. - An easy and inexpensive way to fill your own Cylinders at home at a fraction of the cost of getting the refills from your local store. - Can be used with large CO2 tanks with CGA320 connector ( the USA, CAN, Brazil, Colombia) SPECIFICATIONS Material: Brass Size: 2.2x2.2x6cm Packing included: 1 x CO2 Refill Adapter TR21-4 to CGA320 Connector 4 pcs Big Gasket and 4 pcs Small Gasket How it works 1. Cool the Soda-Strean Cylinder in the freezer for 1 hour. 2. Screw the adapter to a commercial CO2 gas cylinder. 3. The empty CO2 cylinder is screwed into the adapter. 4. For most big cylinders: turn the big cylinder upside down. (if you can not refill when the CO2 tank standing, because some of the tank have not the dip tube (syphon tube)inside.) 5. Carefully Open the valve of the large gas bottle(The valve on the Soda-Strean Cylinder closes the flow if it is opened too much. This will happen if you open the big cylinder too much / too fast. The trick is to open the big cylinder very carefully. You will hear the airflow. So to fill it successfully). 6. After about 15-20 sec., The cylinder is completely filled. 7. Close valve of the large gas bottle. 8. Opening the bleed screw to drain residue remaining gas. 9.Unscrew the CO2 cartridge – done.

Easy to use, no problem, i recommend watching some videos before attempting to do it and wear gloves and glasses if not sure what youre doing this isnt idiot proof. Freeze your canisters before filling.

Great price and extremely easy to use... just have to open the valve slowly whit the tank up side down to get the liquid out to refill the bottles, you do not want the gas to fill the bottle, so far filled 2 bottles without a hiccup, bottle actually seem to get filled more than when you purchase them new, I felt them heavier than when replaced by Sodastream. A refill of a 5Lbs CO2 tube is $15 ($25 for a 20Lb), you can fill at least 5 of the small bottles with the 5Lbs, it pays itself off very fast if you use your soda machine as I do.

Not much to say about this, it feels strong and solid, and fills my carbonation machine bottles simply and easily. The only thing I would like to see improved in the design is an internal lip or catch to keep the ring gasket seated in place. When a bottle is not attached it can fall out, but this doesn't affect the usability of the device, just the ease of use. Overall great product that will save an enormous amount of money compared to exchanging bottles.

The round o-ring on the big tank side works well and forms a good seal. The flat washers, for the drink tank side, is too thin to form a seal so I wound up just putting both flat washers in there to get it to work and will look for a thicker one at some point. The bleed screw is horribly designed and should not be used. I blew the super-tiny o-ring the few times I tried using the bleed screw so I stopped using it. I found it was just easier to unscrew the tank and released the pressure that way. On the drink tank side, there is a valve depression point that can be adjusted or removed. Adjusting it is very easy, and it may need additional adjustments if it moves in or out over time. Given all that, I'm able to fill the tanks full each time and check the weights with a scale. All my drink tanks are the anti-fill type but when going slow they all fill properly. I don't empty the drink tank before filling, if done properly there's just no need. Please secure any big tanks, wear gloves, eye protection etc and use in well ventilated space.

This didn't work for me until I put the sodastream canister in the freezer for a few hours beforehand, then filled it with my CO2 tank upside down. After that it worked like a charm. I just wish the instructions had suggested this

Had previously bought: https://www.amazon.com/gp/product/B089GXJ3T3 ... this is so much simpler (less clumsy), and the hoses on the other side quickly deteriorate and leak... this is much simpler and less expensive... EXCEPT FOR THE BLEED SCREW. It was leaking, so I tightened it, and it broke off. Don't use the bleed screw to release pressure, just unscrew the sodastream bottle (carefully). There's not a lot of trapped gas to release in this design.I used both sodastream bottles with refillable and unrefillable end caps... from my previous experience, I knew "get as much as you can into the unrefillable style, and be happy with what you get".I did see in one one video: freeze the empty bottle prior to refilling. Good idea.Another video said this comes without a pin needed to fill the bottle, and they used a screwdriver on the end... with no explanation. I'm not following this, nor know what the pin that not's included is referring to., The bottles seemed to fill correctly anyway.

EDIT:I left the positive review below a few months ago, but now have to revise downward for one simple reason. The metal used on the relief valve thumbscrew is utter garbage. After only a few months of use, the head completely sheared off while hand tightening this valve, leaving the unit useless. Looking at the broken off edges, it appears to be cast form extremely low grade, weak, pot metal. A pity, too, because the brass connector itself appears quire well made.Dropping this to one star and recommending you look somewhere else, as this unit just won't hold up.ORIGINAL REVIEW:I picked up one of these to fill classic Soda Stream CO2 tubes from a 10lb tube I use for a kegerator setup, and so far it has worked out quite well. It's machined from solid brass and is quite effective if you know what you are doing. I'd give this five stars, but the o ring on the relief valve was installed incorrectly, so it leaked out of the box. Luckily, it included multiple replacement O rings, so it was an easy fix.Some use tips:1. Your Soda Stream tube MUST be at freezing temperatures in order to fill properly. This is because the pressure CO2 is liquid and will gassify as it hits the warm tube, preventing a full fill. I put mine on ice about an hour before filling for best results.2. Point your source cylinder DOWNWARD while filling, which will allow the CO2 to flow into the Soda Stream tube.3. Open the valve on your source canister slowly, until you hear the gas flowing. The Soda Stream tube has a lockout on the pin that will prevent the flow if you open the valve too quickly.4. After you've filled your Soda Stream tube, close the valve on your source cylinder, and turn the relief valve on the coupler to vent excess gas. This will make it a lot easier to remove the coupler.5. Since this is an unregulated coupler, this will fill until the pressure on each side is equalized. Therefore, your best fills will come when your source tube is full. If you are filling from an emptier cylinder, your Soda Stream tube will not fill fully.
