Review: Refill VERY Slowly to make it work - So this works well on the old blue style SodaStream CO2 canisters BUT when you open the CO2 valve to fill you have to crank it open 1 mm at a time VERY slowly until you hear the CO2 going into the bottle and then stop cuz it only refills if you go super super slowly and it takes a couple minutes for it to refill but you can hear it. If you open it even a little more it will stop due to the safety valve and then you'll have to start over by closing the tank valve and then releasing the adapter pressure and then tightening the adapter pressure knob and then once again open the CO2 canister super duper slowly like amazingly slow until you hear the flow. Also there is a brass filter in there that originally I thought was blocking the flow but it's just a filter. I poked it out with a screwdriver. You can pop it out or leave it in it's supposed to filter impurities from your CO2 source Also I froze the canister overnight and I now have a full pound filling the CO2 canister. It's even more C02 than you get directly from SodaStreams canisters 🤠 Review: So far so good - Looked and researched a lot of bees found a lot of good videos to help explain things and this one fits the bill perfectly for me. I’ve been using it for three refills with no problems whatsoever. ## Features - 🌟Compatible Model:The CO2 adapter only replacement for CGA320 to TR21-4(Not applicable to CO2 tank with W21.8-14 joint) - 🌟Easy to Install:The CO2 adapter connector kit is very easy to use, and the adapter is easy to tighten with empty CO2 cylinders.You can install it correctly according to our picture - 🌟Quality Assurance:High-quality materials have a longer service life and are durable.Good air tightness, no gas leakage when connected to the cylinder, more convenient to use - 🌟Pakacge Include:You will get 1*CO2 adapter and 8*O ring(In order to ensure the tightness, the O ring is designed to be slightly larger than the installation opening, so it needs to be pressed hard to install.）Note: RPV pin not included. if your donor tank has a residual pressure valve (if so, RPV pin is require). - 🌟After-Sales Service:If you have any questions about the our product, please feel free to contact us.

I’ve been using it for three refills with no problems whatsoever. ### ⭐ Hard to use just buy the kit and use direct from the big bottle. *by D***S on May 8, 2026* This is honestly a waste of money and time. I had a hard time filling the bottles. Often times not getting the full load or none at all, but just a bit of co2 spray not the liquid. As you want the liquid to make the soda stream work. What worked so much better is the kit to connect a standard co2 tank found at a local brewing supply store. In this case you don't want the tank with the straw just a 5 lbs tank and no straw that you would need for this adaptor any how, if your invertering it. Anyone want to buy this and the bottles as I'm done with this mess. ## Frequently Bought Together - Soda Refill Bottle Co2 Adapter Refills Connector Kit for CGA320 to TR21-4,Soda Machine Soda Bottle Adapter Connector Adapter Accessories Replacement for (CGA320 to TR21.4) - 20 lb CO2 Tank New Aluminum CGA320 with SIPHON TUBE by Beverage Elements - Soda Machine CO2 Cylinder Refill Adapter Hose Soda Maker Co2 Canister Refill Station for Filling Soda blue Co2 Bottle --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tw/products/604389466-soda-refill-bottle-co2-adapter-refills-connector-kit-for-cga320](https://www.desertcart.tw/products/604389466-soda-refill-bottle-co2-adapter-refills-connector-kit-for-cga320) --- *Product available on Desertcart Taiwan* *Store origin: TW* *Last updated: 2026-10-22*
