CO₂ cylinders for every fizz

The right fit for perfect bubbles​
Every Sodastream sparkling water maker is compatible with a specific cylinder type - either the Quick Connect Cylinder or the classic Screw In Cylinder. The right fit depends on your machine, but both deliver the same refreshing bubbles you love.
The Quick Connect Cylinder, with its pink handle, simply clicks into place - no twisting, no hassle. It’s the easiest way to lock in bubbles with a single motion. The classic Screw In Cylinder, marked with a blue seal, twists securely into the back of your machine. It’s reliable, sturdy, and just as effective at delivering consistent carbonation. ​
No matter which cylinder you use, each one is carefully sealed and tested to deliver the same crisp bubbles every time. That means reliable fizz you can count on.
Not sure which CO₂ cartridge fits your sparkling water maker? Use our cylinder guide to instantly find the right CO₂ cylinder for your soda maker and enjoy endless sparkle with total confidence.
