This easy to use SodaStream Cylinder Filling Adaptor will enable you to fill your own CO2 from your larger bulk cylinder into smaller SodaStream cylinders. An easy and inexpensive way to fill your own Sodastream Cylinders at home at a fraction of the cost of getting the refills from your local store.

When using, be sure to following these important points:

1. That the seals goes in the correct location. So when the SodaStream Filling Adaptor arrives, please make sure to use the correct seal in the correct side.

2. Make sure to put the Sodastream cylinder on the correct side. The SodaStream cylinder thread can actually fit both sides of this adaptor, but the CO2 cylinder only fit's into the ROUND SIDE. As a result you MUST put the Sodastream cylinder into the HEXAGONAL SIDE. (as show in image)

From our testing, if you try to fill a room temperature bottle you'lle get maybe a 1/3 filling (good enough to push out a keg of beer at a party). If you freeze yoru soda stream adapter over night you'll get closer to half.
If you want to fully fill your sodastream bottle, you need to freeze your sodastream bottle and turn your main bottle upside down during filling (we don't recommend doing that due to safe concerns!). Always wear safety gloves and safety goggles when filling.

Please note - this does not work with newer flat pin style (as in video below) sodastream bottles. Only works with older style raised pin sodastream bottles.
