Sodastream Cylinder Adapter

Use a Sodastream cylinder to dispense/carbonate
your kegs. This is the ideal unit for the low volume user, or someone who does not want to put a lot of capital into purchasing a larger CO2 Cylinder. The adapter fits between the soda stream cylinder and the CO2 Regulator as shown in photo above.
Soda stream cylinder adapters are also great for small portable keg setups.
