Fit for DUO/Terra/Art sparkling water maker
Can connect old soda water hose with TR21-4 male thread
Can make quick connection between soda water maker and Blue Co2 Cylinder
The Quick Soda Adapter is only compatible with the 60L Original Blue CO2 Cylinder that has a TR21-4 Male Thread. It's not recommended to use other cylinders from different brands. This is because if the blue CO2 Cylinder and its valve are not original, the Quick Soda Adapter may not screw down far enough to work with the new soda maker
