The Soda Maker CO2 Fill Device is compatible with every CoolFire Trainer Barrel and works with Soda Maker CO2 Tanks. It screws directly onto the CO2 Tank to allow re-filling of the CoolFire Trainer Barrel.
Purchasing a CoolFire Trainer Barrel and CO2 Fill Device together results in a $10 discount at checkout!
IMPORTANT: A CO2 Fill Device is needed to make the CoolFire Trainer function. If you do not already own a CO2 Fill Device, please choose one from our selection of CO2 Fill Devices.
