This is the most commonly used CO2 cylinder for topping up the pressure in homebrew beer barrels. Just screw the cylinder down onto the valve to start the gas flowing and turn it back it again to stop. The gas should be added to the keg in short bursts of 1 second to stop the cylinder freezing in the open position. Running the end of the cylinder under hot water prior to use will also help to prevent this.
These cylinders contain 245g of compressed Carbon Dioxide. Better value than a box of the CO2 Bulbs (approx 80 gms). Once empty simply bring it in & we will swap it for a full one at the refill price.
