10 of these cartridges enough to pour about 30-50L beer and/or other liquids.
Each canister will carbonate approximately 3 litres of liquid to standard carbonation level for a soft drink / beer / cider etc.
Each CO2 canister will dispense between 3 - 5 litres of carbonated drinks from one of our mini keg systems. If you leave empty space in your keg you will use more gas (eg putting 5L of beer in a 10L keg will require flushing a lot more air out and then pressurising with CO2 than you would have to with 5L of beer in a 5L keg)
The thread is necessary for use with our mini regulators, unthreaded bulbs cannot be used.
These canisters are food grade bulbs that are threaded which fit on our mini regulator .
