CO2 Canisters (Bulbs / Cartridges) | 16g Threaded | 10 Pack

Size Guide


CO2 cartridges delivered to the door, the more you buy the cheaper they are!

Usually about $3 - $4.50 if bought singly (for instance at bicycle shops which sell them for use in tyre inflators)

They start at $2.50 each in a 10 pack from us and going down to $1.60 each if you buy a carton of 300 bulbs.

These CO2 canisters are medical / food grade unlike the ones from bike shops which may contain traces of oil and grease that can contaminate your drink. 

Each canister will carbonate approximately 4 litres of liquid to standard carbonation level for a soft drink / beer / cider etc.

Each CO2 canister will dispense between 4 - 6 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.
