This co2 cartridge is used with larger, more robust mini regulators. One canister will push between 1-4 five gallon Cornelius style homebrew kegs, depending on how it is used and the CO2 consumption required.
Please Note: This unit is not compatible with the Torpedo Mini CO2 Regulator due to the gap between the threading and the tip of the cartridge. For those units select this link for the recommended 74 g cartridge.
