Box of 24 N₂O (Nitrogen) Cartridges

Nitrogen cartridges can be used in the Tap-A-Draft system to dispense a creamy, Guinness-like head on a beer. Use 1 nitrogen cartridge with 1 CO2 cartridge for best results. Works only with the old style Tap-A-Draft System.

Note: Nitrogen cartridges only work in the Tap-A-Draft system.
