A regulator to rule them all! The Ultimate CO2 Regulator by The Weekend Brewer is the last regulator you will need. With 5 input adapters and two output fittings, you will be able to use the regulator with nearly all other equipment you already own. Use it to carbonate homebrew and then attach the regulator using a grey disconnect and a CO2 cartridge (not included) to later dispense cold homebrew from the same keg! Use it with a carbonation cap and a SodaStream tank to carbonate homebrew in 2L bottles (our favorite carbonation method!), or attach it to a stainless steel mini-keg and dispense craft beer from your local brewery. Whatever methods you choose, the Ultimate CO2 Regulator Kit will do it flawlessly so you can get back to drinking! Choose from 2 different PSI ranges—0-25, and 0-50. 0-30 and 0-50 are both capable of force carbonating and dispensing.
