This mini-regulator is the best out there for providing accurate CO2 pressures with ease of portability. This is a two-stage regulator, meaning it drops pressure from 800 psi down to a lower pressure, then drops to the set serving pressure. This offers rock-solid serving with no variation through the lifespan on the keg. Regulator gauge features 0-30 psi, and includes a ball lock gas quick disconnect. Uses a 74 gram CO2 cartridge, which can push up to 2 five-gallon kegs.
