A CO2 regulator is used to have a fine control over the amount of CO2 being dispensed to your beer (typically 8-15 psi). They have adjustable output pressure and many have safety valves and auto-shutoffs as well as a safety precaution. The gauges will show either the pressure of the tank itself, or the output pressure, depending on the type of regulator. You can also use them in the process of force carbonating. We also stock nitrogen regulars for cold brew coffee and beer styles like stouts. For all the various setups, we sell a variety of regulators made by top brands like Taprite.
