# Best CO2 Regulators for Homebrew Kegging (2026) Source: https://homebrewcraft.com/best/co2-regulators Updated: 2026-09-14 Publisher: Home Brew Craft. Our score is an editorial rating out of 10 (fit 35%, features 25%, build 20%, value 20%), not a customer rating. Method: https://homebrewcraft.com/how-we-research#our-score A CO2 regulator is the control panel of your draft system, stepping tank pressure down to a serving or carbonation level you can trust. Look first at the gauges: one reads the pressure going to your keg, and a second reads how much gas is left in the tank so you are not caught empty mid pour. Build quality shows up in the diaphragm and the shutoff valve, and a good check valve stops beer from creeping back into the body. If you plan to run more than one keg at different pressures, a secondary regulator or a multi body unit lets each line sit where it belongs. A single keg brewer is well served by a solid primary regulator with a clean shutoff. Brewers running several kegs, or mixing styles that need different carbonation, should step up to a body that splits into multiple outputs. Check that the inlet matches your CO2 tank thread and that the outlet fits your gas line. Set it, watch the gauge settle, and you can walk away knowing your carbonation will land where you set it. ## Picks ### 1.
