Low‑pressure single‑body regulator with John Guest

Single-body low-pressure regulator with John Guest for CO2 gas cylinder

For professional beer service, choose the low-pressure primary regulator with John Guest. Ideal for maintaining perfect carbonation and service with multiple dispensing taps. Ideal for cold rooms and towers with multiple taps.

Primary regulator* or low‑pressure gauge that regulates the pressure coming from the gas cylinder (high‑pressure source) and connects to the beer keg, attaching to the keg valve (reducing the pressure). When a pressure is recommended, it is usually specified.

Easy installation on cold room panels (store and dispense beer kegs). As many as needed are connected in series to supply the different kegs.

The gas regulator contains a manual adjustment screw or knob to regulate the amount of pressure supplied to the keg.

The gas regulator is vitally important for maintaining the correct CO2 level in beer. Too much CO2 can add excess CO2 to the beer and cause foaming and over-carbonation issues, while too little CO2 pressure can release the CO2 from the beer itself, resulting in flat beer with little or no gas/head.

*A high-pressure regulator connected to a CO2 cylinder is required to feed this low-pressure regulator.
