Our Economy Series Primary Beer Regulator for Home Draft Dispense is easy to use and easy to maintain. The set screw adjustment makes it a "set and forget" tool for maintaining constant pressure into your system. The regulator's brass body and zinc bonnet make it corrosion resistant and highly durable in a number of environments. This 1 Pressure 1 Product Regulator has a CGA320 Inlet, 5/16"Barb Shutoff w/Check, and 60lb and 2000lb Gauges so you can see both your output pressure and how much CO2 is left in your tank.
