Perfect for simultaneously dispensing two kegs of beer at the same pressure, this Kegco product dual gauge two product CO2 regulator features a commercial-grade construction that has been specially designed to provide maximum convenience and durability in busy commercial environments like bars, tasting rooms, and restaurants. This double gauge regulator has a gauge on top that measures CO2 pressure in the kegs as well as a gauge on the side that indicates how much CO2 is left in the tank, so you'll never again be caught off guard by an empty CO2 cylinder. Both gauges come equipped with rubber boots that help prevent them from damage in the event of a fall, and a large pressure adjustment knob allows you to make quick and precise adjustments by hand. For added safety, this draft beer regulator features an internal safety pressure relief valve that releases when the delivery pressure gets too high, a manual pressure release knob that has been built into the regulator body, and two shut-off valves that make it easy to instantly shut off pressure to the kegs without backing up your beer lines. These shut-off valves have a check valve that prevents backflow into the regulator.
