Kegco's new HL-62 Commercial Grade Dual Gauge CO2 Regulator has been specially designed to deliver maximum convenience and durability in hectic commercial environments like bars, tasting rooms, and restaurants. This double gauge draft beer regulator has a gauge on top that measures CO2 pressure in the keg as well as a gauge on the side that indicates how much CO2 is left in the gas tank, so you'll never again be caught off guard by an empty CO2 cylinder. Both gauges come equipped with rubber boots that help protect 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 regulator also features an internal safety pressure relief valve that releases when the delivery pressure gets too high, a manual pressure release valve built into the regulator body, and a shut-off valve that makes it easy to quickly shut off pressure to the keg without backing up your beer line. This shut-off valve has a check valve that prevents backflow into the regulator.
