Kegco's LHU51 Elite Series Single Gauge CO2 Draft Beer Regulator has a bold design with elite functionality. Designed for applications where one keg of beer will be dispensed at a time, it has a large adjustment knob that is easy to grip and turn for precise pressure placement. It features a single 5/16' barb and a single gauge that indicates how much CO2 pressure is inside of the keg. For added safety, this regulator has been designed with a manual pressure release valve and an internal pressure relief valve that releases pressure at 55-65 PSI. A sintered metal filter has been built into the stem to keep harmful contaminants out of the regulator, ensuring long-lasting efficiency for beers and beers to come.
