Kegco's LHU52 Elite Series Dual 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 boasts a double gauge design that displays both the CO2 pressure inside of the keg and the volume of CO2 gas remaining in the cylinder, so you'll never be caught off guard by an empty gas tank again. This regulator features a single 5/16" barb and a large adjustment knob that is easy to grip and turn for precise pressure placement. For added safety, it also has 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, high-quality performance.
