It supports dual propane tanks with automatic switching to ensure uninterrupted fuel supply, rated for 345,200 BTUs. Included are two 12-inch pigtail hoses for easy installation, and a color indicator signals when a tank is empty. Factory-set at 11WC, it guarantees consistent gas pressure under varying conditions. ## Description The Auto-Changeover LP Regulator allows you to hook up 2 Propane tanks and the regulator automatically switches over to the second tank once the first one runs out (and vice versa). The indicator changes color to let you know when a tank has been depleted and needs to be refilled. The inlet is a 1/4" SAE inverted flare and the outlet is a 3/8" NPT female. Also included are 2 of the 12" pigtails to connect the regulator to the propane tank or propane supply. Review: Excelente - This propane gas regulator works very well and feels sturdy and well made. Installation was straightforward, the connections fit securely, and it provides a consistent gas flow. It was a great replacement and has worked reliably.
