2-Stage Auto Changeover Propane Gas RV Regulator Kit with Two 12 in. Pigtails

The Auto-Changeover LP Regulator allows you to hook up 2 Propane tanks. 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 in. SAE inverted flare and the outlet is a 3/8 in. NPT female. Also included are 2 of the 12 in. pigtails to connect the regulator to the propane tank or propane supply.
