JR Products Automatic Changeover Regulator | Dual-Cylinder LP Gas

Running two propane cylinders means one can serve as backup, but only if the switch-over happens automatically when the first one runs dry. This regulator handles that transition on its own, so you're not left without gas mid-use, and its color-changing dome tells you when the empty cylinder needs to be swapped or refilled.

• Automatically redirects gas flow from an empty cylinder to the reserve tank
• Green-to-red indicator dome shows when a cylinder needs filling
• 1/4" inverted flare inlet connections with a 3/8" FPT outlet
• Die-cast zinc body for durability
• UL approved

A practical setup for anyone running dual cylinders who wants to avoid running out of gas without warning.
