Flame King 2-Stage Auto-Changeover LP Regulator | Dual-Tank, 12" Pigtails, 345,200 BTU

This Flame King regulator lets you run two propane tanks at once, automatically switching from the primary tank to the reserve tank the moment the first one empties out, and back again once it's refilled and reconnected.

An indicator changes color to show when a tank needs a refill, and two 12-inch pigtail hoses are included to connect the regulator to each tank. The double-stage design keeps gas pressure steady even as demand changes.

• Automatic changeover between two propane tanks
• Two 12" pigtail hoses included
• 1/4" SAE inverted flare inlets, 3/8" NPT female outlet
• Rated for 345,200 BTU
• Factory set at 11" water column
• UL listed

A solid pick for RVs, vans, and trailers running dual tanks that don't want to lose propane supply mid-trip.
