Seamless Propane Supply for Dual Tank Systems

The Flame King ACR-2 Automatic Changeover Regulator Kit ensures a steady flow of propane to your RV, even when one tank runs out. Designed for dual-cylinder systems, this smart regulator automatically switches from your primary tank to the reserve without interrupting your supply - so your heat, appliances, and comfort are never compromised.

Smart, Automatic Changeover System

No more manual tank swaps. When the primary tank empties, the built-in changeover system seamlessly pulls propane from the reserve tank. Just rotate the lever to reset the indicator, and you're ready to refill the empty tank without losing pressure or flame.

Clear, Easy-to-Read Indicator

The front-facing indicator shows clear when the active tank has propane and switches to red when empty - giving you a visual cue to refill. It's a quick and easy way to monitor your propane levels.

Dual 12-Inch Pigtail Hoses Included

This kit includes two 12-inch pigtail hoses to connect each tank to the regulator, providing flexible reach and a secure, leak-free fit.

Consistent, Stable Pressure

A double-stage regulator design maintains a constant 11" WC (water column) pressure - the optimal setting for most RV appliances - regardless of changing propane demand or outside conditions.

Built for Performance

With a high flow capacity of up to 345,200 BTU, this UL-listed regulator supports everything from RV heating and cooking to water heaters and outdoor grills. Inlets feature 1/4" SAE inverted flare fittings; the outlet is 3/8" NPT female pipe thread.

Pairs Perfectly with Flame King's 48" Thermoplastic Hose

They recommend this to me for the tanks. and they will not work on the propane tanks. I have to buy adapters for them. Which is an extra cost that I could have diverted.

Plastic nut cracked

My photo looks like a few others in the reviews, the plastic nut cracked. Only made it for 8 months. I also had some difficulty swapping tanks using the switch but it's the first time I used that feature so I may have done something wrong, though it seems like a simple thing...
