Flame King KT12ACR-2 2-Stage Regulator With Two 12 Inch Pigtails
This UL-listed regulator is designed for RVs with dual propane tanks. It automatically switches from the primary tank to the reserve tank when the primary is empty, ensuring continuous propane supply. It includes two 12-inch pigtails to connect to tanks or a supply line. Best for: travelers who want a straightforward, compact solution with easy tank interchangeability. Caution: limited to 12-inch hose reach; plan longer runs if your setup requires more space.
Flame King ACR-2a 2-Stage Auto Changeover Regulator
This regulator is suited for RVs and trailers with two tanks, automatically moving from primary to reserve when needed. It’s UL listed with 1/4″ SAE inverted flare inlets and a 3/8″ NPT outlet. Best for: buyers who want a reliable, budget-friendly dual-changeover setup without included hoses. Caution: does not come with pigtails, so additional hoses may be required for full installation.
Flame King KT18ACR-2 2-Stage Auto Changeover Regulator With 18-Inch Pigtails
This unit extends the standard dual-regulator design with two 18-inch pigtails, making it ideal for setups where tanks are farther apart or under a larger trailer. It features UL-listed regulation and maintains a 345,200 BTU rating. Best for: larger RVs or trailers with longer hose paths. Caution: longer hoses can introduce slight pressure loss if not paired with appropriate diameters.
Flame King KT15ACR-2 2-Stage Auto Changeover with 15-Inch Pigtails
With 15-inch pigtails, this option balances compactness and reach. It supports dual-tank operation and switches seamlessly between tanks. Best for: standard-size RV configurations where space is adequate but shorter hose lengths are preferred. Caution: not optimal for very tight spaces where longer hoses are unnecessary.

This kit contains a 2-stage regulator plus two 18-inch hoses with gauge, designed for dual-tank RV setups. It indicates when a tank is empty and switches to the reserve tank automatically.

Buying Guide
Key considerations for selecting a travel trailer dual propane regulator:
- Tank configuration: Ensure the regulator supports dual tanks and auto-changeover to maintain continuous gas supply.
- Hose length and fittings: Match pigtail lengths (12″, 15″, 18″) to your trailer layout; verify inlet/outlet connections (1/4″ SAE inverted flare, 3/8″ NPT) fit your hoses and tanks.
- BTU rating: A higher BTU rating handles larger propane demands; confirm your system’s BTU requirements align with the regulator’s output (e.g., 345,200 BTU is common for these units).
- Convenience: Some kits include hoses and gauges; others require purchasing fittings separately. Decide if you prefer an all-in-one bundle.
- Durability and certification: Brass construction and UL/cSA listings improve safety and longevity; look for CSA/UL-listed regulators.
- Installation: Some models are designed for easy swap without interrupting supply; others may require professional help to ensure proper sealing and leak testing.
Practical tips for installation and use
- Follow manufacturer instructions for initial hose connections without sealing tape, then seal per guidelines during final assembly.
- Test for leaks after installation using soapy water. Do not use a flame for testing.
- Keep regulator and hoses away from heat sources and road debris; secure hoses to prevent movement while driving.
FAQ
- Do I need two regulators for dual propane tanks? Not always; a 2-stage auto-changeover regulator is designed to manage both tanks with automatic switching, reducing the risk of interruptions.
- What is the typical hose length I should choose? Choose based on your trailer layout; common lengths are 12″, 15″, and 18″. Longer hoses provide flexibility but may add small pressure considerations.
- Are these regulators UL listed? Many models shown are UL-listed or CSA-certified, which supports safety and compliance for RV use.
- Can I install these myself? Installation ranges from simple to moderate; follow the included instructions and consult a professional if you’re unsure about fittings or sealing requirements.
- What does “changeover” mean in this context? It means the regulator automatically switches gas supply from the primary tank to the reserve tank when the primary runs low or is empty.
- Is it okay to mix different brands of hoses with these regulators? It’s best to use hoses and fittings that match the regulator’s specified inlet/outlet sizes and compatibility to prevent leaks or pressure issues.
