Flame King KT12ACR-2 2-Stage Auto Changeover
The Flame King KT12ACR-2 is a two-stage, auto-changeover regulator with two 12-inch pigtails. It supports dual-RV tank setups, automatically switching from the primary to the reserve tank when the primary is depleted.

Best for RVs or vans with dual propane cylinders and a need to continue supply during refills. A potential limitation is the need to manage two supply lines and ensure correct pigtail connections during installation.

Buying Guide: Key Considerations For Dual-Tank RV Propane Regulators
- Changeover Method: Choose automatic changeover to maintain uninterrupted gas flow when one tank is empty. This reduces manual tank switching during travel and camping.
- BTU Capacity: Ensure the regulator’s primary and reserve BTU ratings meet your appliances’ demands. Higher BTU ratings support grills, heaters, and appliances at higher usage.
- Inlets and Outlets: Common configurations use ¼” SAE inverted flare inlets and 3/8″ NPT outlet. Confirm compatibility with your hoses and gas appliances.
- Hose Length And Durability: Long hoses offer routing flexibility but must maintain safety margins. Stainless braided hoses resist wear and outdoor elements.
- Indicators And Gauges: Visual cues for tank status help prevent unexpected gas loss. Gauges are helpful but rely on clear visibility and proper mounting.
- Certification: CSA or UL listings indicate adherence to safety standards. This matters for long-term reliability and insurance considerations.
- Installation Considerations: Some kits include mounting brackets and hardware for quick setup. Check for compatibility with your RV chassis and storage area.
- Safety Practices: Always perform leak checks after installation, and follow manufacturer guidelines for gaskets, tape, and connectors.
