Comparing FlameKing Models

Our category features two standout options tailored for RVs, vans, and trailers. Both deliver 2-stage auto changeover technology, but they cater to different installation preferences.

ACR-2a: Without Pigtails

This versatile model is perfect for users who prefer custom hose lengths or already have pigtails in place. Its compact design simplifies integration into tight RV compartments, ensuring reliable performance without unnecessary bulk. Ideal for DIY enthusiasts upgrading Grills & Outdoor Cooking setups or van life conversions.

KT12ACR-2: With Two 12-Inch Pigtails

For plug-and-play convenience, this version includes two durable 12-inch pigtails for direct tank attachment. It minimizes setup time and reduces potential leak points, making it a favorite for frequent travelers. The added pigtails offer flexibility for dual-tank systems, outperforming basic regulators in ease of use.

Choose the ACR-2a if you value customization; opt for the KT12ACR-2 for out-of-the-box readiness. Both models maintain consistent output pressure, even under varying temperatures, and integrate seamlessly with propane appliances.

Common Use Cases

FlameKing regulators shine in mobile and outdoor scenarios. RVers appreciate the auto-changeover for long trips, eliminating manual swaps mid-cookout. Grill masters in the Patio, Lawn & Garden category use them to stabilize pressure for even cooking. They're also popular for off-grid vans and trailers, where reliable fuel delivery is non-negotiable. Compared to competitors like DOZYANT Gas Regulators, FlameKing offers superior flow rates for high-demand burners.
