Flame King KT12ACR-2: Two-Stage Auto Changeover Regulator
The Flame King KT12ACR-2 is a two-stage automatic changeover regulator designed for RVs, vans, and trailers with dual propane tanks. It allows removal of the empty cylinder for refill without interrupting propane supply. Included are two 12-inch pigtails to connect the regulator to either tank or supply. The unit switches from the primary to the reserve tank when the primary is empty, ensuring uninterrupted operation. It uses 1/4″ SAE inverted flare inlets and a 3/8″ NPT outlet. Rated up to 345,200 BTU, it suits mid- to large-RV configurations.
Key features include UL listing for safety, and a design focused on easy swapovers without manual shutdown. The dual-tank compatibility makes it ideal for long trips where one cylinder may deplete while appliances stay lit. Installation typically involves mounting and connecting the pigtails to your propane system, with careful adherence to gas safety guidelines.
Flame King KT12ACR-2a: Auto Changeover Regulator Kit
The KT12ACR-2a mirrors the KT12ACR-2 design with dual tanks and automatic switching between primary and reserve sources. It comes with two 12-inch pigtails for flexible mounting and connection to your LP system. This regulator remains UL listed, with 1/4″ SAE inverted flare inlets and a 3/8″ NPT female outlet. The 345,200 BTU rating supports a broad range of propane appliances on RVs, making it a robust choice for travelers who rely on consistent gas pressure.
In practice, this model supports simple maintenance; if a tank runs low, you’ll experience an automatic transition and a steady gas flow to grills, heaters, or stoves. Users should verify tank compatibility and ensure proper sealant use on threaded connections during install. The two-tank design helps manage longer trips without frequent tank swaps.
2-Stage Auto Changeover With Dual Propane Hoses and Gauge
This 2-stage regulator package is designed for RVs with two tanks and includes two hoses with built-in gauges. It supports automatic switching from primary to reserve cylinder and uses a color-changing indicator to show when a tank is depleted. The main regulator has a primary capacity of 210,000 BTU/hr and a reserve capacity of 130,000 BTU/hr. All fittings use 1/4″ SAE inverted flare inlets and a 3/8″ NPT outlet. The stainless steel braided hose adds durability and weather resistance for outdoor use.
The kit emphasizes safe, uninterrupted supply by signaling when a refill is needed and by preventing leakage during tank transitions. The rugged brass construction and CSA certification reflect attention to quality and regulatory compliance, making it suitable for frequent RV travelers and full-time campers alike.
RV Propane Regulator Kit With Dual Hoses and Gauge
This kit provides a dual-tank propane regulator setup with hoses featuring a glow-in-the-dark tank gauge to indicate remaining gas. It employs a two-stage regulator with a Master cylinder capacity of 210,000 BTU/hr and a reserve cylinder of 130,000 BTU/hr. The system switches between tanks automatically, helping to maintain pressure while refilling happens. The hoses are stainless steel braided for durability, with 1/4″ male inverted flare fittings and a 3/8″ NPT end on the regulator.
Users should follow the note-based installation steps to avoid leaks: connect the hose to the regulator before attaching to the tank, and ensure proper tightening and leak checks. The assembly is targeted at RV, trailer, and camper gas systems requiring reliable dual-tank operation for continuous cooking and heating.
Buying Guide: Choosing a Propane Tank Automatic Switchover System
- Tank compatibility and capacity: Verify the BTU rating for your appliances and ensure the regulator can handle peak demand without pressure drop.
- Two-stage regulation: Look for true two-stage regulators that maintain steady pressure through switching and reduce fluctuations in gas flow.
- Automatic switchover functionality: Ensure the unit switches seamlessly between primary and reserve tanks and provides a clear indicator when a tank is depleted.
- Connections and fittings: Check inlet and outlet sizes (commonly 1/4″ SAE inverted flare inlets and 3/8″ NPT outlets) and verify compatibility with your hoses and tanks.
- Durability and safety certifications: UL or CSA certifications indicate adherence to safety standards. Brass construction and stainless steel hoses improve longevity in outdoor RV environments.
- Installation considerations: Some kits include pre-mounted brackets or longer hoses for easier mounting in tight spaces. Follow manufacturer steps to prevent leaks and ensure a proper seal.
- Indicators and maintenance: A visual gauge or indicator improves monitoring of tank status. Regular inspection for leaks, corrosion, and wear extends system life.
- Portability and weight: For travelers who move frequently, lighter units with compact hoses ease setup and storage.
- Price versus features: Compare BTU capacity, hose length, gauge availability, and warranty when weighing costs.
- Warranty and support: A solid warranty and accessible customer support help address potential installation questions or component replacements.
