Devvicoo RV Propane Regulator 2-Tank Auto Changeover with Stainless Braided Hoses & Glow Indicators

The Devvicoo RV Propane Regulator 2-Tank Hoses is a 2-stage automatic changeover system that switches between two propane cylinders to keep your RV appliances running without interruption.

Designed for RVs, campers and trailers that use dual 5–40 lb propane tanks, this complete kit combines a two-stage regulator with automatic tank switching, glow-in-the-dark level indicators, and stainless braided hoses so you can install and manage on-board propane safely and reliably. Built with solid brass fittings and excess-flow protection, it balances steady delivery with proactive shutoff features to reduce leak and flow risks while supporting high-BTU appliances.

How does the automatic changeover work and prevent service interruptions?

The regulator monitors the primary tank and switches to the reserve tank the moment pressure on the active tank drops below a safe threshold. A color-coded indicator on each cylinder lets you know which tank is supplying gas and which one needs refilling, so you can swap tanks before appliances are affected.

• Automatic two-tank switch-over when primary supply is depleted
• Color indicator shows active and empty tanks for easy monitoring
• No manual valve flipping required; seamless transition maintains appliance operation

What fittings and flow capacity does this regulator support?

The Devvicoo regulator is built to common RV standards: 1/4" SAE inverted flare inlets for the tanks and a 3/8" NPT female outlet for appliance piping. The master cylinder supports up to 210,000 BTU/hour while the reserve side supports 130,000 BTU/hour, suitable for most onboard heating, cooking and refrigeration loads.

• 1/4" SAE inverted flare tank inlets for universal fit on RV cylinders
• 3/8" NPT female outlet for standard RV gas lines
• 210,000 BTU/hr master capacity and 130,000 BTU/hr reserve capacity

What safety and monitoring features are included?

Safety is addressed through solid brass construction, excess-flow protection, an automatic shut-off valve and glow-in-the-dark tank indicators that help you spot leak conditions and liquid levels without shaking the cylinders. These elements work together to reduce the chance of uncontrolled flow and to make routine checks simpler in low light.

• Solid brass fittings resist corrosion in outdoor environments
• Excess-flow protection and automatic shut-off reduce hazardous flow events
• Glow-in-the-dark indicators help detect leaks and tank levels quickly

What comes in the kit and how easy is installation?

The package includes two 18-inch stainless braided hoses with QCC1 fittings, sealing tape and a wrench, so you have the hardware needed for a straightforward swap-in or new installation. The kit is intended for users familiar with RV propane connections or professional installers, and it’s sized to fit common dual-tank configurations on trailers and motorhomes.

• Two 18" stainless braided hoses with QCC1 fittings for quick hook-up
• Sealing tape and wrench included for a complete installation
• Designed for simple replacement of existing dual-tank regulators
