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.
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.
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.
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.
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.
Who is this for: The Devvicoo 2-Stage Auto Changeover Regulator is for RV owners, camper van builders and trailer operators who rely on continuous propane for cooking, heating and refrigeration. It's well-suited to people who want a durable, easy-to-monitor dual-tank solution with robust safety features and industry-standard fittings—whether you install it yourself or have a technician do the job.
