Devvicoo RV Propane Regulator 2-Tank Auto Changeover Kit — 2-Stage with Braided Stainless Hoses & Glow Indicator

The Devvicoo RV Propane Regulator 2-Tank Hoses kit is a two-stage automatic changeover regulator with dual hoses and safety features that keeps your RV’s propane supply steady and safe.

Designed for RVs, trailers and campers that use two 5–40 lb propane cylinders, this kit combines a two-stage regulator with automatic switching, glow-in-the-dark indicators and braided stainless hoses to deliver a reliable, user-friendly fuel connection. The regulator handles high output demands with separate master and reserve flow capacities, while the included fittings and tools make installation quick for most on-road and off-grid setups.

How does the automatic changeover work and when does it switch tanks?

The regulator continuously monitors cylinder pressure and automatically switches from the primary to the reserve cylinder when the primary runs low. An integrated color indicator shows which tank is active and alerts you when the reserve needs refilling, so you can avoid unexpected outages.

• Automatic transition when primary tank pressure drops.
• Color-coded indicator for quick visual tank status.
• No manual valve flipping required during routine use.
• Excess-flow protection and automatic shut-off to reduce risk.

What are the compatibility and flow specifications?

This regulator kit fits standard RV dual-cylinder setups with 1/4" SAE inverted flare inlets and a 3/8" NPT female outlet, covering most trailers and motorhomes. It supports high-demand appliances thanks to a master cylinder rated at 210,000 BTU/hour and a reserve at 130,000 BTU/hour.

• Fits dual 5–40 lb propane tanks commonly used on RVs and campers.
• 1/4" SAE inverted flare inlet and 3/8" NPT female outlet for broad compatibility.
• Master flow: 210,000 BTU/hr; Reserve flow: 130,000 BTU/hr.

What safety and durability features are included?

The regulator is built with solid brass fittings and a durable chassis to withstand outdoor use, plus braided stainless hoses for abrasion and heat resistance. Built-in leak awareness, glow-in-the-dark gauges and automatic shut-off functions help reduce hazards during operation and maintenance.

• Robust brass construction for corrosion resistance and long life.
• Glow-in-the-dark tank gauge to spot issues in low light without shaking tanks.
• Excess-flow protection and an automatic shut-off valve for added safety.
• Stainless braided hoses resist kinks and wear from travel vibration.

How easy is it to install and what’s included in the kit?

The package is designed for straightforward installation by RV owners or technicians: two 18-inch stainless braided hoses with QCC1 fittings, sealing tape and a wrench are included so you can hook up grills, heaters and other appliances quickly. Clear fittings and standard threads minimize the need for specialty adapters.
