Propane is the lifeblood of most RVs, powering everything from your refrigerator and stove to your water heater and furnace. After decades of working with RV propane systems, I can tell you that while propane is incredibly safe when handled properly, it demands respect and the right equipment.
I’ve seen too many RVers struggle with inadequate propane accessories—leaky connections, unreliable regulators, and systems that leave them guessing about tank levels. The right propane accessories don’t just make your RV more convenient; they make it safer and more reliable.
The challenge with RV propane systems is that they’re often an afterthought until something goes wrong. Factory-installed components are typically adequate but rarely optimal, and many RVers don’t realize how much better their propane system could perform with a few strategic upgrades. From regulators that provide more consistent pressure to gauges that actually tell you how much propane you have left, the right accessories can transform your propane system from a source of anxiety into a reliable, worry-free component of your RV.
Today, I’m sharing my comprehensive guide to the best RV propane accessories available. These are products I’ve personally installed, tested, and relied on throughout my career. Whether you’re concerned about safety, convenience, or simply want to get the most out of your propane system, there’s an accessory here that will improve your RV experience.
Best for: Connecting two appliances to a single propane cylinder with convenient handwheel valves.
When you need to run multiple propane appliances from a single cylinder, the Camco Propane Y Adapter With Handwheel is an essential accessory. This adapter allows you to connect two separate propane devices to one tank, each with its own shutoff valve for independent control. I recommend this adapter to every RVer who uses portable propane appliances like grills, camp stoves, or heaters alongside their RV’s main propane system.
The Camco Y adapter features solid brass construction that ensures durability and leak-free performance. The handwheel valves on each outlet make it easy to control gas flow to each appliance independently, allowing you to shut off one device while keeping the other running. This is particularly useful when you’re using a portable grill and want to shut it off without affecting your RV’s propane supply, or when you’re running multiple camp appliances and need individual control.
Installation couldn’t be simpler. The Y adapter screws directly onto your propane cylinder’s POL or QCC valve, and then your appliances connect to the two outlets. The brass construction provides excellent thread engagement and sealing, and the handwheels are large enough to operate easily even with gloves on. The adapter is compact enough to store easily when not in use, yet robust enough to handle years of regular use.
What I particularly appreciate about this adapter is how it expands your propane system’s versatility without adding complexity. Whether you’re tailgating, camping off-grid, or simply want to run your outdoor kitchen alongside your RV’s propane system, the Camco Y adapter provides a safe, reliable solution. It’s one of those accessories that you’ll use constantly once you have it, wondering how you ever managed without it.

Best for: Adapting between different propane connection types with integrated regulation.
Propane connections come in various types, and sometimes you need to adapt between them. The Marshall Excelsior Propane Tank Adapter With Regulator is a professional-grade adapter that not only converts between connection types but also includes an integrated regulator for consistent pressure. I keep several of these adapters in my toolkit because they solve so many common propane connection challenges.
The Marshall Excelsior adapter is constructed from high-quality brass and steel components designed for years of reliable service. The integrated regulator ensures consistent propane pressure regardless of tank level or ambient temperature, which is critical for proper appliance operation.

Best for: Replacing worn fill valves and ensuring reliable tank filling.
The fill valve on your propane tank is a critical component that’s often overlooked until it starts causing problems. The Manchester Tank Propane Tank Fill Valve is a high-quality replacement valve that ensures reliable, leak-free filling of your propane tanks. I’ve replaced countless worn fill valves over the years, and Manchester Tank valves are consistently reliable and well-made.
The Manchester fill valve features a 1-3/4" Acme thread that’s standard on most RV propane tanks. The valve is constructed from brass with precision-machined threads and a high-quality internal mechanism that ensures proper sealing and reliable operation. The valve includes an internal check valve that prevents propane from escaping when the fill hose is disconnected, and an overfill prevention device (OPD) that stops filling when the tank reaches 80% capacity.
Installation of a fill valve requires some technical knowledge and should typically be done by a qualified propane technician, as it involves evacuating the tank and working with threaded connections that must be perfectly sealed. However, once installed, the Manchester valve provides years of reliable service. The valve operates smoothly, seals completely, and stands up to the repeated connections and disconnections that occur during tank filling.
What I appreciate about Manchester Tank products is their commitment to quality and safety. These valves are manufactured to strict standards and include all the safety features required by modern propane codes. For RVers whose propane tanks have worn or damaged fill valves, replacing them with Manchester valves ensures continued safe, reliable operation.

Best for: Quick, secure propane line connections and disconnections.
Quick disconnect fittings have revolutionized RV propane systems, making it fast and easy to connect and disconnect propane appliances without tools. The MB Sturgis Propane Line Valve Female Quick Disconnect is a professional-grade quick disconnect that provides secure, leak-free connections with a simple push-and-twist motion. I install these fittings on portable propane systems and RV quick-connect ports, and they make propane connections dramatically easier and safer.
The MB Sturgis quick disconnect features solid brass construction with precision-machined components that ensure perfect alignment and sealing. The female quick disconnect connects to a matching male fitting with a simple push and quarter-turn, creating a secure connection that won’t come apart accidentally. The built-in valve automatically shuts off gas flow when the fitting is disconnected, preventing propane from escaping.
What makes this quick disconnect particularly valuable is how it simplifies propane connections. Instead of wrestling with threaded fittings and worrying about proper tightening, you simply push the fittings together and give them a twist. The connection is secure, leak-free, and can be made or broken in seconds. This is especially useful for portable propane appliances like grills that you connect and disconnect frequently.
The MB Sturgis fitting is also excellent for RV exterior quick-connect ports that allow you to run propane to outdoor appliances. The automatic shutoff valve means you can disconnect appliances without shutting off your main propane supply, and the robust construction ensures years of reliable service. For RVers who value convenience and safety in their propane connections, quick disconnect fittings are an essential upgrade.

Best for: Safely securing portable propane cylinders during travel and use.
Portable propane cylinders need to be secured properly during travel to prevent them from tipping, rolling, or becoming projectiles in an accident. The Camco Stabilizing Base For 20-30 Lb Propane Cylinders provides a safe, stable platform for your propane tanks that keeps them secure during travel and stable during use. I recommend these bases to every RVer who carries portable propane cylinders.
The Camco stabilizing base is constructed from heavy-duty plastic that’s designed to withstand years of outdoor use without cracking, fading, or deteriorating. The base features a circular design that cradles your propane cylinder, preventing it from tipping over on uneven ground. The base also elevates the cylinder slightly, keeping it off wet or dirty surfaces and improving stability.
What makes this base particularly useful is how it simplifies propane cylinder storage and transport. Instead of trying to wedge your cylinder into a storage compartment or worry about it rolling around during travel, you simply place it in the Camco base and secure it with a strap or bungee cord. The base keeps the cylinder upright and stable, preventing damage to the valve and ensuring safe transport.
The base is also excellent for use at your campsite. It provides a stable platform for your cylinder when using portable appliances, preventing the cylinder from tipping if someone bumps into it or if you’re on uneven ground. The base is lightweight and stackable, making it easy to store multiple bases when not in use. For the modest investment, it’s excellent insurance for your propane cylinders and your safety.

Best for: Monitoring propane levels and detecting dangerous leaks.
One of the most frustrating aspects of RV propane systems is not knowing how much propane you have left. The Camco Propane Gauge/Leak Detector solves this problem while also providing critical leak detection capability. This dual-function device is one of the most useful propane accessories you can add to your RV, and I recommend it to virtually every RVer I meet.
The Camco gauge/leak detector installs inline between your propane cylinder and your regulator or appliance. The gauge provides a visual indication of the pressure in your propane system, which correlates to how full your tank is. While not as precise as weighing your tank, the gauge gives you a good indication of whether you’re running low and need to refill soon. The leak detection function is equally valuable—the gauge includes a small viewing window that changes color if it detects propane in the air, alerting you to a potential leak.
Installation is straightforward. The gauge screws onto your propane cylinder’s outlet, and then your regulator or hose connects to the gauge’s outlet. The gauge is compact and doesn’t interfere with normal operation of your propane system. The clear display is easy to read at a glance, and the leak detector window is positioned where it’s visible during normal use.
What I particularly value about this device is the peace of mind it provides. You’ll never again run out of propane unexpectedly in the middle of cooking dinner, and you’ll have an early warning system for leaks that could be dangerous. The dual functionality makes it an excellent value, combining two essential functions in one compact, affordable device.

Best for: Comprehensive safety monitoring of propane and carbon monoxide.
Safety should always be the top priority when dealing with propane, and a quality detector is essential for protecting yourself and your family. The RV Safe Propane Gas & CO Detector/Alarm provides dual protection, detecting both propane leaks and carbon monoxide buildup. I consider this type of detector mandatory equipment for any RV, and I’ve installed hundreds of them over the years.
The RV Safe detector uses advanced sensors to detect even small amounts of propane or carbon monoxide in your RV’s air. The detector sounds a loud alarm if it detects dangerous levels of either gas, giving you time to ventilate your RV and address the problem before it becomes life-threatening. The unit features separate indicators for propane and CO, so you know exactly what hazard you’re dealing with.
Installation requires mounting the detector in an appropriate location and connecting it to your RV’s 12V electrical system. Propane is heavier than air and sinks, so the detector should be mounted low, near the floor. The RV Safe unit includes complete installation instructions and mounting hardware. Once installed, the detector operates continuously whenever your RV has power, providing constant protection.
What makes this detector particularly valuable is its dual-function capability. Propane leaks and carbon monoxide buildup are both serious hazards in RVs, and having a single device that monitors for both provides comprehensive protection. The detector includes a test button for verifying proper operation, and the sensors are designed to last for years before needing replacement. For the modest investment, it’s essential safety equipment that could save your life.

Best for: Simple, reliable visual monitoring of propane tank levels.
Sometimes the simplest solutions are the best, and the AP Products Tank Check Propane Level Indicators provide a brilliantly simple way to monitor your propane levels. These magnetic indicators attach to the outside of your propane tank and change color to show the liquid level inside. I’ve used these indicators for years and find them surprisingly accurate and reliable.
The Tank Check indicators work by detecting the temperature difference between the liquid propane and the gas space above it. Liquid propane is colder than the gas, and the indicator strips change color at the boundary between the two. You simply run warm water over your propane tank (or wait for a sunny day), and the indicators show you exactly where the liquid level is. The set includes two indicators, allowing you to monitor both of your RV’s propane tanks.
Installation couldn’t be easier. The indicators have magnetic backs that stick to the steel propane tank. You position them vertically on the side of your tank, and they’re ready to use. There’s no wiring, no calibration, no maintenance. The indicators are weather-resistant and designed to withstand years of outdoor exposure without fading or losing their magnetic grip.
What I appreciate about these indicators is their simplicity and reliability. They don’t require batteries, they can’t malfunction, and they provide a clear visual indication of your propane level. While they’re not as precise as weighing your tank, they’re more than accurate enough to tell you when you’re getting low and need to plan for a refill. For the modest cost, they’re an excellent addition to any RV propane system.

Best for: Professional-grade leak detection and system testing.
Detecting propane leaks is critical for safety, and while electronic detectors are excellent for continuous monitoring, sometimes you need to test specific connections and fittings. The Valterra Detect-A-Leak Propane Gas Leak Detector Fluid is a professional-grade leak detection solution that makes it easy to identify even tiny leaks in your propane system. I use this fluid every time I work on a propane system, and I recommend that every RVer keep a bottle on hand.
The Detect-A-Leak fluid is a specially formulated solution that creates bubbles when it comes into contact with escaping propane gas. You simply brush or spray the fluid onto your propane connections, fittings, and hoses, and watch for bubbles. If bubbles form, you’ve found a leak. The one-gallon size is perfect for RVers who want to keep a supply on hand for regular system checks.
What makes this leak detector particularly effective is its sensitivity. It can detect even very small leaks that might not be noticeable by smell or sound. The fluid is non-corrosive and safe to use on all propane system components, including brass fittings, steel tanks, and rubber hoses. The Valterra fluid is also environmentally friendly and won’t damage your RV’s exterior if it drips.
I recommend testing your propane system for leaks at least once a season, and always after any work on the system. Apply the leak detector fluid to all connections, fittings, and hoses, and watch carefully for bubbles. If you find a leak, tighten the connection or replace the component before using your propane system. The peace of mind that comes from knowing your system is leak-free is well worth the few minutes it takes to perform this simple test.
