A successful camping trip depends on several factors. Your RV should be comfortable, enjoyable, relaxing, and welcoming.
But what happens when there is no hot water for showers? Or does dinner turn into sandwiches because the RV gas stove won’t work? Take the time to ensure your gas keeps flowing before you hit the road.
I’ve been a career firefighter for over a decade. I’ve spent much time responding to gas leaks and educating people on safety. I know firsthand how propane can make people anxious.
I have taken the time to break down the propane system so it is more manageable. I’ve also compiled a list of products I trust enough to use in my RV and recommend to my loved ones.
Your RV Propane System
When it comes to RVing, the safety and functionality of your propane system are critical. Propane leaks can be dangerous. And issues in your system can leave you without propane-fueled appliances.
Unique components are compatible with propane systems. They are made from high-quality materials that can handle propane and have additional safety features to ensure they function appropriately.
Let’s break down the RV Propane System into the basics.
Main Components of an RV Propane System
The RV propane system consists of several vital components. Each of these components plays a crucial role in the function and safety of the system. The main components are:
Propane Tanks
The entire propane system relies on a propane cylinder to function. RVs do not connect to natural gas lines like houses do. Propane tanks are essential for providing your RV with liquid propane gas (or LPG). For safety, propane tanks must be secured to the frame of your RV.
RV Propane Pigtail Hose
A propane tank is only helpful if you can connect it to your propane system. This is where pigtails come into play. Pigtails are flexible RV propane connection hoses that connect the propane tank to the propane regulator. These hoses often feature a 1/4 inverted male flare for a secure connection to the propane regulator, ensuring a tight and leak-free link between the tank and your RV’s propane system. For optimal safety and efficiency, selecting new hoses with the correct 4 inverted male flare specification is important. RV owners might consider replacing their original hoses with new, higher-quality ones to prevent leaks and ensure a secure connection. This upgrade to new hoses, which are heavier and shorter with a larger outer diameter and the right fittings, can significantly enhance the reliability and safety of your RV’s propane system.
Propane Regulator
Propane tanks are filled with liquid propane gas. The liquid gas is under pressure inside the tank. Propane tanks have an internal pressure of 120-200 PSI. For the system to work safely and efficiently, it must reduce the pressure. The regulator controls the amount of propane entering your system.
A propane regulator is necessary to reduce the pressure of the propane as it leaves the tank. The regulator reduces the pressure and controls the flow of propane. Your RV appliances require proper propane flow and pressure. Always protect your RV by selecting high-quality regulators.
Main Supply Hose
Now that your regulator has successfully reduced the propane pressure, it is ready for use in your RV. A main supply hose carries propane from the regulator to the various propane appliances inside your RV.
Propane Safety Features
Manufacturers integrate safety features into the propane system. For example, the propane tank has an overfill protection device that prevents overfilling.
Important to note: Turn the propane tank off in case of fire or a broken gas line.
Thermocouples are safety devices installed in the pilot light of your propane appliances. They can detect if the pilot is on. If the thermocouple does not sense heat from the pilot light, it shuts off the propane flow to the appliance. This safety measure keeps propane from flowing into the RV when the pilot isn’t working.
One of the most essential safety features for propane use in an RV is a Carbon Monoxide and Propane Leak Detector. This detector is handy for alerting an RVer of unsafe levels within the living space.
The Propane Pigtail and Its Role
The RV propane pigtail is the flexible hose connecting your propane tanks to the regulator. Pigtails must be able to handle the high-pressure LPG coming from the tank. Specific hoses are for the pigtails and the main supply line.
Types of RV Propane Hose Fittings
OL Fittings
These fittings are on the propane tanks, which are typically onboard. The tank will have a male POL, and the connector will have a female POL.
Inverted Flare Fittings
These are on the regulator and the end of the Pigtail that hooks into the regulator.
NPT Fittings
These are also on some regulators and the ends of some pigtails.
Flare Fittings
Found on the end of the main supply hose that attaches to the main line.
Quick-Disconnect Fittings
These quick-connect fittings are on the grill, outside kitchen, and tee connections.
1″ -20 Fittings
These fittings connect smaller portable propane cylinders to small appliances. These propane cylinders are throw-away.

The following products are those that I either currently use or consider as a second option. I believe in selecting the highest-quality products for a propane system. I have also included some budget picks for cost-effective options.
Best RV Propane Pigtails
Always inspect your existing setup before buying replacement hoses. Many RVs come with owner manuals that include parts numbers so that you can find a compatible replacement. You can also look up the information of the hose you are replacing to select the identical size.

How To Install New RV Pigtails
- Shut the propane tanks off.
- Remove the old Pigtails by unscrewing the fitting from the tank.
- Optional-Use yellow Teflon tape (PFTE) or pipe dope around the threads of the tank fitting to avoid leaks. (yellow tape is specifically for propane fittings)
- Attach a new pigtail to the tank fitting’s threads. Make sure the connection is secure; do not overtighten.
- Turn the propane tank back on.
- Use soapy water to spray connections to check for any leaks.
Frequently Asked Questions
Does Propane Require a Special Hose?
Propane hoses are the only hoses for propane. The hoses and fittings work together to handle propane safely. Fittings from other types of hoses will not work with propane systems.
Propane hoses are resistant to the corrosion that gas can cause on their insides. However, when a propane hose ages and is exposed to the elements, it can dry out and start to crack. Therefore, it is necessary to inspect your hoses to ensure there is no leakage or leak outside.
Are All RV Propane Hoses the Same?
Not all RV propane hoses are the same. High-quality hoses have materials like stainless steel and synthetic rubber layers. Spending money on high-quality hoses will ensure that your hoses last longer.
How Long Do RV Propane Hoses Last?
Propane hoses usually last around five years. However, if your propane hose is exposed to harsh elements, like direct sunlight and frequent freezing, it may degrade faster than five years. Therefore, it is a good practice to inspect your hoses for cracking.
When to Replace a Propane Pigtail Hose
Inspect propane hoses regularly and replace them every five years. They have a manufacturing date. You should also periodically inspect propane pigtails for cracks and leaks.
If you smell propane near your tanks, there may be a leak. Spray soapy water on the connections and the pigtails to inspect for leaks. The soapy water will bubble at the source of the leak. Once you have located the leak, turn off the tank and replace the leaky hose.
