A successful camping trip is dependent upon several factors. Your RV should be comfortable, enjoyable, relaxing, and welcoming.  

But what happens when there is no hot water for showers? Or dinner turns into sandwiches because the 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 a lot of 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.

All About 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. 

There are unique components that are compatible with propane systems. These components are made from high-quality materials that can handle propane. These components also 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

Propane system overview

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:

1.    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 liquid propane gas (or LPG) to your RV. Propane tanks must be secured to the frame of your RV for safety.

2.     RV Propane Pigtail Hose:

A propane tank is only useful 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.

3.     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.

4.     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.

5.     Propane Safety Features:

Manufacturers integrate safety features into the propane system. At the propane tank, there is an overfill protection device. This device makes it impossible to overfill the tank. 



Important things to note: In case of fire, turn propane tank off. In case of broken gas line, turn the propane tank off.

Thermocouples are a safety device at the pilot light of your propane appliances. A thermocouple 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 a handy tool 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 that connects your propane tanks to the regulator. Pigtails must be able to handle the high pressure LPG coming from the tank. There are specific hoses for the pigtails and the main supply line. 

Types of RV Propane Hose Fittings:

Different propane fittings RV

There are different fittings for different propane hoses. It is essential to ensure you buy your RV hoses with the appropriate size and fittings. 

Type 1 (ACME) fittings:

These are on the propane tanks. The propane tank will have a male Type 1, and the Pigtail will have a female Type 1. These are typically on travel trailers with propane tanks on the outside. The ACME nut is the pigtail handle that screws into the propane tank.

POL fittings:

These are on the propane tanks. These fittings are typically on onboard propane tanks. 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 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.

Frequently Asked Questions

Does Propane Require a Special Hose?

Propane hoses are the only hoses that are 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 have on the insides of hoses. When a propane hose ages and is exposed to the elements, it can dry out and start to crack. Inspecting your hoses is necessary to ensure there is not a leak outside.

Are All RV Propane Hoses the Same?

All RV propane hoses are not 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. If your propane hose is in the harsh elements, like direct sunlight and frequent freezing, it may degrade faster than five years. It is 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. Propane hoses have a manufacturing date. You should periodically inspect propane pigtails for cracks and leaks. 

If you smell propane near your tanks, there may be a leak. Inspect the pigtails for leaks by spraying soapy water on the connections and the pigtails. 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.

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 included some budget picks for some cost-effective options as well. 

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.

–    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 threads of the tank fitting. Make sure the connection is secure; do not over-tighten.

–    Turn the propane tank back on.

–    Use soapy water to spray connections to check for any leaks.
