If you enjoy hot showers, a working fridge, being able to cook, and so much more, you can thank your RV propane regulator. It’s easy to forget this little equipment piece, but it plays a crucial role in how your RV uses propane to power vital systems. Read on to learn how!

What Is an RV Propane Regulator? 

To understand how this essential component works, you must know a little about how RV propane systems work. 

Your propane will be stored at extremely high pressure while in the tank–much higher than your appliances could handle. An RV propane regulator takes that high-pressure propane and reduces it to a pressure usable for your RV systems.

Are Propane Regulators All the Same? 

No. All propane regulators may perform the same primary function, but the specific types can vary based on the propane system type. 

First-stage regulators are what you’ll find on gas grills, camp stoves, and propane firepits. You can sometimes use them along with a second-stage regulator, which further reduces propane pressure before it reaches the appliance. 

Most commonly, RVs will have integral twin stage or dual regulators, which help share the propane between multiple appliances. Some high quality regulators even have an automatic changeover feature when one tank is empty.

What to Look for When Buying an RV Propane Regulator

Like any piece of technical equipment for your RV, buying a new regulator can feel a little overwhelming. Here are a few key things to help focus your shopping and buy a high quality regulator.


Scientists measure capacity in BTUs (British thermal units), which initially represented the amount of heat required to increase one pound of water temperature by 1 degree Fahrenheit. 

It now has a more technical definition, but the principle is the same. The more BTU capacity your regulator has, the more power and capacity your RV propane system has. Generally, most regulators will have enough capacity to power most RVs, although some rigs require special high-capacity units.


While most models are very affordable (starting around $30), consider your budget and your propane needs when shopping. 

Additionally, consider the savings from increased efficiency. If you have a more efficient propane regulator, it might reduce your power usage and save you more money in some cases. It might be worth purchasing a more expensive unit initially to reap cost savings long term. 


You want to know how the product is working in real life with real RVers. Read various reviews to learn about the ease of installation and use, any common or recurring problems, or general advice from current owners.
