    What to Look for When Buying An RV Propane Regulator

    Types of RV Propane Regulators

    When it comes to propane regulators, there are three major varieties to choose from. So let us begin by identifying each of these classes and give a few advantages and disadvantages for each.

    Single-Stage RV Propane Regulator

    The good news is that single-stage regulators can almost entirely be avoided because they are incompatible with most RVs, travel trailers, and fifth wheels. However, you should be aware of them because you will want to avoid these regulations during your search.

    Single-stage regulators are more commonly used in BBQ grills or tiny camping stoves in the camping world. Attempting to use one in an RV will result in erratic and unpredictable gas flow, which can be detrimental to your health and the health of your RV.

    Two-Stage Propane Regulator For RV

    Two-stage regulators are far more prevalent in RVs, however they are best suited to larger RVs. Their two stages contribute to more uniform gas flow while also allowing for gas flow at higher pressures. This enables them to properly deliver propane to RV water heaters, furnaces, stoves, ovens, and other appliances. However, they are more frequent on larger rigs that have a single onboard propane tank with a horizontal nozzle.

    Automatic Dual Tank RV Propane Regulators

    Automatic twin tank regulators are more typically found in travel trailers and fifth wheels that have dual propane tanks mounted vertically someplace on the rig.

    These are normally smaller tanks, and the regulators are programmed to move from one tank to the other when the first is empty. If you have an RV, travel trailer, or fifth wheel with multiple tanks, you will require an automatic dual tank regulator. This also allows you to remove and refill one propane tank while the regulator continues to supply steady gas flow to your RV’s key appliances.


    Given the significant position this product will play inside your RV’s propane system, you must ensure it is of excellent quality; hence, inspecting the materials it was constructed from becomes an important part of this entire process. These regulators, as you can see, aren’t going to endure forever. Even the greatest models have a 15-year lifespan, so selecting one that comes close to that figure becomes essential. As a result, you must do a thorough study of the product’s materials before deciding on the best model.

    In most circumstances, this means determining whether a regulator’s aluminum, brass, raw zinc, or stainless steel construction is long-lasting. And the easiest method to determine this is to read the customer reviews.

    After all, nothing irritates a customer more than a product that fails or malfunctions. Trust me when I say that if any of the products you’re contemplating has a durability issue, there will be a slew of disgruntled, spiteful people in the customer review section. Another thing to keep an eye out for is the phrase “heavy-duty construction.” This phrasing indicates that the maker was concerned about how effectively their product would withstand environmental conditions that could cause difficulties, such as rust or corrosion.

    Ease of Installation

    Unlike many RV-related equipment, a propane regulator usually does not require a lengthy installation procedure. In reality, you can typically accomplish it on your own without the assistance of a professional.

    However, there may be some minor difficulties with specific models. If you desire an automatic dual propane regulator, for example, there will be variants that do not include mounting hardware. Its absence may make the installation process more difficult for the consumer. And this isn’t the circumstance that could lead to installation issues. With this in mind, it is evident that you will need to rely on those pesky customer reviews once more. The consumer experiences in these reviews will give you a good idea of how difficult the installation process is.

    We should also point out that it’s a good idea to make sure the propane regulator you buy comes with all of the tools you’ll need to install it. Purchasing parts or tools separately will only lead to more research, which you will not want on your pleasant RV trip.

    Capacity (BTU Rating)

    The capacity of a propane regulator is determined by its BTU rating. BTU is an abbreviation for British Thermal Units, which is the amount of energy required to raise the temperature of one pound of water by one degree Fahrenheit. While this may seem perplexing at first because we’re talking about gas here (rather than water), you should know that BTUs are the common unit used to define the capacity of many of your gas-powered RV appliances inlet.

    In the case of propane regulators, a greater BTU rating usually equates to a higher capacity. But what BTU rating is truly required to make a propane regulator capable of producing adequate gas flow to your RV? To begin, we recommend looking for a regulator that has a minimum rating of 100,000 BTUs per hour. However, several of our picks for the best RV propane regulator have a lot higher rating than that. If you have a larger RV with many propane-powered appliances, you will need a regulator with a greater BTU rating.

    This means that smaller RVs or travel trailers with fewer propane-powered appliances may not necessitate a regulator with a high BTU rating. Having said that, the easiest approach to guarantee that the BTU rating on your new regulator matches the specifications of your RV is to consult the owner’s manual for your vehicle.

    This document should provide you with the necessary information regarding the minimum and maximum BTU values recommended for your rig’s propane system. If you can’t find anything there, don’t be afraid to contact your RV manufacturer directly for regulator replacement.


    A cover is required for every RV propane regulator to protect it from problem-causing factors such as rust or corrosion. However, some manufacturers do not supply covers with their regulator purchases, which might be inconvenient for customers.

    After all, if you buy a regulator without a cover, you’ll have to do more research and buy one separately. This method is not only inconvenient, but it is also completely unnecessary given the amount of wonderful brands that include a high-quality cover with purchase. As a result, do yourself a favor and purchase an RV propane regulator with a cover. Its inclusion will not significantly increase the price, and you will save time by not having to do further product research on the internet.

    Frequently Asked Questions

    What Is An RV Propane Regulator?

    An RV propane regulator guarantees that your RV’s entire propane system operates safely and efficiently. This involves regulating and supplying adequate propane to all of your RV’s propane-powered appliances, such as your central heating system, water heater, cooktop, and other appliances. Because your regulator supplies enough fuel to these appliances without blowing up your RV, we consider it a vital piece of RV safety equipment.

    How Do RV Propane Regulators Work?

    RV propane systems store liquid propane in a permanently placed ASME tank. Larger propane amounts can be stored in these tanks for RVs. An RV propane tank typically consists of a regulator and a fill valve.

    Because the liquid propane inside the tank can generate high pressure when consumed, it necessitates the use of a regulator. The liquid propane is dispensed at a safe level via a propane regulator. To avoid generating a dangerous spark, these regulators often use brass contacts and an aluminum body.A propane regulator typically delivers a working gas pressure of less than 1 pound. The existing gas pressure is decreased to a safe level due to the pressure spring riding on the diaphragm. The backpressure of the spring reduces the high-pressure propane flow in the tank.

    How Do You Know If Your Propane Regulator Is Bad?

    If you see indicators that your RV propane regulator is malfunctioning, it may be time to replace it. Some of the symptoms of a faulty RV propane regulator include insufficient propane reaching your appliances or burning through propane more faster than usual.

    If you recently placed a fully charged tank and all other indicators indicate that you should have propane to your appliances, you most likely have a propane regulator problem. As a result, you should absolutely read our reviews of the top RV propane regulator models.

    How to install RV propane regulators?

    Installing an RV propane regulator is not a difficult task; it is straightforward and requires little to no effort. But the best part is that you don’t have to hire a professional unless you’re not confidence in your talents. The actual operation does not necessitate the use of many tools, and most manufacturers will provide everything you need with the purchase of the regulator. Of course, some companies will not, which means you’ll have to buy the extra parts separately.

    Finally, the success of this experience is dependent on your ability to follow the directions in the handbook that comes with the regulator. If you find them to be clear and simple, you should have no trouble executing this installation yourself. However, if you’re like me and aren’t completely sure in your mechanical abilities, hiring an expert isn’t a bad idea. Furthermore, the cost of this job is not too expensive and should not deplete your financial account. In most circumstances, it is relatively inexpensive.

    How to adjust an RV propane regulator?

    Given the dangers of propane, all changes should be left to an expert, unless you are one yourself. I realize it will cost you some money, but investing a little extra is preferable to experiencing something truly horrible. With this in mind, contact a specialist to adjust the regulator. It is preferable to hire a professional rather than attempt a do-it-yourself remedy that may or may not solve the problem. Finally, there is a reason why people do things like this for a living.

    Can I Connect A Propane Tank To My RV?

    Yes! However, you will need the proper tools and adapters to make it happen. The good thing is that it isn’t extremely complicated, and you should be able to complete it on your own if you do your homework and double-check your work.

    How to clean RV Propane Regulator?

    Shut off the tank’s valve and remove the regulator, as well as the hose, when cleaning your propane regulator. Connect the hose and regulator to the tank after immersing the regulator in a mixture of soapy water.

    You must cover your two-stage propane regulator for proper care and protection. Most versions come with a plastic cover that can be used for this purpose. If your RV propane regulator doesn’t come with a cover, get one right away.

    If the vents aren’t clean, the regulator won’t work properly. Consider positioning the stage two vent downwards to keep the vents clear of dust and debris. Propane regulators for RVs should last a long time, but not indefinitely. Replace the regulator every 10-15 years to get the most out of it. Even though your propane system is still operational, the internal parts will ultimately wear out.
