What Is a Propane Regulator for RV?

Propane is the most commonly used energy source by RV owners. It allows them to do everything from heating to cooking and more. It’s the preferred fuel type since it’s cheaper than gas and there’s no shortage of it wherever you go. And most RVs and trailers today provide propane hook up either through a generator or without one.

Most RVs, travel trailers, and 5th wheels use a dual tank propane system. These recreational vehicles usually have larger appliances and this means higher demand for propane. And an essential part of a propane system is a propane regulator that controls the flow and helps in the safer use of propane. Its primary function is to adjust the flow of gas according to the demand placed upon it. Without it, there’s a risk of fire since there’s nothing to control the gas flow coming out of the tank.

What sets apart RV propane regulators from standard ones that you might use in other applications is that they usually come with preset pressure levels that are more acceptable for RV use. Moreover, most of the RV propane regulators are also made with a 2-stage design, which regulates the pressure in two stages and brings it down to a safer and more adequate level.

A propane regulator is not an overly complicated unit. It consists of only a few parts, which include an inlet, an outlet, a vent, and a docking mechanism. Some regulators also include a plastic cover that protects it against elements.

How Does a Propane Regulator Work?

The purpose of a propane regulator is to control the high pressure gas that flows from the tank and to reduce it to a safer level. They can differ in size and shape. And they can also deliver different pressure and adjustability. However, despite all these differences, they for the most part have a very similar design.

Typically, a propane regulator consists of a restricting element, loading element, and measuring element. The first one comes in the form of a valve and its function is to restrict the variable flow of gas. The second element is used to apply the needed force to the restricting element and it usually comes in the form of a diaphragm with a spring. The measuring element is used to determine if the inlet flow is equal to the outlet flow. And this function is usually achieved by the diaphragm as well.

Types of Propane Regulators

There’s a wide variety of propane regulators available on the market and it’s important to choose the right one for your particular application needs. And to do that, it’s essential to understand the different types of propane regulators that you can choose from. Each of them has a different application purpose, so one might be more appropriate for you than the other. The following three are the most common types used in RVs.

1. Single Stage Regulators

This type of propane regulator is more suitable for smaller applications and is less common in RV propane systems. For instance, you could use a single stage propane regulator with a barbecue grill, a portable campfire, or other smaller appliance.

They are installed on a single smaller sized propane gas tank and then connected via a hose to the service valve. Moreover, they are also sometimes called low BTU regulators since they usually offer no more than 200,000 BTU capacity.

Single stage regulators are recommended for applications where it’s not as important to have constant outlet pressure. And this is what makes it not the best choice for RV propane systems since the erratic pressure levels can be damaging.

Two-Stage Regulators

Two-stage regulators are the most common type used for RV propane systems. They work in two steps to achieve a more constant pressure delivery without the need for monitoring or readjusting.

2. Automatic Changeover Regulators

One more commonly used type of RV propane regulator is the automatic changeover type. It’s used with dual tank systems, connecting to both of them simultaneously. However, first, it directs the gas flow from one tank and when that supply finishes, it redirects the flow from the second tank. This results in a continuous flow of gas without any interruption in service.

Why You Should Use an RV Propane Regulator?

A propane regulator is an essential part of RV equipment and that’s why it’s important that you also invest in one. And here are the four main reasons why you should invest in one for your RV propane system.

  1. Reduced propane pressure. Propane tanks are filled by forcing gas into them under high pressure. Due to this, when you connect it to an appliance, it releases the gas under high pressure as well. However, most appliances can’t properly operate under such high pressure and that’s why it becomes important to have a regulator that can reduce the pressure to a safer level.
  2. Dealing with varying propane gas demands. The purpose of a propane regulator is also to adjust to varying demands of the applications since smaller appliances will need a smaller supply of gas and bigger appliances will need more gas. In both cases, a propane regulator will be able to provide a constant supply of gas even when the demand fluctuates.
  3. Provides safety. Without a propane regulator, you’ll be getting dangerous amounts of pressure from the propane tank. And this can be dangerous, leading to fire and damage. That’s why you should have a propane regulator that would be keeping the propane gas pressure at safe levels.
  4. Getting a continuous supply of gas. It can be really frustrating when you’re preparing a meal or trying to heat your RV and all of a sudden you run out of gas. To prevent this, you can install an auto changeover propane regulator on two tanks. If you run out of gas in one tank, you’ll still have the reserve gas in the second tank. And due to the automatic changeover design, you won’t have any interruption in the supply.

Factors to Consider When Buying the Best RV Propane Regulator

It’s important not to rush when choosing the best RV propane regulator. It’s better to start by doing a bit of homework and understanding all the different features that these products come with. By taking these factors into your buying decision, you’ll be able to buy an RV propane regulator that would be ideal for your particular situation.

Construction Quality

A regulator is an essential safety feature of a propane system. That’s why it’s important to invest in one that is solidly built using durable materials. This will ensure that it will be able to withstand the elements and changing temperatures.

The highest quality materials that are usually used in propane regulators include raw zinc, aluminum, brass, or stainless steel. All these materials provide a rugged construction of the regulator and ensure its long lasting performance. Also, these materials offer protection against elements, preventing the unit’s rust and corrosion.

Most propane regulators usually don’t last more than 15 years, though auto changeover ones last even less. However, if there are any issues with a regulator, it can’t be repaired and it will need to be replaced at once. That’s why it’s important to choose a more durable product, so you won’t have to replace it that often.

BTU Capacity

Another important factor to consider when buying a new RV propane regulator replacement is its BTU capacity. This capacity refers to the amount of gas that is allowed to flow to appliances. So, a higher rating means more gas reaching your appliances. This is an important factor since without sufficient BTU capacity, your appliances won’t have enough gas to operate.

When choosing the right BTU capacity, try to determine your propane needs. The more appliances that you need to power with propane, the higher capacity you should look for. However, at the same time, higher capacity means a higher price. So, try to find a balance between the BTU value and your budget. You don’t want an overly expensive piece that would provide you with more BTUs than you need.

Ease of Installation

Most propane regulators are fairly easy to install. In most cases, it’s something you can do yourself without the help of a professional. However, there are still factors that can make the installation process either simpler or more difficult.

One thing that can make the installation easier is if the regulator comes with all the mounting hardware included in the package. This will mean that you won’t have to spend more time searching for the right hardware that would fit this particular unit and instead, the piece will be ready for use right out of the box.

Another thing to look out for is the installation instructions provided for the regulator. Some of the cheap brands don’t even include any instructions, so the buyer is left guessing. And improper installation can lead to issues in its operation, so it’s something you want to avoid.

You can get an idea of how difficult or easy it is to install a particular regulator by checking user’s reviews. From them, you can get a clear idea of the process and you’ll see if there are any complications to be expected.

Automatic Changeover

If you’ll be installing a propane regulator on an RV propane system, it’s better to choose the automatic changeover type. The benefit of this type of regulator is that you can have a constant supply of gas. Such a system is especially beneficial for situations when you spend long periods of time RV camping far away from stores where you could buy a propane refill.

You connect it to two propane tanks and at first, it uses the propane supply from one tank and then without interrupting the flow switches to the supply from the second tank. And while the regulator is directing the flow from the second tank, you can remove the first tank for refilling.

LED Indicator

If you’re using a two tank propane system, it will also benefit you if the regulator comes with an LED indicator. This indicator will make sure that you don’t run out of gas in both tanks. It works by turning the indicator to red color when one of the tanks is empty. If it’s an automatic changeover regulator, you can then remove the empty tank for refilling, while the second tank will continue supplying gas.

Protective Cover

One more important feature of a propane regulator is a plastic cover. It’s a useful feature for protecting the piece against rain and other elements, which could cause rust and corrosion.


As when shopping for any other product, it’s also important to consider the price of the propane regulator. Most of these products are fairly affordable but still, you don’t want to spend more than you need.

Some manufacturers add extra features and this makes the price go up. For example, a regulator with a higher BTU capacity will cost more. However, those extra features might not be as important for your particular application. That’s why it’s important to find the perfect balance between value and money.
