What is a propane regulator for RV?  

An RV propane regulator is a mechanism that you connect to your propane tank’s shutoff valve. Its main function is to regulate the gas flow to the appliances in your RV that’s powered by your propane tank such as the oven, stove, furnace, outdoor grill, refrigerator, and water heater.

A propane regulator for RV is an extremely important safety feature. It controls the gas flow in your camper. As we all know, anything that deals with gas inside a vehicle should be safely handled and monitored to prevent leaks and a possible explosion. This is an extremely dangerous situation that we should try to avoid at all cost.

That is why you need an RV propane regulator to ensure your safety in your camper. It monitors the propane pressure level in your propane tank and make sure that it is within a safe level. This will ensure that all your devices onboard that run on propane gas are working properly and safely.

It is important that you keep your RV propane regulator in good working condition because it is your key to the proper functioning of your propane tank and propane-powered appliances. It doesn’t matter if your propane tank is full if your propane tank regulator is not working properly. This also means that your safety inside the camper is compromised.

With this information, we have established the importance of having an RV propane regulator. It ensures your safety, comfort and convenience inside the rig. This is why you should get yourself a good quality RV propane regulator.

How does a propane regulator work? 

An RV propane regulator is a relatively simple device. Its main parts include the inlet, outlet, the vents, and the docking mechanism. RV propane regulators also need a cover. This is usually made of plastic. Some regulators already come with a cover. For those that don’t have a cover, it is recommended that you buy one.

The propane regulator works by using a combination of diaphragm and pressure spring to regulate the gas pressure. The moment that the gas from the propane tanks is released, the propane regulators go to work to make sure that the gas pressure is kept at a reasonable level and then they forward the gas to the appliances that they are connected to so that they will have power.

Take note that the gas pressure directly from the tank is extremely high. It is around 100 to 200 psi with some even reaching 250 psi. This is a dangerous level that’s why you need an RV propane regulator to bring it down to a manageable level between 10 to 15 psi- big difference right?

To do this, you just have to turn off the regulator valve as you’re filling up your propane tank. When it is full already, you can turn the valve on. It is now ready to power your appliances.

For those with two propane tanks in your rigs, you don’t need to buy a separate regulator for each one. You can use an automatic dual propane tank regulator instead. This allows you to control both propane tanks with the help of the regulator’s lever.

When you’ve got a propane regulator that’s working properly, you wouldn’t have to worry about your RV appliances not functioning. You won’t experience running out of gas in the middle of nowhere and wouldn’t have to bear the discomfort that it brings. All you have to do is make sure that your propane tanks are full and your regulator will take care of managing the gas flow to your appliances.

Types of Propane Regulators for RV

Here are the main types of propane regulators in the market that you need to know so that you can choose the best RV propane regulator. You have to have a basic understanding of these types because each one is intended for a different purpose so you need to choose the type that will fit your specific needs.

First or Single Stage Propane Regulators

This is not for RV use so you shouldn’t get yourself a first or single stage propane regulator. This type of regulator is used for smaller level of application such as a portable campfire or barbecue grill.

If you use a first or single stage propane regulator for your RV, you won’t be able to control the gas pressure and this is very dangerous.

Double or Two Stage Propane Regulators

Most RVs use this type of propane regulator. The two stage propane regulator is capable of managing the propane needs for all your appliances inside the camper. This includes your stove, oven, water heater, furnace, refrigerator, among others.

If you have a larger rig such as a Class A motorhome, you can opt for a high flow version of the second or two stage propane regulator. This version will efficiently power multiple furnaces, outside kitchens, and other accessory connections that you have in your rig.

Automatic Dual Tank RV Propane Regulators

If your RV uses two propane tanks, you should get an automatic dual tank regulator. It will allow you to control those tanks with the use of a lever which is located on the regulator itself. Now you can enjoy continuous supply of propane for your appliances.

To summarize, the 3 types of propane regulators are the first or single stage propane regulator, second or two stage propane regulator, and automatic dual tank regulator. It just shows that you should choose the right type based on your RV propane tank. If you have a single tank, then you should buy a second or two stage propane regulator. If you have a dual tank, get an automatic dual tank regulator. But don’t ever buy a first or single stage propane regulator for RV use.

Knowing this information is a great help when looking for the best RV propane regulator.

Benefits of Propane Regulators

To further seal the importance of having an RV propane regulator, here are the specific benefits that you’ll be enjoying by simply using one in your rig.

Safety

First and foremost, for safety reasons. Safety should always be our top priority. An RV propane regulator ensures your safety by making sure that the gas flow in your rig is kept at a minimal and safe level.

As mentioned earlier, the gas coming directly from the tank has a pressure of 100 or even up to 250 psi which is very dangerous. We need to keep it down to only 10 to 15 psi and that is what propane regulators are for.

An RV propane regulator will ensure that you can power your RV appliances safely, reducing any risk of damages or explosion to your gas-powered devices such as your stove, oven, furnace, water heater, and refrigerator.

Make sure that your appliances are working properly

Without an RV propane regulator, your appliances won’t work effectively. If you don’t have one in your rig, you could encounter issues that would have damage your appliances because of the unregulated flow of gas.

An RV propane regulator will ensure that your RV appliances are functioning well by distributing adequate amount of gas that they need to keep running.

Save money

A good quality RV propane regulator will save you a lot of money. Since it regulates the amount of propane being used in your rig, you don’t waste any propane and use just enough as needed to power your RV appliances.

And if your appliances are working properly, you won’t have to spend money over repairs and replacements.

Convenience

When your RV appliances are working as they should, you get to enjoy the comforts and conveniences they bring no matter where you are.

You get to store food in your refrigerator, cook your meals over the stove or grill, and stay snug and comfy even when it’s cold outside with the help of your heater.

These are the benefits of using an RV propane regulator. You have peace of mind because you know that your rig is safe. Your appliances will work properly thus you’ll enjoy the comforts and conveniences of having them. And you’ll save money because you are using your propane efficiently and you won’t have to pay for costly repairs and replacements.

How To Pick Up The Best RV Propane Regulator

The benefits we’ve discussed above reiterate the fact that you need to get yourself a good quality RV propane regulator. That is why you should take your time in choosing the best RV propane regulator. Here are the top considerations you have to make when buying a regulator.

Capacity

The RV propane regulators that you’ll see in the market will have different BTU capacity. This is relevant because it determines the amount of gas that your appliances need to function properly.

There are appliances that need a high level of BTU so your propane regulator must be able to let out that much gas to be able to power those appliances. The higher the BTU, the more propane your regulator will release.

Just a heads up, propane regulators with a higher BTU capacity are more expensive. But it is important to get one that has the capacity to provide your propane needs. Because if you get a regulator with a low amount of BTU, your RV appliances won’t be able to get the right amount of gas that they need in order to work properly.

That is why you need to know the BTU requirements of your RV appliances so that you can buy the appropriate regulator for them. Then, you should balance this with the budget that you have set. Get the propane regulator with the highest BTU capacity that’s within your budget.

It is safe to get an RV propane regulator with a capacity of 50,000 BTU. This should be enough to power all your appliances onboard. But you can get one with a lower or higher capacity depending on your propane-powered appliances.

Quality

As we keep mentioning above, you should get yourself a good quality RV propane regulator. Whenever your safety is concerned, it is best to invest in a product that’s built from quality materials so that you can rely on it to get its job done effectively.

Will you get a regulator that’s made of brass, raw zinc, aluminum, or stainless steel? To give you an idea, the best RV propane regulators have a lifespan of 15 years. For them to last this long, they should be made of durable materials. Look for a regulator with a heavy duty construction so that you know that it can withstand the test of time. They should be able to resist rust and corrosion.

You can also read the customer reviews regarding their feedback on the quality of the product. Watch out for reports about product malfunctioning or those that break easily. For sure, you’ll read lots of feedback regarding the product’s quality. Customers will definitely rant when they’re not satisfied with the quality of the regulator that they bought.

Ease Of Installation  

RV propane regulators shouldn’t be too hard to install. You won’t be needing professional assistance to put this in place.

But there are some models which can be complicated to install. For example, there are some automatic dual propane regulators that don’t come with a mounting hardware. This can make the installation process harder. This is why you should buy a regulator that requires no tools for installation or one that comes with all the tools and hardware that you need to complete the process immediately.

This is where it’s helpful to read the customer reviews as buyers usually share their experiences regarding the installation of the product. This will give you a good idea if they had an easy time in connecting the regulator to their RV’s propane tanks.

Maintenance

Your propane regulator needs maintenance so that you can be sure that it continues to do its job effectively. With that said, you should look for one with a simple maintenance procedure so that you can do it yourself.

You can do a quick research regarding the maintenance procedure from the manufacturer’s website or check the customer reviews for feedback from the users themselves.

Covers

As mentioned earlier, your RV propane regulator needs to have a cover to protect it from harsh elements. A cover will reduce its exposure to harmful particles. This will help prolong the lifespan of your regulator as it fights off rust and corrosion.

It is good if the regulator that you’re buying already comes with a cover so that you won’t have to buy one separately.

Price

If you’ve been browsing the internet for the prices of RV propane regulators, you’ll notice that most of them are offered at an affordable rate. On the average, they cost around $30 per unit. This is a reasonable price considering the benefits that you’ll reap.

But of course, there are regulators available at various price points – other manufactures will lure customers with a very cheap price or some will promise enticing features to justify the expensive price.

Like we always say, look for a balance between price and quality. Don’t go for the cheapest one out there because chances are, the quality of the product is compromised. As for the more expensive regulators in the market, ask yourself if you really need those added features.

As we mentioned earlier, the higher the BTU capacity, the more expensive the regulator. But the thing is, do you need a regulator with this kid of capacity? How many appliances do you have in your camper? How much BTU do they require to work properly? If you don’t need a high capacity regulator, then it is wise to choose the regulator with a lower BTU capacity which comes at a more affordable price.

This will help you stay within your budget. Set a price limit before looking for the best RV propane regulator and stick to that range. You will also find it easier to buy a propane regulator when you have a specific budget in mind.

Wrap Up

An RV propane regulator is essential in your RV life. This simple device can do a lot in protecting you from gas leaks and possible explosion and fire inside your rig.

Ensuring your safety on the road is priceless plus you get to enjoy the other benefits of having a propane regulator in your rig.

This is why it is important to get yourself the best RV propane regulator out there. Use all the information we’ve provided here to guide you in making a purchase.
