In the camping world, It’s everyone’s goal to live a comfortable life on the road. You need a good propane regulator to control the gas supply for all your RV appliances, from stoves to heaters and fridges. It would be frustrating to wake up on a cold, freezing night due to a lack of propane supply.
The best RV propane regulator should optimize your appliances’ operation while keeping a constant gas flow at a safe level. There are various brands out there; that’s why I streamline your choices to 10.
- Design: RV propane regulators may come in different varieties, and your choice depends on your needs. If you own a high-capacity appliance, use a high-pressure regulator to meet such demand and a propane tank dual regulator for more stability. A first-stage regulator reduces pressure in one step while a second-stage model minimizes pressure in two steps.
- Capacity: The BTU rating determines the capacity of a propane regulator. Most of the RV propane regulators we reviewed below have a BTU rating between 160,000 to 500,000. For pop up camper, 50,000 BTUs seem enough to supply all appliances, while a big RV may benefit from a high flow dual propane regulator that can reach up to 1,000,000 BTUs.
- Other Features: The components of the regulator should be solid, including the hoses and fittings. To ensure that you don’t run out of gas, consider an RV propane regulator with gauge. An overfill prevention device is necessary to keep the tank safe from overflows.
Here are the top-rated RV propane regulators that you can try.

What To Know Before Buying An RV Propane Regulator
Shopping for new RV propane regulators is quite challenging if you lack knowledge about them. Before you visit the nearest local store or add a propane regulator to your cart online, take a look at this vital information you need to learn.
The Different Types Of RV Propane Regulators
Propane regulators aren’t built the same. They’re available in different types to suit your specific needs. Here’s a run-through of all these regulator types.
- High-Pressure Regulators
A high-pressure regulator is a safe connection to high-demand appliances that need pressure regulation. This regulator type is often marked with a red color and tends to be fused in a two-stage regulator system to indicate high-pressure modulation. These models can deliver up to 100 psi and even up to 10,000,000 BTU per hour.
- First Stage Regulator
Also known as single-stage regulators, a first stage regulator often comes with only one propane tank. These models are typically connected to a camping stove or gas grill to deliver low BTU ratings. The purpose of this regulator is to provide propane at a lower pressure level before it enters the gas line.
Now, you can’t install a first stage regulator without a downstream connection of a second stage regulator. The first stage regulator will make up for varying tank pressures and provide a pressure of not more than 10 lbs.
- Second Stage Regulators
The second stage regulator stands between the first stage regulator and the actual application. This type further reduces the propane tank’s pressure and ensures that it won’t overload the appliance with high gas pressure. These models may be linked to premium appliances and usually deliver about 175,000 BTU per hour.
Likewise, the second stage regulator can’t work without the first stage unit.
- Two-Stage Regulators
The two-stage regulators are what you commonly see in RVs. This type combines the first and second regulators to deliver a steady flow of gas in multiple appliances. Most models have an automatic changeover function to switch to the second tank when the primary one needs refilled.
These regulators are your most suitable option when your tank is far away from your appliance or RV. Since a two-stage regulator won’t deliver the propane that the demand of the appliances, a long connection from the tank to an RV with a total capacity of more than 1,000,000 BTU would benefit from this system.
Benefits And Drawbacks Of Propane Regulators
The RV propane regulator is crucial to your RV’s propane system. Without it, your appliances won’t work properly, even if your tank is full of propane. Its purpose is to moderate the gas flow and reduce the gas tank’s pressure to the appliances.
The regulator serves as a safety barrier between your appliances and the tank’s high pressure. Additionally, the propane regulator is relatively easy to install. The outlet and inlet fit different sizes, so you don’t get confused between them.
On the downside, an RV propane regulator may pose a serious risk when propane gas leaks occur. This gas may increase the risk of fire and explosion when it gets close to ignition sources.
The Basic Components Of An RV Propane Regulator
Features may differ from one regulator to another, but the essential components remain the same in many regulators. The basic parts and components of a regulator are:
- Body: This is the primary physical portion of the regulator, usually the lower part.
- Cover: Above the body is the cover, which is color-coded for its function type. For instance, red can mean high pressure.
- Inlet and outlet: These ports are where the gas vapor enters and exits the regulator.
- Lever: This part pushes up on the diaphragm when the vapor flows through the orifice, a piece that identifies the vapor amount that passes into the regulator.
- Diaphragm: Feels the pressure and controls the gas vapor flow.
- Vent: Designed into the cover to allow the regulator to breathe while it operates.
- Fittings: The oldest fitting type is the POL fitting, which requires a wrench to secure it. New propane models usually use hand-tightened Acme fittings, which are often designed with a safety mechanism that keeps the propane from leaking.
- Overfill Prevention Device: Also known as OPD, this safety component prevents the tank from overflowing with propane.
- Hoses: These components connect the propane tank regulator with the RV appliance. They’re either made from rubber or plastic and often enforced with a steel mesh for durability.
- Gauges: These components tell you how much propane remains in your tank.
What To Look For On A Good RV Propane Regulator
Sometimes, there comes a situation when your regulator gets crappy in the middle of your RV trip. If you want to shop for your own RV propane regulator, you must pay attention to these features.
- Material: You’ll want to check the propane regulator’s material so that you can evaluate its durability. The most durable regulators are made of zinc, aluminum, and brass. Look for something that’s powder-coated or built for heavy-duty.
- Capacity (BTU): A regulator’s capacity is measured in British Thermal Units (BTUs). The price of a regulator is usually dependent on the capacity: the higher, the more expensive the regulator becomes. But for RVs, they need not more than 50,000 BTUs.
- Accessories: Some of the top-quality models include many accessories, like a protective cover for dust protection. Others also offer hose and screws for easy installation.
- Automatic Change Over: If your RV uses dual propane tanks, look for a regulator with an automatic change over function. This feature allows your regulator to automatically shift from the bare cylinder to the full one, ensuring a ceaseless gas supply. When it’s time to refill the empty tank, you can operate a propane auto changeover valve without a regulator.
- Color Indicators: Most two-stage regulators have color indicators to tell you when the tank is empty or not. Red means that the tank has run out of propane, while green means it’s full.
RV Propane Regulator Troubleshooting Tips
The worst scenario that can occur to your vacation is to get regulator problems in your RV camp in the middle of a freezing night. Once this happens, here are some troubleshooting tips you can follow.
- If your RV propane isn’t flowing, check whether the propane valve’s on. Usually, a regulator has a 36-degree-turn handle or a half-turn knob; turn the valve clockwise. If it’s on, proceed to the excess flow valve.
The excess flow valve stops the gas flow when it detects a leak or you open it too quickly. Sometimes, the valve remains closed when you forget to screw the propane hose fitting correctly.
- If you smell gas, shut off the propane regulator system immediately. Check for leaks around the hose assembly, valve, and the regulator itself. Spray or paintbrush some soapy water into these parts. If you see some bubbles, that area leaks and needs to be tightened with a wrench immediately.
- If your burners produce uneven light and low heat, check the burners and look for holes. The problem is with your regulator if you find no holes on the burner. When the light is uneven, it’s time to replace your old regulator.
Frequently Asked Questions (FAQs)
How do RV propane regulators work?
RV propane systems use a permanently installed ASME tank to store liquid propane. These tanks can store larger propane volumes for RVs. Usually, an RV propane tank consists of a regulator and a fill valve.
Since liquid propane inside the tank can generate high pressure when consumed, it needs a regulator. A propane regulator dispenses the liquid propane to a safe level. Usually, these regulators use brass connections and an aluminum body to prevent generating a hazardous spark.
Generally, a propane regulator dispenses a working gas pressure of less than 1 pound. Due to the pressure spring riding against the diaphragm, the existing gas pressure is reduced to a safe level. The spring’s backpressure slows down the high-pressure propane flow in the tank.
Who makes the most trusted RV propane regulator?
Flame King makes the top-rated RV propane regulators because it usually produces the top-tier two-stage models, like KT12ACR6. Flame King’s two-stage regulators are easy to install as they already come with sturdy pigtails. Additionally, these regulators have color indicators to tell you when the tank is empty and automatically switch to the second full tank.
Other good contenders of propane regulator brands are Marshall Excelsior, Camco, and JR Products. These brands also offer sturdy two-stage regulators that can supply multiple appliances in your RV.
How do I know if my propane regulator is bad?
One of the symptoms of a bad propane regulator is the smell of propane. The unique propane odor you smell could clearly indicate that you have an RV propane regulator leaking from the vent or hose. Whatever the source is, quickly turn off the tanks and appliances. Keep away any lit cigarettes and put down nearby campfires.
Other signs that your propane regulator has gone wrong are when you see orange or yellow blazes, and hear popping sounds when turning on/off the tank. For these situations, you may need to conduct a minor RV propane regulator adjustment.
Remove the controller top and turn the screw, underneath the spring, clockwise. Turning the screw slightly makes a small weight increment modification.
Why is my RV propane regulator venting?
Maybe your tanks have simply overfilled. The extra spring heat might have swelled the gas and boiled off the excess propane. Try weighing the tank to check whether they went out of scale. The tank should weigh around 54-55 lbs when full.
Then, there’s a problem with the regulator itself. If it’s newly bought and still under warranty, you should contact its customer service to find a solution. Propane regulators have a lifespan, which may last up to a decade. When your propane regulator is venting/leaking, you might need to replace it with a new one.
How to set up and use?
Install the regulator on the ASME propane tank, not over 36 inches from the tank’s valve. Whatever regulator type you use, you must protect it with cover, like the tank dome.
When you install the regulator outside the dome, ensure that the vent is facing down. This setup will help prevent any debris, water, and snow from entering into the vent. Try putting a screen on the vent to keep the insects out of the unit.
Always turn off the valve when you fill your propane tank. Once the refill is done, turn the valve back on to fire up your appliances.
For propane regulators with an automatic dual tank changeover function, turn on both propane tanks. Switch the lever from the empty tank to the full tank. Many of these models have color indicators to show you that the tank is empty or full (red means empty and green means full).
How do you clean and care for a propane regulator for RV?
When cleaning your propane regulator, shut off the tank’s valve and remove the regulator and the hose. Submerge the regulator into a mixture of soapy water, then reconnect the hose and regulator to the tank.
For proper care and protection, you’ve got to cover your two-stage propane regulator. Most models provide a plastic cover to serve this purpose. If your RV propane regulator comes without a cover, get a new one immediately.
Keep the vents clean; otherwise, the regulator won’t work perfectly. To keep the vents free from dust and debris, consider positioning the stage two vent downwards.
RV propane regulators should last for a long time, but it doesn’t mean forever. To enjoy maximum performance, replace the regulator every 10-15 years. The inside parts will wear out eventually, even if your propane system is still working properly.
How to fix an RV propane regulator?
It’s not uncommon that an RV propane regulator goes out, especially when it’s old. The first thing to do is to perform some RV propane automatic changeover regulator troubleshooting. Check the gas tanks to see whether they’re empty and try to reset the excess flow valve.
You can also conduct a gas pressure test to determine if the regulator is working well. Disconnect the hose that feeds propane into the RV and turn off all propane appliances. Insert a rubber adapter to the port whose hose you disconnected and connect the gas pressure test kit. Replace the regulator if it’s not working.
Another quick fix is to thaw the propane gas regulator, especially when it’s cold because the gas can freeze and stop flowing. To fix this, remove the regulator from the tank and leave it disconnected for 30 seconds. Reconnect the regulator after the time has passed.
Do I need a high or low pressure propane regulator?
Choosing the right RV propane regulator pressure depends on how much BTU your appliances actually need per hour. It’s not advantageous to get a high-pressure regulator even if you need less because it makes it difficult to control. The rule of thumb is to get a regulator that’s close to what your appliances need.
Outdoor gas appliances like fish fryers require a high-pressure regulator to flow a high volume of gas. The output of this device can reach up to 10,000,000 BTUs per hour.
You’ll need a low-pressure regulator if you own a low-capacity and demand appliance like a camping stove or gas grill. This type of regulator has a BTU output of around 70,000.
How long does an RV propane regulator last?
A propane regulator for camper should last around ten years. After a decade, you’ll notice a few issues like leaks, popping sounds, and being unable to switch over to the other tank if you have dual propane tanks. It’s better to replace the unit at this time.
1 stage vs 2 stage propane regulator: what is the difference?
An RV LP regulator can be a one-stage or two-stage variety. A one-stage regulator minimizes the pressure in a single step, whereas a two-stage model does it in two steps. This makes the flow of a two-stage regulator more stable and reliable.
While an end-of-tank dump is common in one-stage regulators, a two-stage regulator doesn’t have that problem. An end-of-tank dump occurs when the tank pressure declines to a certain level that the regulator ceases to regulate, hence dumping the rest of the propane.
Where to purchase an RV propane regulator near me?
Online stores like Amazon offer many brands of RV propane regulators at reasonable prices, while physical stores can let you see the actual product.
Some RV manufacturers like Airstream also provide RV propane regulators for their customers. Make sure that you keep yourself updated on any parts recall because you can ask your RV dealer for replacement.
It’s definitely a must to get an RV propane regulator for your appliances’ optimum performance. The 10 propane regulators I reviewed above are perfect options, but the Flame King KT12ACR6 slightly stands out as the best RV propane regulator. This model ensures that you don’t run out of propane as it automatically switches from the empty cylinder to the full one.
For quality and safety, the Marshall Excelsior MEGR 253 is an excellent option as it passed all standards from NFPA, RVIA, and UL. Now, I recommend the Camco 59313 if you want to ensure a leak-proof connection. The GR-630B and JR Products 07 30325 are your best bet for budget-friendly options.
