There’s an overview of the 10 Best RV Propane Regulators on Amazon. Before you decide which is the one for you, here’s some background information on the science and purpose underlying each of the specific types of RV regulators covered in our review.

Propane tanks in RVs come in three basic types:

  1. Vertical propane cylinders found in travel trailers, fifth wheels, and vans.
  • Large ASME horizontal tanks found permanently installed in Class A and Class C motorhomes.
  • Small portable propane cylinders typically used to fuel outdoor appliances like grills and fire pits.

All three tank designs can be found in RVs of various types. Each requires a specific propane regulator (aka a gas valve).

  • Type #1 needs a vertical two-stage auto-changeover propane regulator or a standard vertical two-stage regulator.
  • Type #2 needs a horizontal dual-stage propane regulator.
  • Type #3 needs a low-pressure (single-stage) propane regulator.

What Does An RV Two-Stage Propane Regulator Do?

A two-stage propane regulator reduces the gas pressure from a propane tank in two stages to safely supply low-pressure gas appliances inside the RV. The first stage reduces gas pressure from above 180psi to approximately 13psi, while the second stage cuts pressure to 0.4psi, or an 11” WC rating.

In a nutshell, a propane regulator harmonizes the propane supply tank with propane appliances. A high-pressure propane cylinder feeds gas into hoses that lead to your cooktop and oven, refrigerator, furnace, and water heater in your RV.

  • Without a two-stage regulator plumbed directly into the propane system at the main ‘house’ tank, each propane appliance would be an inferno.

The two-stage propane regulator ensures the correct amount of gas pressure and delivers the required volume of propane to each RV appliance. The unit of measurement that the regulator and gas appliances share to ensure compatibility is BTU (British Thermal Unit).

Each RV propane appliance will have a specific BTU demand, which the regulator must satisfy if the appliance is to function correctly.

An RV two-stage regulator must supply sufficient BTUs to power several propane appliances simultaneously.

  • The higher the BTU rating on an RV two-stage propane regulator, the better it will power your gas appliances. 
  • All RV two-stage regulators are set to a standard 11-inch WC (Water Column) rating and are not adjustable.

There are three types of two-stage regulators suitable for RVs. Let’s have a look at them. 

What Are The Three Types Of RV Two-Stage Regulators?

Two-stage regulators for RVs include the following types:

  • The standard vertical two-stage regulator
  • The auto-changeover vertical two-stage regulator
  • The horizontal two-stage regulator

Vertical regulators are fitted to DOT propane cylinders, while horizontal regulators are fitted to ASME tanks.

The propane regulator suitable for your RV will depend on the kind of propane tanks in your mobile home. Standard vertical two-stage regulators are ideal for single-cylinder systems, while a dual-tank system can be equipped with an auto-changeover vertical regulator.

A horizontal ASME tank must be fitted with a horizontal two-stage regulator.

A standard vertical two-stage regulator and a horizontal two-stage regulator work exactly the same way but mounted differently.

An auto-changeover vertical regulator differs from the other two types. It has an internal switching device that senses when one tank is empty and automatically switches the valve opening to allow gas from the full tank to enter the gas line feeding the RV.

The auto-changeover regulator has an inspection window that indicates when a tank is empty. A lever on the regulator allows the empty tank to be closed to optimize pressure in the gas system.

When the auto-changeover regulator draws gas from the reserve tank, the empty tank can be removed and filled without the RV moving from its location.

An auto-changeover propane regulator brings valuable convenience to RV life by automating the switchover procedure from one propane cylinder to another.  

What Is A Low-Pressure Propane Regulator?

Low-pressure propane regulators regulate high, fluctuating gas pressure exiting a gas cylinder, reducing pressure to a specified level where a gas appliance can safely use the propane. RV low-pressure propane regulators typically power cookers, fire pits, fridges, and lanterns.

Most propane appliances inside an RV come with a standard built-in low-pressure propane regulator. Aftermarket low-pressure propane regulators are typically used to fuel outdoor appliances like propane fire pits and grills.

A low-pressure propane regulator can be hooked up to a small portable propane cylinder or pipe gas directly from the RV house tank/cylinder using a brass tee adapter that serves as an auxiliary inlet/outlet for the propane system.

  • The tee adapter allows a backup portable gas cylinder to plug into the house gas lines, enabling extended camping when the main propane tank runs dry. A low-pressure regulator isn’t needed because the existing RV regulator will manage the gas pressure inside the vehicle.
  • The tee adapter allows a long hose to run from the RV tank to an outdoor fire pit or grill. The low-pressure regulator will be needed if the appliance doesn’t have a built-in regulator because the tee adapter sits upstream of the RV’s two-stage regulator.

Because dual-stage propane regulators differ in type according to the kind of propane tank in the RV, it isn’t easy to choose one as the overall best.

However, because the auto-changeover vertical regulator is so standard in the RV community and offers unmatched convenience, we’re going with:

Our best RV auto-changeover is JR Products 07-31525. Its solid build quality, impressive BTU rating, ability to handle cold weather, and reliable switching mechanism give it the nod.

Good luck, and happy camping!
