After all, RV’s and traveling are as American as apple pie and baseball. And, even if you aren’t from America, taking a tour of your country by driving through its winding streets probably makes for a great vacation.

What Is a Propane Regulator?



Not only does it control flow, but it also lowers the pressure of the gas coming from the LP (liquified petroleum) gas tank.

These are both immensely important tasks the regulator must complete if you’re going to be safe while using propane.

It’s also key to understand the difference between a two-stage regulator and a single-stage regulator. A two-stage regulator reduces cylinder pressure in two steps while a single-stage regulator does so in one.

So, a two-stage regulator is useful when you’re not changing the pressure constantly. If you find yourself changing the pressure on a consistent basis, a one-stage regulator is the best choice.

So, you now know what a propane regulator is. But, why do you need a propane regulator for an RV? How does it differ from other types of appliances?

Why You Need a Propane Regulator for Your RV

RV’s almost function the same way as a mini-house. Typically, they have a kitchen area, a bathroom, and a small living space as well. Whether you’re heating your RV, taking a hot shower, or cooking, using propane means you need to regulate it.

If you don’t, you could easily access too much of it and cause an explosion.

It’s also important to have because it sits at the heart of the propane system inside your RV. And, without the best RV propane regulator, not only do you get dangerous amounts of pressure from the propane but you also may not even get it to function.

So, a propane regulator is crucial to the RV. If it doesn’t work, then everything else in the RV gets affected as well.

Where You Can Buy Propane Regulators for RVs



The best RV propane regulator sits on shelves in a multitude of stores. Wal-Mart, Lowe’s, and Home Depot are three physical stores that have these items readily available.

Online, sites such as Amazon and eBay also carry them.

How We Chose the Best Propane Regulators for RVs



The best RV propane regulator carries a couple of qualities. First, it has to hit 100,000 BTU (British Thermal Units) at least. This number equates to the amount of energy it takes to raise one gallon of water one degree Fahrenheit.


This number is crucial because you can use this information to determine how long you’ll be able to heat things. It’s similar to a car and its “miles-per-gallon” ratio.


Second, all of these propane regulators score at least 4 stars out of 5 stars on Amazon. Customer reviews play a significant role in determining how well a product is performing in the market.


Taking these two factors into account gets you a list of what many consider to be the best RV propane regulators money can buy.

Mr. Heater F273763 Two Stage VericalPropane Regulator 1/4" Female...
  • Propane lp low pressure regulator
  • 2 stage
  • Consistent gas flow

The best RV propane regulator needs to provide a consistent gas flow. If the gas doesn’t come out smoothly and with consistency, time in the RV will be spent fiddling with the regulator instead of enjoying time with friends and family.

Mr. Heater makes sure you have a consistent gas flow. One of the ways they do this is to reduce the size of propane that feeds into it.

At only a 160,000 BTU maximum flow, it may seem like a waste of time to look into this regulator. But, a smaller amount of propane doesn’t equate to a worse experience.

It’s also essential to take into account that this regulator is a two-stage regulator. By making a two-stage propane regulator, delivery pressure is constant. Mainly, that means you don’t have to worry about readjusting certain levels of the regulator.

A propane regulator that runs itself is a great find, and Mr. Heater delivers on this aspect.

Marshall Excelsior MEGR-253 Reg 2-Stage Auto Vert Bulk
  • Type: Two Stage
  • Max Inlet Pressure: 250 PSI
  • Inlet Connection: 1/4" Female Inverted Flare

When you begin your search for the best RV propane regulator, knowing the specifics of the item is key to understanding how exactly it works. For example, knowing if it’s a two-stage regulator or a one-stage regulator is immensely helpful. But, digging deeper into the tinier details reveals how the regulator will hold up over many different situations.

Take, for example, the detail of both the inlet and outlet connection. These connections occur between the tank and regulator, and it’s essential to know the sizes of these connections. Varying sizes apply to different types of regulators and tanks.

The MEGR-253 contains a 1/4-inch female inverted flare for the inlet connection and a 3/8-inch FNPT for the outlet connection. Making sure these connections match the size of your regulator and tank is the difference between a successful buy and a failed buy.

Along with these details, the MEGR-253 Two-Stage Regulator has a raw zinc/powder coat.

Cavagna Kosan 924N RV Auto Changeover Regulator w/RV 'L' Bracket
  • Inlets: (2) 1/4" Inverted Flare - Outlet: 3/8" Female NPT
  • 220,000 BTU Capacity
  • Stainless Steel Screws & Bolts

The Cavagna Group are known for making quality products. This high praise is backed up by their 924 N Auto Changeover Regulator.

The best RV propane regulator needs to be tough and sturdy. After all, you don’t want your regulator to fall apart after years of use. With the 924 N, that thought will never cross your mind. Why?

Well, Cavagna decided to use stainless steel screws and bolts with this regulator.

Some other companies may skimp on this aspect, but keeping your items protected against wear and tear is just as important as how well the regulator performs.

A high-temperature resistant diaphragm helps measure the pressure given off from the regulator. It’s a critical piece of a regulator, and you need it to be strong if it’s going to withstand different types of weather environments.

Containing a 220,000 BTU capacity, it’s a little on the smaller side. But, with all the other positive aspects, this shouldn’t put too much of a damper on the regulator.

Camco makes some of the finest quality propane regulators you can find on the market today. 

One of the positive attributes that stick out about this regulator is the outlet pressure. Its outlet pressure is 11 WC, which is the standard pressure, so you know you’re not going to be disappointed in this regard.

With only 160,000 BTU it is a tad smaller than other regulators. But, a more significant volume of BTU doesn’t mean a better regulator. This one, with the pressure it’s working with, performs just fine.

Since this is a two-stage regulator, you don’t have to worry about pressure building up.

These attributes make for a propane regulator that gets the job done. Whether you’re using it for the first time or the hundredth, you’ll always get a consistent and quality result.
