Best 2 Stage Dual Adjustable RV Propane Regulators 2020

What Are RV Propane Regulators?

The propane regulator is one of the most important parts of any LP propane gas system. It’s what controls the pressure coming out of the propane tanks and keeps your propane appliances running properly. All RV’s and many other appliance-based propane systems require 2-stage propane regulators. For more information on how 2-stage propane regulators work check out this article here.

If your RV propane regulator has gone bad you will need to change it out for a new one. (For how to tell if an RV propane regulator has gone bad check out this article here).  The good news is all propane systems on RVs and travel trailers have a standard system and use the same size of outlets and inlets. That means you don’t have to buy the exact regulator your RV came with to replace it.

You can get a regulator with a higher BTU capacity or even one with more waterproofing features, the choice is up to you. I’ve found and reviewed some of the best 2-stage RV propane regulators out there for dual propane tank systems. All of them have automatic changeover functions and are adjustable. You may even find the same regulator that came with your RV or travel trailer.

Either way, there’s an option to fill every RV propane regulator need.

RV Propane Regulators Reviews and Info


Flame King 2-Stage Auto RV Propane Regulator

Flame King (KT12ACR6) 2-Stage Auto Changeover LP Propane Gas Regulator With Two 12 Inch Pigtails For RVs, Vans, Trailers

Check Price at Amazon

The Flame King is a very popular LP gas regulator in the camping world. A lot of RV and travel trailer companies put them on their products right out of the factory. Our travel trailers propane regulator is a Flame King and it was easy to replace it with a new one when we started having issues.

For detailed instructions on how we changed our RV propane regulator check out this post here.
It’s a 2-stage dual automatic changeover regulator and a nice feature is that it comes with pigtails (the ends that go directly to the propane tanks) already attached. The plastic rain cover which is the white plastic part on the front is also included as well as a mounting bracket.

Flame King (KT12ACR6) 2-Stage Auto Changeover LP Propane Gas Regulator With Two 12 Inch Pigtails For RVs, Vans, Trailers

In order to run your camper’s propane appliances, you must have a 2-stage regulator. The Flame King comes pre-set at the proper pressure but is also adjustable. You should never have to adjust it but the option is there.

The automatic changeover function works seamlessly. Just make sure both your propane tanks are open and when the primary tank is empty the RV propane regulator will automatically switch over to the other tank. The clear window in the center of the regulator will now be red indicating that the primary tank is empty.

You can choose what tank you want to use manually by using the small black lever that has an arrow on it. Whatever direction it’s pointing will be what tank it will draw from first. Make sure to point the arrow down when removing the propane tanks.

The inlets are ¼” SAE inverted flare and the outlet which is the part that attaches to the main RV gas line is 3/8” NPT. Both sizes are the standard for RVs and travel trailers so it should be compatible with your RV’s propane system and tanks.  The propane regulator is also rated at 190,000 BTU which is plenty for the needs of RV appliances.

The Flame King 2-Stage Auto RV Propane Regulator is easy to install and no nonsense. I’ve been very impressed with it and I haven’t needed to adjust it. It’s a great replacement for any RV dual propane tank LP gas system. The automatic feature comes in handy as well on a cold morning when you need to run your furnace. You don’t need to worry about the tank running out of propane and have to run outside and manually change it over.

PROS

  • Automatic Changeover
  • Empty Propane Tank Indicator
  • Comes with Dual Propane Tank Pigtails
  • RV Bracket Pre-Installed
  • Comes with Rain Cover
  • Adjustable

Marshall Excelsior RV Propane Regulator

Marshall Excelsior MEGR-253 Reg 2-Stage Auto Vert Bulk

Check Price at Amazon

The Marshall Excelsior is another RV propane regulator commonly found on travel trailers and RVs. The regulator doesn’t come with any pigtails or a mounting bracket. You will either must buy new ones or use the bracket and pigtails from your old RV propane regulator.

If you need to get new pigtails you can buy some on Amazon here.

If you need a mounting bracket you can buy one on Amazon here.

The Marshall is nothing fancy, but it gets the job done. It’s 2-stage which is a must have for an RV and it has an automatic changeover. What I like about this regulator is the indicator that shows if the primary tank is empty is located on the top.

On other styles of automatic propane regulators, you need to take the time to look at the side to see if it’s red or not. With the Marshall, you can see the red right away. It also shows green when the propane tank still has gas in it.

There is no rain cover, but the outside is finished with a durable powder coat. If you have a rain cover for your propane tanks or they are enclosed, you won’t need to worry about a rain cover for your propane regulator anyways.
It is adjustable if you ever need to use that function and this version is for up to 150,000 btu which is just enough for a camper or travel trailer.

The inlet connectors are the standard 1/4” female inverted flare and the outlet connection to the main RV gas line is 3/8” NPT. Much like the other RV LP gas regulators on this list, this should work for almost any dual propane tank RV LP gas system.

The Marshall Excelsior RV Propane Regulator is another great replacement for most RVs and travel trailers. You may already have a Marshall regulator on your RV and this will be an exact replacement. The only downside is the lack of a rain cover, no included RV mounting bracket and you have either use your old pigtails or get new ones. Otherwise, it’s a great quality propane regulator and will keep the appliances in your RV running smoothly.

PROS

  • Propane Tank Gas Level Indicator Located on the Top
  • Adjustable
  • Automatic Changeover

Make sure you turn the lever on the top towards the opposite propane tank when you are going to remove the empty tank.

It’s already set at the standard 11” water column setting which is standard for all RVs and travel trailers so you shouldn’t need to do more than just connect pigtails and hook it up to your RV LP gas system.

It’s made for RV use and has the standard ¼” inlets and 3/8” NPT outlet.

The Fairview High Capacity RV Propane Regulator is perfect for the RV user that needs a lot of propane power all at once.

The empty tank indicator is located on the switch and will show red when the primary tank is empty, and it has switched over to the secondary tank.

The propane regulator is adjustable, but it comes pre-set from the factory for RV use and shouldn’t need any adjustment to read 11” on a water column. The inlets use the standard ¼” inverted flare and the outlet is the standard 3/8” NPT so it should be a match for any RV LP gas system.

The Camco Double Stage Dual RV Propane Regulator has a higher BTU rating than the other common standard RV propane regulators and is a good choice if you want to be able to run more propane appliances at the same time. The only downside is there’s no rain cover. It’s an easy fix if you have a waterproof cover for your propane tanks or they are in a compartment.

The empty primary tank indicator is on the side under the primary tank selection lever. It will show red when the tank is empty and be clear when the tank has propane in it.

The body of the RV propane regulator is made of Zinc and has durable brass fittings. It’s a very sturdy build but I would still recommend keeping it out of the rain as much as possible.

The RV propane regulator is adjustable, but it is recommended only for professional use. The inlets are the standard ¼” and the outlet is the standard 3/8” NPT so the Mr. Heater regulator should fit on any regular RV LP gas system.

My Recommendation for Best RV Propane Regulator

Flame King 2-Stage Auto RV Propane Regulator

Flame King (KT12ACR6) 2-Stage Auto Changeover LP Propane Gas Regulator With Two 12 Inch Pigtails For RVs, Vans, Trailers

Check Price at Amazon

The Flame King is made with RV and travel trailer users in mind. It’s super easy to install because it comes with pigtails and an RV bracket already connected. And the included rain cover is nice for those of us who have open propane tanks.

It’s nice and sturdy and has a good heavy feel to it. The automatic changeover works perfectly and it’s adjustable just in case you need that feature. The only thing I wish was different is the propane tank level indicator is on the side and you need to really look to see it. But that’s a small issue and the quality of the product is still excellent.

I would recommend this RV propane regulator to anyone, it’s one of the best you can buy for RV use.

  1. I know this a mostly RV website, but can this Flame King Auto 2 stage propane regulator have the same effect on a 18000 btu wall heater to be used in garage? Thanks

    Reply
    • Yes, even though they are mostly used on RVs propane regulators like the Flame Kings work great in garages and shops. The Flame Kings is rated for up to 190,000 BTU so a 18,000 BTU wall heater should be no problem for it.
