What Does a Propane Regulator Do?

Propane regulators are an integral component of any propane gas system. The objective of a regulator is to control the gas flow and decrease the pressure from the LP gas tank to the appliance in the system. These act as a safety barrier between the tank's high pressure and the appliance at the other end by ensuring a steady flow of gas at a constant pressure as required by the appliance in question.

In short, an RV propane regulator acts as a ‘bottleneck’ to the gas flowing through the system and makes sure it flows at a usable and safe pressure.

How to Tell if a Propane Regulator is Bad 

There are a few tell-tale signs showing that a propane regulator is bad and remains no longer usable:

  • A car's tailpipe emitting black smoke is a sure short warning that the fuel pressure regulator is faulty.
  • A tailpipe leaking gasoline can be due to an overfilled gas tank too, but most often, it means that the gas regulator is leaky.
  • An engine stalling when the gas pedal is pushed means that the gas regulator is not doing its job.
  • The smell of fuel or a backfiring engine upon acceleration indicates gas build-up due to a dysfunctional gas regulator.

What Kind of Propane Regulator Do I Need?

To begin with, your propane regulator needs to be compatible with your propane tank and your fuel hose. Larger RV appliances typically need high-pressure propane regulators because they demand more pressure than can be delivered by a low-pressure regulator. You should shortlist the pressure rating of your propane regulator based on the number of BTU/hr required by your RV, and pick the closest match.

Since the demands of your RV won't change over time, you can go with a pre-set propane regulator. However, getting an adjustable regulator will not make any difference either. You can simply adjust the output pressure using the control built into the propane regulator.

What Makes a Great Propane Regulator?

There are some key features to look out into when purchasing a propane regulator:


One crucial aspect of any propane regulator system is its durability. The good ones of the lot - the ones that you can expect to last 10+ years - employ heavy-duty construction and say so on the package. Prefer going for a stainless steel part with powder coating, because those are extra resistant to corrosion.


The next most important feature of any fuel system is its capacity. Capacity refers to the amount of gas that the regulator will allow to pass through. The higher the specific BTU capacity of a propane regulator, the higher is the price tag. You need to find a balance between the capacity and the price because after all, getting a regulator with capacity higher than that of your fuel tank is just pointless.

Automatic Change Over

If your RV has two propane tanks, and you are often away from fuel stations, you can benefit from getting them both filled and using an automatic change over propane regulator to switch between the two tanks as the first one gets consumed. Good regulators usually have a color indicator that switches from green to red when the first tank is depleted, and it's time to switch to the second one.

Protective Cover

This is a very important element because it keeps your purchase safe from water and moisture, thereby preventing corrosion of the metal. You should get a regulator which comes with an original cover, because separately purchasing a cover is costly, and it is also difficult to find the right fit.

Types of RV Propane Regulators

Propane regulators come in various different kinds, and it is imperative that you select the one most compatible with your appliance and your requirements. Listed below are the types you would most frequently come across:

First Stage Regulators

Also known as single-stage regulators or low BTU regulators, these are best used with small cylinders in appliances akin to outdoor grills and camping stoves. First installed at the fuel tank, they are then connected to the service valve via a hose. These typically have high BTU capacities, and their main purpose is to transfer propane at a stable pressure to another second stage regulator with a smaller BTU capacity. Understandably, it is integral that the two regulators are compatible. 

Second Stage Regulators

Found downstream from a first stage regulator, these regulators serve to lower the tank pressure and thereby guarantee safety. It reduces the outlet pressure by cutting the propane flow before it reaches the appliance, and for safety reasons are typically connected via a stainless-steel hose instead of a standard rubber hose.

Integral Twin Stage Regulators

This is the most commonly occurring type of regulator and can be used with various appliances. However, if there is a large distance between your appliance and your fuel tank, it is best to avoid this system, because it will lower the pressure far too much to allow the appliance to operate.


Now that you know what RV propane regulators do, what features can make or break an RV propane regulator, and have also gone over our roundup of the top RV Propane Regulators, we hope that you are ready to dive into your purchase. Make sure you match your needs with the features offered by the unit to make the right purchase. 

People Also Ask

For any confusion or queries that you still may have regarding RV propane regulators, we have shortlisted the top questions that consumers most frequently ask. We have answered them with all the details that you need to know in order to make an informed purchase decision.

How to Reset a Propane Regulator

Begin resetting your RV propane regulator by first turning off all the RV appliances, turning off the fuel tank, and then disconnecting the hose from the tank. Now give the regulator a little while to reset itself, and then very slowly, turn the propane tank valve back on until the lines are adequately pressurized. 

How to Thaw a Propane Regulator

The process is just as simple as you would thaw anything else that is frozen. Detach the tank from the hose, and take your regulator off the tank. Bring it inside or leave it in a warmer place overnight, and it will thaw out on its own. Reattach it the next morning and should work fine.

How to Adjust a Propane Regulator

If you have a pre-set propane regulator, it cannot simply just be adjusted. What you can, however, do is, increase the gas volume by connecting another low-pressure regulator and compatible hose. On an adjustable regulator, making adjustments is fairly simple. Pull off the regulator lid, and turn the adjusting screw underneath according to the direction of adjustment marked on the regulator. 

How Do You Keep a Propane Regulator from Freezing?

Follow a regulator-friendly routine to keep your propane regulator from freezing. Keep the regulator slightly elevated against a stable surface, always be sure to use a regulator cover. Make the regulator vent hole point downwards, so all the moisture is drained out. 

What is a Two-Stage Regulator for Propane?

The two-stage propane regulator system is simply the combination of the first stage regulator and the second stage regulator. The first stage regulator serves to manage the pressure entering into the second stage regulator, and the second stage regulator looks over the pressure going into the RV appliance. 

When to Use a Two-Stage Propane Regulator

Two-stage propane regulators offer lower variations in the pressure as compared to single-stage versions. They also come with a heavier price tag. You should buy them only if your appliance is sensitive to over and under firing.

How Long Will RV Furnace Run on Propane?

A typical RV furnace will run on one gallon of propane for a 24-hour long period, given that the furnace kicks on for two minutes approximately every 15 minutes. A standard 20-gallon propane tank holds 4.5 gallons of propane, so it keeps the furnace heated for more or less 4.5 days.
