Buyer’s Guide to Buying the Best RV Propane Regulator

Picking out the best propane regulator isn’t too tricky, but does require a bit of know-how. The most important questions to answer are what type of regulator you need and what level of BTU flow you require.

There are certainly other considerations, but with those two questions answered you know you’ll get something that will work for you.


Propane regulators are very affordable parts for your RV. They start around $10 for basic/backup units and top out at about $50 for top of the line units with advanced features.

Capacity of the Regulator

The first thing you should look at when purchasing an RV propane regulator is the capacity of your RV. Any regulator you consider needs to be able to handle the full draw of your RV with space to spare.

This is measured in British Thermal Units (BTU) and should be listed on your RV owner’s manual. If you’ve modified the appliances within you’ll need to add up their total energy consumption to find out.

Protective Cover

All propane regulators need to be protected from the elements. Many models come with a protective cover right in the box, but some models do not.

We recommend you purchase one that includes a cover unless you already have one on your RV that is compatible.

Automatic Change Over

For RVers with a pair of propane tanks, an automatic changeover regulator can be a major value add. Once one tank is depleted the regulator automatically changes over to the other.

It adds a bit to the cost but saves you a ton of hassle and headache. Instead of having to hop out and turn a valve or manually move the regulator it does so automatically.

Construction and Material

With anything that touches the propane system of your RV we highly recommend you spend extra for better quality. You want a regulator made from highly corrosion-resistant materials in a design that’s built, or overbuilt, to withstand everyday use and a few bumps and bruises.

Ease of Installation

The most basic RV propane regulators require no more installation than screwing onto your tank and hooking them up to your RV connector hose. Once you get into auto changeover models the installation is a bit more involved.

They’ll often include manual switches to be mounted to the side of your RV and indicators that let you know how much propane is left in your tanks.

Different Types of RV Propane Regulators

There are three significant categories of RV propane regulators. These are first/single stage, two/dual-stage, and automatic dual tank regulators.

First or Single Stage Regulators – Single-stage regulators are the most basic and least expensive. They attach to a single propane tank securely and drop the initial pressure of the propane from 100+ psi down to a much safer operating pressure of 10-15 psi.

They attach to a single tank and require you to manually move the regulator when a tank is exhausted. Many also have a manual pressure knob that allows you to adjust the end pressure.

Two or Dual Stage Regulators – Dual-stage regulators have the same initial stage of single-stage regulators plus another one that further controls and manages the pressure. It drops it down to a consistent pressure of 1 psi.

That’s perfect for operating your RV’s appliances at peak efficiency.

The only downside to dual-stage regulators is that you still have to manually switch them from tank to tank when one is depleted.

Automatic Dual Tank Regulators – Automatic dual tank regulators attach to two propane tanks but only pull propane from one at a time. This gives you the efficiency of a dual-stage regulator plus the added convenience of access to two full tanks of propane.

Most also offer a tank empty/full indicator that lets you know when your tanks are empty.

What is an RV propane regulator?

An RV propane regulator is a device that controls the flow and pressure of propane gas from the propane tank to the appliances in your RV. It ensures a safe and consistent supply of propane for cooking, heating, and powering various onboard systems.

Why is it important to have a high-quality propane regulator for an RV?

A high-quality propane regulator is crucial for several reasons. It ensures that the propane pressure remains stable, preventing damage to appliances and maintaining their optimal performance. Additionally, a reliable regulator helps prevent propane leaks, which could lead to hazardous situations. Investing in a quality RV propane regulator is essential for safety and efficiency.

How often should I replace my RV propane regulator?

The lifespan of an RV propane regulator can vary depending on usage and environmental factors. As a general guideline, it is recommended to replace the regulator every 5 to 10 years. However, if you notice any signs of damage, irregular pressure, or propane leakage, it’s important to replace the regulator immediately, regardless of its age.

What types of RV propane regulators are available?

There are two main types of RV propane regulators: single-stage and two-stage regulators. Single-stage regulators deliver a constant propane pressure, while two-stage regulators have an additional stage that reduces the pressure even further to ensure a more consistent flow. Two-stage regulators are generally recommended for RVs as they provide better performance in varying conditions.

How do I choose the right RV propane regulator for my needs?

When selecting an RV propane regulator, consider factors such as your RV’s propane system setup, the number of appliances you intend to run simultaneously, and the climate conditions you’ll encounter. Look for regulators that have the appropriate capacity for your propane system and are designed to handle your expected propane demand. It’s also important to choose regulators from reputable brands known for their quality and reliability.

Can I install an RV propane regulator myself?

While it is possible to install an RV propane regulator yourself, it is recommended to seek professional assistance if you are not familiar with propane systems. Proper installation is crucial for safety and to ensure the regulator functions correctly. If you choose to install it yourself, carefully follow the manufacturer’s instructions and adhere to all relevant safety guidelines.

What are some important safety tips when using an RV propane regulator?

Here are a few safety tips to keep in mind:

  • Regularly inspect your propane regulator for signs of damage or wear.
  • Ensure proper ventilation in the propane compartment of your RV.
  • Use a propane gas detector to alert you in case of a leak.
  • Never attempt to repair a damaged regulator yourself. Replace it instead.
  • Always turn off the propane supply when the RV is not in use or during refueling.
  • Familiarize yourself with emergency procedures in case of a propane-related incident.
  • Remember, safety should be a top priority when dealing with propane systems in your RV.

Are all RV propane regulators compatible with all propane tanks?

Most RV propane regulators are designed to be compatible with standard propane tanks. However, it’s important to check the specific compatibility requirements mentioned by the regulator manufacturer. In some cases, you may need additional adapters or fittings to ensure a proper connection between the regulator and your propane tank.

Can I use a residential propane regulator in my RV?

It is not recommended to use a residential propane regulator in your RV. RV propane regulators are specifically designed to handle the unique demands and safety considerations of propane systems in recreational vehicles. Residential regulators may not provide the necessary pressure control and safety features required for an RV setup.

Remember to consult the manufacturer’s recommendations and seek professional advice if you have any doubts or questions regarding the compatibility of a specific regulator with your RV.

Final Thoughts

RV propane regulators aren’t really an exciting or ‘sexy’ product to buy, but they’re one of the most important components of an effectively operating RV.

So long as you know the basic specifications of your RV’s needs and some idea of what features you’re looking for it’s easy to pick out the best RV propane regulator for your needs.
