A Comprehensive Buyer’s Guide

Propane regulators for RVs are what help control and distribute a very flammable substance, so you must get the most amount of control and durability out of your regulator.

But there are numerous other features that you’ll want from a propane regulator, such as good build quality and capacity, as well as how much it costs and how easy it is to install.

Here are a few things that you’ll need to consider before purchasing your next propane regulator:

How Much Will It Cost?

Propane regulators largely don’t cost you a great deal of money, as they are only small and simply restrict the flow of gas into your RV.

However, several manufacturers have developed a few propane restrictors that have extra functions such as temperature and pressure readouts.

If you want a higher output of BTUs, then you’ll probably be looking to spend a few dollars more on a heavy-duty model of regulator.

Getting a warranty for your regulator is also crucial in case it malfunctions, as these delicate devices often can. Again, you’ll be looking to pay a little bit extra for a decent warranty that gives you at least a year’s coverage.

What Is Your Regulator Made From?

This might be the most crucial feature you’ll want from your regulator: that it can withstand high pressures from inside and out for a long period.

Most of these models won’t last you forever, due to the high forces they control, the chances are they will eventually malfunction.

The most important thing you can control is when it malfunctions. Buying a decent regulator that lasts up to 10 years can save you time and money in the long run, as well as ensuring your safety.

Regulators come in mainly a few metal materials such as aluminum, brass, raw zinc or stainless steel. Discover all the benefits that these materials have to offer, as well as how you want the heat to be distributed through your appliances before purchasing.

Remember: regulators are also very susceptible to corrosion and rust, so you might want to invest in a plastic coat to protect your precious regulator from the elements.

How Easy Is It To Install?

Ideally, your regulator won’t have a very difficult installation process, as they are designed with the assumption that most people won’t have the technical expertise to install them.

You can fit these regulators simply and without the need of a professional.

Some of these regulators, unfortunately, don’t come with mounting hardware, which can make the process of installation more trouble than it’s worth.

A good regulator brand should ideally supply you with all the tools you need for installation.

You’ll also want clear instructions on how to install this device, which is especially important to avoid improper installation and further leakage.

What Is The Capacity Of Your Regulator?

Each propane regulator has a different capacity, usually referred to as its BTU. This is a measurement of how much gas is allowed to flow into your RV from the tanks.

The higher the BTU, then the more gas – and more power – your tank will be able to produce.

When it comes to power, you’ll need anything that produces over 50,000 BTUs to meet all your expectations, although obviously, you’ll have to factor in how many onboard appliances you’ll need to supply too.

Frequently Asked Questions

How Can You Adjust A Propane Regulator?

Adjusting an RV propane regulator can be a potentially dangerous business, especially considering how much lethal gas is inside one tank.

How Can You Adjust A Propane Regulator

Ideally, this task should be left up to a professional, as you want to minimize the risk of hurting yourself and others as much as possible.

When it comes to installing your propane regulator, you should be able to easily do this yourself. Read the instructions carefully though, as an improper installation could lead to fatal consequences for yourself and those around you.

How Can You Install A Propane Tank To An RV?

It is understandable if you are feeling concerned about installing your RVs propane tank, especially if you’re meddling with large quantities of highly explosive gasses!

But, we can help make this process a lot simpler. Follow these easy steps and you should be able to install your tank in no time at all!

  • Examine the exterior of your RV and see if the propane is a horizontal or vertical attachment. Horizontal propane is stored in ASME tanks, whereas vertical connections use DOT tanks.
  • Purchase an appropriate tank from the local store, gas station or auto shop.
  • Place the tank in the cradle, which is the metal compartment for attaching the tank to the RV. Fasten the hose and propane connector to the propane tank’s nozzle.
  • Latch or tie straps into place to provide the tank with extra support. You’ll need to ensure the tank is as stable as possible.
  • Locate the valve on the tank and turn it gently to the right to open up the tank and start the flow of propane. If you hear a hissing sound then this is a sign that you have incorrectly fitted the tank and you should shut off the supply and try to correct the issue.
