Selection Criteria

Propane Hose Extension

Besides furnaces, propane extension hoses can be used with grills, generators, and various other propane appliances. In addition, they’re frequently utilized by RV, mobile homes, and house owners to connect propane tanks to different types of appliances.

Despite a wide range of available options, finding an extension hose that is compatible with your appliance can still be difficult. I’ve set a strict set of parameters to select the models that can meet the needs of a broad spectrum of users.

Let’s take a closer look at the criteria I used to pick the propane hose extensions I featured in this article.

Hose Length

A propane tank needs to be at a safe distance from the appliance it is powering. The length of the models I included in this article spans from 4ft to 12ft, so you can pick the option that best serves your needs.

Safety Features

Pressure gauges, control valves, or leak detectors are some of the most important safety features a propane hose extension should have. I used this parameter to pinpoint the models equipped with features that ensure a safe connection between a propane tank and an appliance.

Build Quality

The durability of these accessories depends on their build quality. So, I only considered models with corrosion-resistant fittings and sturdy, flexible hoses.

What’s a Propane Extension Hose?

Propane Extension Hose

Propane fuel tanks usually have a hose that is just several feet long, and in most cases, it cannot reach the appliance it’s supposed to connect to its fuel source. Moreover, most propane appliances don’t have built-in hoses as this accessory is usually sold separately.

A propane extension hose allows you to extend the length of the tank’s original hose so that it can reach the fuel supply. Moving a propane tank closer to a grill or a furnace is often impossible and dangerous, so an extension hose lets you use these appliances without jeopardizing your safety.

Increasing the length of a propane hose won’t affect the gas pressure because the pressure equalizes in the line, and it remains at the same level even if you extend the hose length over 50 feet.

In addition, most propane extension hoses come with gas pressure gauges that enable you to monitor the current gas pressure. Check out our guide to the best propane conversion kits if you want to power a natural gas furnace with propane.

The Minimum Distance Between a Propane Tank and an Appliance

Keeping a propane tank of any size in a garage or basement is both dangerous and prohibited by the law. Ensuring that the tank’s valve is tightly closed isn’t always possible, so even the slightest gas leak can lead to explosion and fire.

Ideally, your propane tank should be stored at least ten feet away from your home in a well-ventilated area that isn’t exposed to direct sunlight. Keep in mind that a tank that can hold between 250 and 2,000 gallons of propane needs to be at least 25-feet away from the nearest building.

The same rules apply for tanks that are installed above and below ground, except for aboveground tanks with storage capacities below 125 gallons. A tank that can hold 100 gallons of propane or less needs to be five feet away from your home.

In case two propane tanks of any size are stored within 3-feet of each other, the mandatory distance from the nearest building increases to 25 feet. Measuring the distance between the propane tank and the furnace will enable you to know how long the extension hose should be.

Features of Propane Extension Hoses

Propane Extension Hoses

The features of these accessories vary from model to model. Their hoses are usually made of rubber, but braided stainless steel or polyethylene are also among the materials used to produce hoses. Fittings are almost always made of brass or similar corrosion-resistant materials.

Control valves, gas pressure gauges, and leak detectors are not standard features on all propane extension hoses. Getting a model equipped with these features will make it easier to monitor the gas pressure or cut off the propane supply to the device.

Accessories like thread sealant tape or thread sealant glue are sometimes sold with extension hoses because they prevent gas leaks. Applying a thread sealant tape or glue will make the connections between hoses, tanks, and appliances stronger and safer.

Types of Propane Extension Hose Fittings

The propane extension hose you choose needs to be compatible with the fittings on the hose you’d like to extend and fittings on the appliance. You should also make sure that you can connect a propane extension hose to the propane tank regulator.

The most common types of propane extension hose fittings are:

POL Fittings

You’ll likely encounter this type of fitting on large tanks. They’re easily recognizable because their valves thread on the inside of the connector. A wrench is required to tighten the fitting properly.


These fittings are typically used to connect two pipes because they create a strong thread seal. You can install propane hose fittings with hose fittings without using a tool.

QCC1/Type 1 Fittings

The nut-and-nipple assembly makes QCC1 fittings easily recognizable. They’re not prone to leaks because they create a tight seal.

Flare Fitting

These fittings utilize a nut to produce a pressure-tight connection.

The Most Important Factors to Consider While Choosing a Propane Extension Hose

Propane Hose Extension

The process of selecting a propane extension hose isn’t overly complicated. Even so, you can easily end up with a hose that isn’t compatible with your heating system if you ignore the model’s properties.

Most importantly, the hose you choose must be compatible with the hose you want to extend and the appliance you’re connecting to a propane tank. I’ve shortlisted some of the most important factors that can make the search for a propane extension hose easier, so let’s take a look at them.

Propane Tank Size

Most households that utilize gas furnaces for heating have 500-gallon propane tanks that need to be at least 25 feet away from the nearest building, while a tank with 100-gallon capacity can be stored 5-feet away from your home.

Hence, the length of the extension hose needs to be suitable for the size of the propane tank you have.

Hose Length

You must measure the distance between the propane tank and the appliance to know how long the extension hose should be. Although a propane tank needs to be at least 10-feet away from the house, the hose with the same length might not be long enough to connect the tank to the appliance.

You can combine several 12-feet hoses if your propane tank is more than 25-feet away from a furnace or get a 5-feet hose if you’re working with a 25-gallon or 50-gallon tank.

Fitting and Hose Material

The extension hose is often exposed to high temperatures and easily accessible to pets and other animals that go through your courtyard who might attempt to bite it. That’s why you should choose a hose made of a sturdy and flexible material that can’t get damaged easily.

You should also pay attention to the fitting size. Even if you get a hose that has the same fitting type as the furnace, hose, or fuel tank regulator, you may not be able to use it if its fittings are too big or too small. For example, most propane hose extensions have 3/8, ¾, or 7/8-inch fittings.

Safety Features

Opting for a propane hose extension that can detect a gas leak will improve your safety. Some models can have gas pressure gauges or control valves that allow you to have complete control over the flow of propane.

It is advisable to use a thread sealant glue or tape to ensure the gas won’t leak at the connections between hoses.

Price and Durability

These accessories aren’t expensive as they usually cost less than $40. However, their price depends on the hose’s length, so you’re going to have to spend a bit more if you want to get a 20-foot hose extension.

These hoses don’t wear out quickly, and in most cases, you can use them for more than ten years. Unfortunately, most manufacturers don’t issue warranties for their propane hose extension models.

The Advantages of Propane Hose Extensions

Propane Hose Extensions

Easy Assembly

Attaching a propane hose extension to a gas tank, another hose, or a propane appliance is a straightforward process. You just have to make sure all threads are tightly sealed before you start using an appliance.

More Freedom in Positioning Appliances

A propane hose extension allows you to use an appliance without having to worry if it is too close to its fuel supply. These accessories also make it easier to comply with the tank placement laws as they allow you to connect an appliance to a tank regardless of how far apart they are from each other.

Affordable Price

You can get a 12-foot propane hose extension for less than $40. So, in case you’re using a 500-gallon propane tank, you’ll have to spend around $80 to connect a furnace to its fuel supply.

The Disadvantages of Propane Hose Extensions

Dirt Accumulation Can Cause the Propane Hose Extension to Malfunction

A propane hose extension can get clogged over time because the dirt accumulates in its pipe. You will have to replace the hose if this happens since unclogging the pipe is often impossible.

Some Models Lack Safety Features

Gas pressure gauges or leak detectors are not standard features on all propane hose extensions. So, monitoring the gas pressure or determining if the gas is leaking can be difficult if you opt for a model that doesn’t have these features.
