Can Flexible Conduit Be Used Outdoors? (Explained)

The flexible conduit is aluminum-made high-quality cables that are not suited for watery places. All the damp or wet places are unsafe to use the flexible conduit. If you have these places, you need to use a rigid conduit that can withstand the heat & water.

If you have a flexible conduit, you should know where you can use it and where you can’t. They will give you the best experience in the perfect place; other than that, the flexible conduit has other benefits that make it an excellent cable for different uses.

Can flexible conduit be used outdoors?

The flexible conduit cannot be used outdoors. It is unsafe because of the build material and flexible structure; it can be used indoors. You can use it for electricity or the gas line. It will be a perfect match for indoor or under-constructed buildings where you can install it properly.

Since the aluminum-made flexible conduit cannot be suited for damp places and is not safe for outside activities, you cannot use it outdoors.

Moreover, the flexible conduit is not the best suited for the rigid environment. If you have the best-suited metal cables, you can safely run them for the gas line.

Let’s see where you can use the flexible metal conduit and other versions.  

Flexible metal conduit:

You cannot use the flexible metal conduit outside. It has a rigid and flexible build structure that makes it excellent for indoor use.

If you need to use a strong cable outside the house, you must focus on other cables mainly made for outdoor uses.

But the flexible metal conduit will fail miserably to withstand the heat and water. Also, it is not suited for the extra pressure to be a durable and long-lasting cable line for the future.

Whenever you have the option to use the flexible metal conduit, you must use it indoors.

Flexible aluminum conduit:

You can only use the adjustable stainless steel conduit outside if it meets the codes and can withstand harsh conditions.

But it is safe not to use the flexible aluminum conduit outdoors; it’s an ideal metal cable for indoor electricity and other uses.

If you badly need to use the flexible aluminum conduit outside, you should look at the structure and find out the best place for using it. Don’t bury these cables or use them in harsh conditions; they might damage the structure.

Flexible PVC conduit:

Finally, a perfectly matched cable is suited for use outdoors. Since it is rigid and will be an excellent fit, you can use the flexible PVC conduit for all outdoor/outside use.

It can withstand water, mud, and harsh conditions, which is the main concern of using flexible conduits.

Therefore, you can expect it to become your best choice for the outside activities and uses. You can also bury them and expect them to work for a long time without being broken or damaged.

Is flexible conduit waterproof?

Not all flexible conduits are waterproof. Only the metal and specially designed conduits are waterproof. They lack waterproof jackets, which cannot resist moisture and water; therefore, you cannot use them in damp places.

Moreover, the flexible conduit can be bent, and you can give it the desired structure to fit the electric lines and gas lines. Also, you can use them indoors from a very subtle point. You don’t need to think about the durability and the quality.

Since they are not waterproof, you cannot use them in harsh conditions like damp or watery places. If you have any constraints, you need to be careful about choosing the suitable conduit for the right place.

Can flexible conduit be exposed outdoors?

The flexible conduit cannot be exposed outdoors because they are not waterproof and can’t bear harsh weather conditions. If you want to use the flexible conduit outdoors, you need to use the PVC conduits.

They are safe and will go for a long time. Especially the flexible conduit will make your indoor construction easier and safer. You can replace all your existing electric lines using the flexible conduit. But to use it outdoors, you can’t do that.

If you want to expose the flexible conduit, you need to use the PVC conduit that can bear the heat and resist the water. The PVC conduit is waterproof; it can withstand both heat & water. Therefore, you can use it in harsh weather ideally.

3 reasons why you cannot use flexible conduit outdoors

Flexible conduit cannot be used outdoors because it is not designed for outdoor use that interrupts wet areas. Besides, the flexible conduit is fairly limited in its value, yet there are several applications where it is a reasonable choice.

For your help, we have shared some reasons that perhaps make you confident to make the decision why you do not use it outdoors.

Production limitations:

Flexible Conduit has a helical physical issue, customarily produced using aluminum. Using it outside can cause various problems as the environment changes because of its durability.

Just as it can leak in the wet and cause an accident, it can become rough and burst in the summer, which can make a chance to get in trouble.

Technical efficacy:

As it is by and large utilized for conveying water and other liquid or for completing specific different purposes, for example, safeguarding electric links, it should be viable both physically and technically.

But apparently, the existing components in the market are deteriorated to commit to their minimum need.

Lack of compatibility:

The flexible conduit is not expected for a broadly applicable raceway for a significant distance. Besides, adapting to different convoluted structures is difficult with more modest widths.

These are meager divider roundabout cross-segments that are stirred outside for consumption assurance so that they can not last after a year. For many reasons, it is perceived that this flexible conduit is not scrutinized for outdoor use.

Can flexible conduit be used underground outdoors?

A flexible conduit can be used underground outdoors because it fits this environment properly.

Contingent upon their adaptability and flexible mechanical conduits, courses can be introduced underground to safeguard utilities against harm, altering, and enduring.

Flexible conduits come in incredibly valuable and proposition a large group of security highlights, including erosion, fire, and water obstruction. Flexible conduits covered underground make a far more secure and neater other option.

They are frequently utilized for longer runs as they are speedier to introduce than their unbending partners. When lines and links are covered, they ought to be laid in a conduit.

The curl will contain a draw cord that empowers lines or connections to get through whenever introduced. Loops can then be consolidated utilizing free couplers.

Above all, you can relate it to your needs and why it is generally used underground outdoors that could be clear simultaneously.

Where can flexible conduits be used?

The flexible conduits can be used indoors. You can also use it for gasoline. It has a sturdy build that is flexible; therefore, you can bend it and give it the desired structure for getting the best structure to get the utmost structure for the electric system.

You can also use the flexible metal conduits for the gas line; it won’t get rusted, damaged, or leaked.

So, it won’t damage your gas line and will pass the gas securely from here to there. Additionally, the flexible conduits are best suited for internal gasoline.

You can use it for all the wiring systems. And it would be best if you installed the flexible conduits when you start the construction work.

It will be better to give your wiring system the best flexible conduits. Moreover, the cable must meet the requirements to become the best-suited cable for the wiring.

What type of conduit should be used outdoors?

You cannot use all types of conduits outdoors. But you need to avoid the flexible conduits in most cases; they are not strong enough to use outdoors. You must be sure that the conduits can bear the extra pressure and heat.

You may use the flexible PVC conduit outdoors. You cannot use the aluminum conduit for outdoor uses because of the structure.

You must be careful about the flexibility and deformation of the metal-made conduit for getting the damaged conduits which might be dangerous.

So, here is the list of perfect conduits that you can use outdoors. They are all suited for outdoor activities and wiring systems. You can use these conduits for all outdoor uses.

  • Flexible PVC Conduit
  • Non Metallic Conduits
  • EMT Conduit

Final Thoughts

Although the flexible conduits are not suited for the outdoors, you can use the flexible PVC conduits for outdoor uses. The build quality and the structure is not suited for outdoor activities. They can easily be deformed and will damage the entire outdoor cable. So, you should avoid it outdoors.
