How to Bend PVC Conduit with a Heat Gun | Step-by-Step Guide

PVC conduit is a great way to protect your cables, but it can be difficult to bend it into the right shape. It’s not easy to bend PVC conduit without damaging it. If you try to do it by hand, you might end up with kinks or cracks in the plastic.

The best way to bend PVC conduit is by heating. By heating the plastic slowly and evenly, you can avoid any damage and get the perfect curve every time.

Do you need to bend PVC conduit but don’t have a bending brake? In this blog post, we will teach you how to do it. It is actually very easy and only takes a few minutes. Follow simple steps and you will be able to create curved or angled conduit bends in no time.

Can We Bend PVC Conduit with a Heat Gun?

PVC conduit is made of a type of plastic that becomes softer and more pliable when heated. This makes it possible to bend the conduit to fit around obstacles or to create curves.

We often get asked, can you bend PVC conduit with a heat gun? The answer is yes, However, there are a few things to keep in mind when using this method.

Cautions while bending PVC Conduit:

  • First, you’ll need a heat gun that gets hot enough to soften the PVC.
  • You’ll need to experiment with the distance of the heat gun from the conduit.
  • You should only bend the conduit a little bit at a time. Bending too much at once can cause the conduit to collapse or crack.
  • When bending PVC conduit, make sure to have a fire extinguisher handy, just in case.
  • When using a heat gun to bend PVC conduit, it’s important to use low heat. Too much heat can damage the conduit or make it difficult to control the shape.
  • It’s also important to work slowly and carefully. Heating and bending the conduit in short sections will give you more control over the final shape.
  • Finally, be sure to use gloves when handling the heated conduit. This will protect your hands from any potential burns.

If you follow these tips, you should be able to successfully bend PVC conduit with a heat gun.

How to Bend PVC Conduit with a Heat Gun?

The answer is quite simple, really. All you need is a heat gun and some patience. PVC conduit is notoriously difficult to bend, but with a little bit of heat, it becomes much more malleable. Here’s how to do it:

  1. First, you’ll need to mark the spot on the PVC conduit where you want it to bend. This is important because it will help you keep a consistent angle while you’re heating up the plastic.
  2. Once you’ve marked the spot, position the heat gun about six inches away from the PVC and turn it on to high heat.
  3. Slowly move the heat gun back and forth over the area you want to bend, making sure to keep the gun moving so that you don’t overheat any one spot.
  4. After a minute or so of heating, you should start to see the PVC conduit becoming softer and more pliable.
  5. Once it’s reached this point, you can start to gently bend it to the angle you desire. Just be careful not to overheat, as the heat can cause the PVC to become brittle and break if you’re not careful.
  6. Once you’ve reached the desired angle, turn off the heat gun and allow the PVC conduit to cool and harden in that position.
  7. And that’s all there is to it.

With a little bit of heat, you can easily bend PVC conduit to the shape you need.

Pros of using a heat gun for bending PVC Conduit:

  • You can control the amount of heat being used.
  • Can be done without any special equipment.
  • You can achieve the precise angle that you want.
  • You can get a tight bend without kinking the pipe.
  • Heating the pipe evenly will prevent it from sagging or breaking in the middle of the bend.
  • Bending with a heat gun is much faster than using a manual bender.

Cons of using a heat gun for bending PVC Conduit:

  • PVC can emit toxic fumes when heated, so good ventilation is a must.
  • Too much heat can cause the PVC to become brittle and break.
  • If not done carefully, the heat gun can easily damage the conduit.


Q: What are the minimum and maximum radius for bending PVC conduit?

A: The minimum bend radius for PVC conduit is four times the diameter of the conduit. The maximum safe bend radius is eight times the diameter of the conduit.

Q: How do you know when you have reached the maximum safe bend radius?

A: If the conduit starts to kink or deform in any way, you have reached the maximum safe bend radius and should stop bending.

Q: How do I know if I am using too much heat when bending PVC conduit with a heat gun?

A: If the PVC conduit starts to emit fumes, you are using too much heat. Turn the heat gun off and allow the conduit to cool before continuing.

Q: What is the difference between PVC and PVC-coated conduit?

A: PVC-coated conduit has a layer of PVC material surrounding it. This provides additional protection against corrosion and abrasion.

Q: Can I use a regular household hair dryer to bend PVC conduit?

A: No, you should not use a regular household hair dryer to bend PVC conduit. The heat produced by a hair dryer is not intense enough to properly bend PVC conduit.

Q: Can I use PVC conduit outdoors?

A: Yes, PVC conduit can be used outdoors. However, it is important to note that the conduit should be rated for outdoor use. Additionally, you will need to use weather-resistant fittings and accessories when installing PVC conduits outdoors.

Q: What are the benefits of using PVC conduit?

A: PVC conduit is a popular choice for electrical projects because it is durable, easy to work with, and cost-effective. Additionally, PVC conduit offers excellent protection against corrosion and moisture damage.

Q: What is the difference between PVC and PVC-coated conduit?

A: PVC, or polyvinyl chloride, is a type of plastic. PVC-coated conduit is made of metal, with a layer of PVC over it to protect the metal from corrosion.
