How to Straighten Pex Pipes

If you want to straighten your Pex pipes without damaging them, then this article is for you! We will walk through different methods of how to straighten Pex pipes so that you can get the job done quickly and efficiently. We’ll provide tips on how to make sure that no matter what kind of pipe you’re using, it won’t be damaged in the process. Get ready to learn about ways of straightening Pex pipes and start making those perfect bends!

Straightening a PEX pipe can be done by heating it with hot water, then holding one end of the pipe and applying pressure to the other end. Once heated, you should be able to straighten out most pipes within a few minutes. It is important to heat the entire circumference of the pipe evenly in order for it to properly take shape and stay straight; this may require using two or three hands at once. If needed, add more heat until you achieve desired results – however ensure that no part of your PEX has reached temperatures above 200°F (93°C).

Gather Supplies for Straightening Pex Pipe

One of the most important steps in straightening pex pipes is gathering all supplies needed for the task. Here’s a list of items you’ll need:

-Pex Pipe -Straightening Tool -Measuring Tape -Marker or Pencil -Wire Cutter (optional) -Gloves (for protection)

Having these supplies handy before starting any work on your pex pipe will help ensure that you have everything you need to get the job done effectively and efficiently.

Measure and Cut Pex to Length

Measuring and cutting PEX pipes to the desired length is the first step in straightening them. Start by measuring out the desired length of pipe with a tape measure and then adding an extra 4 inches, as this will allow room for any bends or kinks that may be present in the pipe. Once you have measured out your desired length, mark it on the pipe with a marker and cut it off using either a sharp utility knife or plastic tubing cutter. Be sure to wear protective gloves when handling PEX pipes as they can easily cause cuts due to their flexibility.

When cutting PEX piping, always use a blade designed specifically for plastic tubing such as those used for copper pipes since regular blades could result in jagged edges which would make fitting connections more difficult. Additionally, ensure that all cuts are made perpendicular (at 90 degrees) so that pieces fit together properly without causing leaks or blockages further down the line. Finally, if possible try to avoid making long straight cuts across multiple sections of pipe as this makes joining difficult later on – instead opt for short overlapping segments whenever possible.

Securely Fix the Pipe in Position

Securely fixing the pipe in position is one of the most critical steps when trying to straighten Pex pipes. The following list outlines some tips for ensuring a secure hold: 1. Use an appropriate clamp or fastener that fits your specific pipe size and type. 2. Tighten the clamp until you can no longer turn it with your hands, but don’t over-tighten it as this may damage the material or weaken its integrity. 3. Ensure that all clamps are firmly connected together so there is no slack between them, otherwise your pipe may move out of alignment during use and cause problems down the line later on. 4. Place supports at regular intervals along the whole length of the pipe to keep it rigid and prevent any bending or shifting under pressure from water flow etcetera

Heat the Fitting with a Torch

Straightening Pex pipes can be done in a variety of ways, but one of the most efficient methods is to use a torch. When heating the fitting with a torch, it’s important to ensure that the heat does not become too intense and cause damage to the pipe. To do this, use an adjustable flame so you have control over how hot it gets and make sure not to exceed temperatures exceeding 400°F (204°C). If you reach higher temperatures than this while using the torch, you risk melting or even cracking your Pex pipe.

In order to straighten your Pex pipe without damaging it while using a torch, position your flame close enough so that only half of its surface area is affected by direct heat at any given time. This will help evenly disperse heat along both sides of the fitting as opposed to concentrating all of it on one side which could cause warping or discoloration. In addition, keep turning and rotating the Pex pipe in order for full coverage when applying heat from different angles until desired results are obtained.

Finally, safety should always be considered when working with torches especially since propane tanks used for heating up fittings can become explosive if mishandled. Make sure there is no combustible material near where you’re working as even sparks from opening lighters or matches could result in serious injury or death if proper precautions aren’t taken beforehand.

Push on Heated Ends of Pipe Simultaneously

Straightening pex pipes–also known as cross-linked polyethylene pipes–requires extreme caution and precision. The most common method of straightening these types of pipes is to simultaneously push on the heated ends. This technique requires two people working in unison, which can be difficult if you’re tackling a large pipe. The biggest advantage of this approach is that it minimizes the risk of kinking or breaking, since by pushing together from both sides you’re less likely to apply too much force in one direction causing unequal pressure along the length of the pipe.

Begin by heating up each end separately using either hot water or a heat gun until they become pliable. You should take extra care here as excessive heat can cause permanent damage to your pipe and any surrounding material, so make sure not to overheat them! As soon as both ends have softened sufficiently, have one person hold onto each end while applying gentle pressure away from each other towards their respective centres; keep an eye on your progress so that you don’t overdo it and avoid sudden movements that could break or bend the plastic further out of shape than desired.

Once the desired level has been achieved then carefully remove each side’s grip before allowing them time to cool down and harden into place; do not attempt to move any part while they are still warm otherwise you may find yourself back at square one! With patience and practice anyone should be able to master this technique, enabling quick repairs without sacrificing quality results – just remember: always put safety first when dealing with hot objects like piping systems!

Check that the Bend is Straightened

Straightening a PEX pipe is an important step in any plumbing job. To ensure you get the best results, follow this checklist to make sure your bend is straightened properly:

1. Measure the length of the pipe and mark out where you want the new angle to be. 2. Use a heat gun to slowly heat up the marked area until it’s hot enough that you can push or pull it into shape with your hands. 3. Once you have achieved your desired angle, use pliers or clamps to hold it in place while cooling off with cold water so that it sets correctly. 4. Finally, check that the bend is straightened by comparing against your original measurements – if there are still any bends remaining then repeat steps 2-3 until perfect!

Finish Up Connections with Clamp or Glue

In order to complete the straightening process of PEX pipes, you must either use a clamp or glue to finish up the connections. Here are some steps to get it done:

1. Securely position and align each section of PEX pipe as needed for your project. 2. Wrap any exposed threads on fittings with thread-seal tape for extra protection against leaks. 3. Connect joints together by tightening clamps around them or applying glue according to manufacturer’s instructions once all pieces have been aligned correctly. 4. Allow time for the glue or clamps to set properly so that no water leakage occurs from loose connections later down the line when in use!


In conclusion, learning how to straighten PEX pipes is an invaluable skill for any plumbing professional or DIY enthusiast. Despite the challenging nature of this task, it can be accomplished with patience and practice. With the right equipment and knowledge of proper techniques, anyone can successfully straighten a PEX pipe without damaging it in the process. It’s important to use caution when dealing with these delicate materials and always wear appropriate safety gear such as gloves and eye protection. Doing so will ensure that you are able to complete your project safely and effectively, ultimately creating a superior finished product for yourself or your customer.
