Supporting the PEX During Cutting
Supporting the PEX pipe during cutting is crucial to prevent kinking or bending, which can affect the water flow and compromise the integrity of the pipe. Here are detailed guidelines for supporting the PEX during cutting:
Step 1: Use a Stable Surface
Place the PEX pipe on a flat, stable surface that will not move or flex during cutting. This could be a sturdy table or workbench, ensuring that the pipe is fully supported along its length.
Step 2: Use a Sharp Cutter
A sharp cutter is essential for clean cuts that minimize the risk of kinking. Use a specialized PEX cutter or a sharp utility knife. A dull cutter can crush or tear the pipe, leading to weaker connections and potential leaks.
Step 3: Support the Pipe with a Mandrel or Spring
To prevent the PEX from collapsing or kinking during cutting, insert a mandrel or spring into the pipe. A mandrel is a rigid rod or tube that fills the pipe’s inner diameter, while a spring provides support without completely filling the pipe. This support mechanism ensures that the pipe retains its shape and integrity during the cutting process.
| Support Method | Pros | Cons |
|---|---|---|
| Mandrel | Provides maximum support, preventing kinking. | Requires specific mandrel sizes for different pipe diameters. |
| Spring | Flexible and can accommodate various pipe diameters. | May not provide as much support as a mandrel, especially for larger pipes. |
Best Way To Cut PEX
PEX (cross-linked polyethylene) is a flexible, durable, and corrosion-resistant type of plastic pipe that is increasingly becoming the preferred choice for plumbing applications. Unlike traditional copper or galvanized steel pipes, PEX pipes are easy to cut, making it a popular option for DIY plumbing projects.
There are several methods that can be used to cut PEX pipes, each with its own advantages and disadvantages. The best way to cut PEX pipes will depend on the specific application and the tools that are available.
Here are the two most common methods for cutting PEX pipe:
- Using a PEX cutter: A PEX cutter is a specialized tool that is designed specifically for cutting PEX pipes. PEX cutters typically have a sharp blade that is angled to create a clean and square cut. They are easy to use and can be purchased at most hardware stores.
- Using a utility knife: A utility knife can also be used to cut PEX pipes, but it is important to use a sharp blade and to score the pipe several times before cutting all the way through. Utility knives are not as precise as PEX cutters, but they can be used in a pinch.
Once the PEX pipe has been cut, it is important to deburr the edges of the pipe to remove any sharp edges. This can be done using a utility knife or a deburring tool.

Can I use a hacksaw to cut PEX pipe?
Yes, you can use a hacksaw to cut PEX pipe, but it is not the best method. Hacksaws can leave a rough edge on the pipe, which can lead to leaks. It is better to use a PEX cutter or a utility knife.
What is the best way to cut PEX pipe underground?
The best way to cut PEX pipe underground is to use a PEX cutter. PEX cutters are designed to cut PEX pipes cleanly and squarely, even in tight spaces. If you are cutting PEX pipe that is buried deep underground, you may need to use a longer PEX cutter or a utility knife with a long blade.
How do I cut PEX pipe without a cutter?
If you do not have a PEX cutter, you can use a utility knife to cut PEX pipe. However, it is important to use a sharp blade and to score the pipe several times before cutting all the way through. Utility knives are not as precise as PEX cutters, but they can be used in a pinch.
