How To Cut PEX Tubing: A Complete Guide
Hey guys! Are you diving into a plumbing project that involves PEX tubing? Well, you’ve come to the right place! PEX (cross-linked polyethylene) tubing is a fantastic material for plumbing due to its flexibility, durability, and ease of installation. But before you start connecting those pipes, you need to know how to cut them properly. Cutting PEX tubing might seem straightforward, but doing it right ensures a leak-free and long-lasting plumbing system. In this guide, we’ll walk you through everything you need to know about cutting PEX tubing like a pro. So, grab your tools, and let’s get started!
Why Proper Cutting Matters
Before we jump into the how-to, let’s talk about why proper cutting is so crucial. Imagine spending hours installing a plumbing system only to find out you have a leak because of a wonky cut. Not fun, right? A clean, square cut is essential for creating a secure connection with PEX fittings, whether you’re using crimp, clamp, or push-fit connections.
When you make a clean, square cut, the PEX tubing fits perfectly into the fitting, ensuring a tight seal. On the other hand, a jagged or angled cut can leave gaps, leading to leaks and potential water damage down the line. Plus, a clean cut prevents the tubing from deforming or collapsing, which can also compromise the connection. Think of it like building with LEGOs—if the pieces aren’t cut correctly, they won’t fit together snugly! So, taking the time to cut PEX tubing properly is an investment in the longevity and reliability of your plumbing system. Trust me, your future self will thank you for avoiding those pesky leaks.

First things first, you need to know how much PEX tubing you actually need. Use your tape measure to determine the required length, and then add a little extra (an inch or two) just to be safe. It’s always better to have a little extra than to come up short! Once you’ve got your measurement, use a marker or pencil to clearly mark the cutting point on the PEX tubing. Make sure your mark is clear and easy to see, so you can cut accurately. Think of it like marking a line on fabric before you cut—precision is key!
Step 2: Position the Tubing in the Cutter
Now, grab your PEX tubing cutter. Open the jaws of the cutter and position the tubing so that the blade lines up exactly with your marked cutting point. Make sure the tubing is seated properly in the cutter to ensure a straight cut. If you’re using a ratcheting cutter, ensure the blade is in the open position before you place the tubing. Proper positioning is crucial for getting that clean, square cut we’re after.
Step 3: Cut the Tubing
If you’re using a ratcheting PEX cutter, start ratcheting the handles. With each squeeze, the blade will advance further into the tubing. Continue ratcheting until the blade has completely cut through the PEX. The ratcheting mechanism makes this process smooth and easy, requiring minimal effort. If you’re using a scissor-style cutter, simply squeeze the handles together firmly until the tubing is cut. The key here is to apply steady pressure and let the cutter do the work. Avoid twisting or bending the tubing while cutting, as this can result in a jagged or angled cut. Remember, a clean, perpendicular cut is the goal!
Step 4: Inspect the Cut
Once you’ve made the cut, take a close look at the end of the PEX tubing. You’re looking for a clean, square cut with no jagged edges or deformations. The cut should be perfectly perpendicular to the tubing. If you notice any burrs or rough edges, this is where your deburring tool comes in handy. Use the tool to smooth out the inside of the tubing, ensuring a smooth, even surface for connecting fittings. If the cut isn’t perfect on the first try, don’t sweat it! You can always trim a little more off the end to get it just right.
Step 5: Repeat as Needed
Continue measuring, marking, and cutting PEX tubing as needed for your project. Remember to always double-check your measurements and take your time to ensure accurate cuts. The more you practice, the better you’ll get at it! Before you know it, you’ll be cutting PEX tubing like a seasoned pro.
By following these steps, you’ll be able to cut PEX tubing with confidence, ensuring a tight, leak-free plumbing system. So, go ahead and tackle that plumbing project—you’ve got this!
