Cutting a PEX pipe is simple, but there are a few things you should know to avoid leaky connections. Here are a few quick tips from John Woodard, our Master Water Specialist, for cutting PEX pipes and tubing. How to cut a PEX Pipe Tools needed: PEX pipe Pipe cutter or ratchet pipe cutter Three-quarter-inch PEX is easy to cut with a pipe cutter, especially one made to take the diameter of PEX tubing. A pipe cutter allows you to cut the tube straight without much effort. It works the same for large and small tubing diameters. The secret to cutting PEX: Make sure to get an even cut, especially if you're using a quick-connect fitting, a SharkBite fitting, or a JACO fitting. A quick-connect fitting cannot lock in place and create a seal with uneven tubing. If you're using PEX tubing with a larger diameter, like an inch or an inch and a half, it's best to use a ratchet cutter. A ratchet cutter cuts PVC pipes as well. Do's and don'ts when cutting PEX tubing Get a straight cut. Don't crack the tubing. Don't pinch the tubing. Don't create any angles.
