How to Cut and Crimp PEX Tubing Like a Pro · Step 4 of 6
In this video
Firmly push the PEX tubing into one side of the push-to-connect coupling until it clicks or is fully seated. Then, align the other side of the coupling with the prepared copper pipe and push it on with steady pressure until it also clicks into place. Ensure both pipes are inserted straight to avoid damaging the internal seals. Gently pull on both the PEX and copper pipes to confirm they are securely locked into the fitting.
Goal: Join pipes
- A distinct click or a hard stop indicates the pipe is fully seated in the fitting.
- Do not use any lubricants or sealants on push-to-connect fittings; they are designed to seal on their own.

FAQs
Why is using a go/no-go gauge so critical after crimping PEX, and what does it tell me?
The go/no-go gauge is essential for ensuring your crimp connection meets industry standards and is leak-proof. The 'go' side should fit over the crimp ring, and the 'no-go' side should not. This confirms your crimp is properly sized and secure, preventing costly leaks down the line.
What are the most common mistakes beginners make when crimping PEX tubing, and how can I avoid them?
Common mistakes include not cutting the tubing squarely, placing the crimp ring too far from the end of the tubing, or failing to use the go/no-go gauge. To avoid these, ensure clean, square cuts, position the crimp ring about 1/8 inch from the end of the tubing and over the barb, and always verify your crimp with the gauge.
The materials list both PEX-A and PEX-B tubing. Does the type of PEX tubing (A or B) affect how I use copper crimp rings?
While copper crimp rings primarily use barbed fittings that are compatible with PEX-B and PEX-C, they can also be used with PEX-A tubing. The crimping method itself remains the same for all PEX types when using barbed fittings and copper crimp rings, but PEX-A is also commonly used with expansion fittings.
How accurate is the 'beginner' difficulty rating for this project, and what's a realistic time estimate for a first-timer to get a good crimp?
The 'beginner' rating is accurate as the steps are straightforward once understood, but practice is key. For a first-timer, expect each connection to take 10-15 minutes initially as you get familiar with tool handling and positioning. With a few successful crimps, your speed and confidence will quickly increase.
