How to Cut and Crimp PEX Tubing Like a Pro · Step 5 of 6
In this video
Slide a new PEX crimp ring over the prepared end of the PEX tube. Then, push the barbed end of the new PEX shutoff valve into the tube until it is completely seated. You will feel a distinct resistance when it reaches the proper depth, indicating it is fully inserted over the internal barbs. Adjust the position of the crimp ring so that it is approximately 1/8th of an inch from the end of the tube. This precise placement ensures the ring is correctly located over the barbs of the valve for a secure crimp.
Goal: Dry-Fit the PEX Valve
- There will be resistance when you reach the proper depth.
- Slide the crimp ring into place approximately 1/8 of an inch away from the end of the tube.

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.
