How to Cut and Crimp PEX Tubing Like a Pro · Step 5 of 6
In this video
Once the valve is seated on the pipe, slide the PEX crimp ring forward until it is positioned correctly over the barbed fitting, approximately 1/8 inch from the valve body. Take the PEX crimping tool and place its jaws over the tab on the crimp ring. Squeeze the handles of the tool with significant force until it is fully closed. This may require using your body weight or knee for extra leverage. The tool will often click when the crimp is complete. To be certain, the host does two cycles. As soon as the ring is securely crimped, turn the handle on the ball valve to the closed position. This will stop the flow of water, completing the installation.
Goal: Secure the valve with the crimping tool and stop the water flow.
- A proper crimp is essential for a leak-free connection. Ensure the tool is fully closed and the ring is compressed evenly.
- Significant force is required to operate the crimping tool. Don't be afraid to use leverage to get a tight seal.

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.
