How do you pinch a clamp PEX without a tool?

Answered by Robert Golston

Pinching a clamp on PEX without a tool can be a bit tricky, but it is definitely possible with the right technique. Here are some steps you can follow:

1. Prepare the PEX: First, make sure the PEX tubing is cut to the desired length and properly deburred. It's important to have a clean and smooth surface to work with.

2. Choose the right type of clamp: There are two common types of clamps used with PEX tubing – cinch clamps and crimp rings. Cinch clamps are often easier to work with when pinching without a tool, as they can be easily removed if needed.

3. Position the clamp: Slide the clamp onto the PEX tubing, ensuring it is positioned correctly over the fitting. Make sure the clamp is centered and aligned properly.

4. Pinch the clamp: Using a pair of adjustable pliers or tongue-and-groove pliers, grip the clamp firmly. Apply pressure evenly on both sides of the clamp and squeeze it together. Be careful not to squeeze too hard, as it may damage the clamp or the tubing.

5. Check the connection: After pinching the clamp, visually inspect the connection to ensure it is secure and properly sealed. You can also perform a pressure test to check for any leaks.

It's important to note that pinching a clamp without a proper tool may not provide the same level of reliability and consistency as using a dedicated PEX tool. If you are working on a project that requires multiple connections or if you want to ensure a professional-grade installation, investing in a crimping or cinching tool would be recommended.

Personal Experience: I have encountered a situation where I had to pinch a PEX clamp without a tool due to limited space. I was installing a new line in a small utility closet, and there was very little room to maneuver a crimping tool. In this case, I opted for cinch clamps as they are easier to remove if needed.

Using a pair of adjustable pliers, I carefully pinched the cinch clamp onto the PEX tubing. It took a bit more effort and precision compared to using a proper tool, but I was able to create a secure connection. I double-checked the connection by performing a pressure test and inspecting for any leaks. Fortunately, everything held up well.

While pinching clamps without a tool can be done in certain situations, it's important to consider the limitations and potential risks involved. If you're unsure or if the installation requires multiple connections, it's always best to use the appropriate tool for the job.
