How do you pinch a clamp PEX without a tool?

Answered by Charles Pate

Pinch clamps are commonly used to secure PEX tubing connections, but in certain situations, using a pinch clamp tool can be challenging. If you find yourself in a tight space where there isn't enough room to maneuver a crimp tool properly, there are alternative methods to pinch a clamp on PEX tubing without a dedicated tool.

Before attempting to pinch a clamp without a tool, it is essential to ensure that you have the necessary skills and experience to do so safely. It's also crucial to follow any local plumbing codes and regulations to ensure the connection is secure and leak-free.

Here is a step-by-step guide on how to pinch a clamp on PEX tubing without a dedicated tool:

1. Prepare the materials: Gather all the necessary materials, including PEX tubing, pinch clamps, and a pair of adjustable pliers or channel locks. Ensure that you have the correct size of pinch clamps for your tubing.

2. Measure and cut the PEX tubing: Measure the length of the tubing required for your installation and use a PEX tubing cutter or a suitable cutting tool to make a clean, straight cut. Ensure that the tubing is free from any debris or burrs.

3. Slide the pinch clamp onto the tubing: Place the pinch clamp onto the PEX tubing, ensuring it is positioned correctly according to the manufacturer's instructions. Make sure the clamp is centered over the fitting or connection point.

4. Position the pliers: Take your adjustable pliers or channel locks and position them over the pinch clamp. Ensure that the pliers' jaws are parallel to the tubing and perpendicular to the pinch clamp.

5. Squeeze the pliers: Apply firm, even pressure on the pliers, squeezing the pinch clamp firmly onto the PEX tubing. Make sure the clamp is securely fastened and that it compresses evenly around the tubing.

6. Check the connection: After pinching the clamp, visually inspect the connection to ensure it is properly secured. Look for any gaps or signs of uneven compression. A properly installed pinch clamp should provide a tight seal around the tubing.

7. Test for leaks: Once all connections are made, it's essential to test for leaks. Turn on the supply and check the connection points for any signs of water leakage. You can also perform a pressure test to ensure the system is watertight.

While pinch clamps can be installed without a dedicated tool, it's important to note that using a pinch clamp tool is generally recommended for consistent and reliable connections. Pinching a clamp without a tool requires precision and care to ensure a secure and leak-free connection.

Pinching a clamp on PEX tubing without a tool is possible but should be approached with caution. Always follow proper installation techniques, adhere to plumbing codes, and ensure you have the necessary skills and experience. If possible, it is advisable to use a pinch clamp tool for more consistent and reliable results.
