How Do You Use a PEX Crimping Tool?
PEX (Cross-Linked Polyethylene) tubing has become a popular choice for plumbing systems due to its durability, flexibility, and resistance to freezing temperatures. One of the essential tools for working with PEX tubing is a PEX crimping tool. In this article, we will explore the step-by-step process of using a PEX crimping tool.
What is a PEX Crimping Tool?
A PEX crimping tool is a specialized tool designed to crimp the ends of PEX tubing to secure them to fittings, valves, and other plumbing components. The tool uses a mechanical process to compress the tubing and create a secure connection. The crimping process ensures a watertight seal, which is essential for preventing leaks and ensuring the integrity of the plumbing system.
Preparing the PEX Tubing
Before using a PEX crimping tool, it is essential to prepare the PEX tubing. Here are the steps to follow:
- Cut the PEX tubing to the desired length using a PEX cutter or a tubing cutter.
- De-burr the ends of the tubing using a deburring tool or a file to remove any sharp edges or burrs.
- Measure and mark the tubing for the correct crimp location using a measuring tape and a marker.
Using the PEX Crimping Tool
Now that the PEX tubing is prepared, it’s time to use the crimping tool. Here’s a step-by-step guide:
- Insert the tubing into the crimping tool, ensuring it is seated properly in the tool.
- Position the crimp ring on the tubing, making sure it is aligned with the marking made earlier.
- Crimp the tubing by applying gentle pressure while turning the handle of the tool clockwise. Do not overtighten the crimp ring, as this can damage the tubing.
- Check the crimp to ensure it is secure and evenly spaced. A proper crimp should be symmetrical and not bulging.
Types of PEX Crimping Tools
There are different types of PEX crimping tools available in the market, including:
- Manual crimping tools: These tools require manual effort to crimp the tubing.
- Power crimping tools: These tools use a motor to crimp the tubing, making the process faster and easier.
- Hybrid crimping tools: These tools combine the benefits of manual and power crimping tools, offering a high level of precision and ease of use.
Common Mistakes to Avoid
When using a PEX crimping tool, it’s essential to avoid common mistakes that can lead to leaks or other issues. Here are some common mistakes to avoid:
- Overtightening the crimp ring, which can damage the tubing.
- Insufficient crimping, which can lead to leaks.
- Incorrectly positioning the crimp ring, which can cause the tubing to bulge.
- Using the wrong type of crimp ring, which can lead to compatibility issues.
Table: PEX Crimping Tool Specifications
| Tool Type | Crimp Ring Size | Crimping Force | Weight |

| Power | 1/2" to 1" | 500-700 psi | 10-15 lbs |
| Hybrid | 1/2" to 1" | 300-500 psi | 5-7 lbs |
Conclusion
Using a PEX crimping tool requires attention to detail and a thorough understanding of the process. By following the steps outlined in this article, you can ensure a secure and watertight connection between the PEX tubing and fittings. Remember to avoid common mistakes and choose the right type of crimping tool for your specific needs. With practice and patience, you’ll become proficient in using a PEX crimping tool and enjoy the benefits of a reliable and efficient plumbing system.
