Using a pipe fitting crimping tool correctly is essential to ensure that the pipe and fitting are securely attached, preventing leaks and ensuring a long-lasting connection. While crimping tools are relatively easy to use, a few key steps should be followed to achieve the best results.

First, it is important to select the right crimping tool for the job. Crimping tools come in various sizes and designs, so choosing the appropriate tool based on the pipe material (e.g., copper, PEX) and fitting type is crucial. For instance, a PEX crimping tool is designed specifically for PEX fittings and will not be suitable for copper pipes.

Before starting the crimping process, make sure that both the pipe and fitting are clean and free of debris. Any dirt or residue can affect the quality of the crimp and lead to leaks. Insert the pipe into the fitting carefully, ensuring that it is positioned all the way into the fitting. It is essential that the pipe is aligned properly to avoid uneven crimping.

Next, place the crimping tool around the fitting and pipe, ensuring that the correct die is in place for the fitting size. Apply steady pressure on the tool's handles to compress the fitting onto the pipe. Make sure to apply enough pressure to create a secure crimp but avoid over-crimping, which can damage the fitting or the pipe.

After crimping, inspect the connection carefully. Many crimping tools come with a go/no-go gauge to check if the crimp is properly executed. If the crimp is too loose or too tight, it may not provide a reliable connection. A properly crimped fitting should show even compression and should not be easily removed by hand.
