PEX Crimp

The crimp connection method uses a copper ring on the outside of the pipe and an insert fitting that goes into the pipe.

To make a connection, start with a clean, straight cut on the end of the pipe. Then, slide the crimp ring over the end of the pipe and insert a fitting into the pipe. Slide the ring back toward the end of the pipe where the pipe and fitting overlap. The ring’s location varies based on manufacturer, so always refer to the manufacturer’s instructions.

After positioning the ring in the proper location on the pipe, place the head of a crimp tool around the ring and compress the ring until the tool stops. After making the connection, be sure to use a go/no-go gauge to verify a proper connection. Loose crimps can result in leaks, and crimps that are too tight can damage the pipe or fitting.
