What type of bond is commonly used to connect PEX to copper pipes?

The common method for connecting PEX (cross-linked polyethylene) to copper pipes is through a crimp or clamp connection. This type of connection utilizes special fittings that are designed to securely attach the PEX pipe to the copper. The crimping tool compresses a ring around the PEX tubing and the fitting, creating a tight seal that prevents leaks and ensures a robust, long-lasting connection.

Crimp or clamp connections are preferred in these scenarios due to their efficiency and the ease with which they can be installed compared to other methods. They provide a reliable joint without the need for heat or additional supplies, making them ideal for a variety of plumbing applications.

Other methods such as solder, threaded, or glue joints are not suitable for connecting PEX to copper. Solder connections require heat and flux, which could damage the PEX material. Threaded connections are generally not practical for PEX plumbing, and glue joints, typically used for PVC or ABS, do not apply to the combination of PEX and copper. Thus, the crimp or clamp connection stands out as the most effective, practical choice for this application.
