Step 1: Prepare the Copper Pipe

Cut square, clean thoroughly, and apply flux.

Step 2: Sweat the Copper Joint

Insert the copper pipe into the female sweat end, heat evenly, apply solder, and let it cool naturally.

Step 3: Prepare the PEX Tubing

Cut tubing squarely, then slide a crimp or clamp ring over it.

• Do not overheat copper when sweating the joint.

• Calibrate your crimp tool before each project.

• Support piping runs to reduce stress on fittings.

• Perform a pressure test before closing walls or concealing plumbing.
