Step 2 · Cut the Pipe
Measure your copper pipe to the required length. Place the tubing cutter around the pipe at the marked location. Tighten the knob until the cutting wheel just makes contact with the pipe. Rotate the cutter around the pipe, tightening the knob slightly (about a quarter turn) after each full rotation. Continue this process until the wheel cuts completely through the pipe. This method ensures a clean, square cut which is essential for a proper fit inside the fitting.
