Step 2 · Cut the Copper Pipe
Measure and mark the desired length on the copper pipe. Position the tubing cutter on the mark, with the cutting wheel aligned perfectly. Tighten the knob on the cutter just until the wheel makes firm 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 pipe snaps off cleanly. This method ensures a square cut, which is essential for a good fit inside the fitting.
