Step 2 · Cut the Pipe
Measure and mark the desired length on your copper pipe. Place the tubing cutter on the mark, with the cutting wheel aligned perfectly. Tighten the knob on the tubing cutter until it 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 cutter slices cleanly through the pipe. This method ensures a straight, square cut which is essential for a good fit.
