Step 2 · Cut Pipe to Length
Measure the required length of the copper pipe and mark it clearly. Place the tubing cutter on the mark, with the cutting wheel aligned perfectly. Tighten the knob until the wheel makes firm contact with the pipe. Rotate the cutter around the pipe, following the score line. After each full rotation, tighten the knob slightly (about a quarter turn). Continue this process of rotating and tightening until the cutter slices cleanly through the pipe. This method ensures a perfectly square cut, which is essential for a proper fit inside the fitting.
