Question 347General Subjects - QMED

The correct answer is A) flaring tool. A flaring tool is used to prepare the end of a copper tube by flaring it outward, creating a wider, funnel-shaped opening. This allows the tube to be securely fitted with compression fittings or other plumbing connections. Flaring the tube end is a necessary step to ensure a tight, leak-free seal when installing fittings on copper piping. The other answer choices are incorrect because they do not accurately describe the tool used for this specific purpose. A spreader, stretcher, or swaging tool serve different functions in working with pipes and tubing, but are not the correct tool for flaring the end of copper tubing prior to fitting installation.
