What tool is used to cut copper pipe cleanly without burrs?
Answer: Pipe cutter (tube cutter)
A pipe cutter (tube cutter) uses a hardened wheel to score and cut copper pipe cleanly with minimal burring, rotating around the pipe until it cuts through.
What is the purpose of a pipe reamer or deburring tool after cutting pipe?
Answer: To remove the interior burr left by cutting to restore full flow area
A reamer removes the interior burr created by a pipe cutter, restoring the full bore diameter and preventing the burr from causing turbulence or catching debris.
What tool is used to thread the inside of a pipe fitting to accept a pipe nipple?
Answer: Pipe tap
A pipe tap cuts internal threads (female threads) inside a fitting to accept a threaded pipe, while a die cuts external threads (male threads) on pipe.
What is the correct way to use Teflon tape (PTFE tape) on threaded pipe joints?
Answer: Wrap clockwise in the direction of the threads (2–3 wraps)
Teflon tape is wrapped clockwise in the direction of the threads (2 to 3 wraps) so that tightening the joint winds the tape tighter rather than unwinding it.
What is a pipe wrench used for and what materials should it NOT be used on?
Answer: Gripping and turning threaded metal pipe; should not be used on chrome or polished finishes
Pipe wrenches grip threaded metal pipes with toothed jaws; they should never be used on chrome, polished, or soft finishes as the teeth will permanently damage the surface.
What does a plumber use to solder (sweat) copper pipe joints?
Answer: Propane or MAPP gas torch, solder, and flux
Sweating copper pipe requires a torch (propane or MAPP gas) to heat the fitting, flux to prevent oxidation and draw solder, and lead-free solder to fill the joint.
