In the tubing flare process, which action follows centering the plunger over the tube?

• A. Project the end of the tube slightly from the top of the flaring tool
• B. Slip the fitting nut and sleeve on the tube
• C. Strike the plunger and turn it after each blow
• D. Tighten the clamp bar securely to prevent slippage

Answer: (A)

Projecting the end of the tube slightly above the top of the flaring tool is the next step after centering the plunger because it provides a proper surface for the flare to form against. When the end sticks out just a bit, the flaring cone can shape the metal cleanly and create the correct flare angle and seating surface for the fitting. If the end is recessed, the flare can be shallow or crushed, leading to a poor seal. The other actions are part of setup before centering or are not typical for forming a single flare: sliding the nut and sleeve onto the tube is done before inserting it into the tool, striking and turning the plunger after each blow isn’t how a standard flare is formed, and tightening the clamp bar is done to secure the tube during setup rather than as a step after centering.
