What step comes immediately after centering the plunger over the tube in the tubing flare process?

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

Answer: (B)

Centering the plunger over the tube sets up a symmetrical flare, but the immediately next move is to project the end of the tube slightly above the top edge of the flaring tool. This small protrusion provides enough material for the flare to form against the flaring cone, ensuring a proper, uniform shape. If the tube end is flush with the tool, the flare may form shallowly or unevenly, compromising the seal. After this step, the forming action (light blows or controlled pressure with the plunger) shapes the flare, and the tool’s nut and sleeve are already in place or positioned as required by the setup.
