Which action is performed to prevent slippage during the tubing flare forming?

• A. Place the tube in the proper size hole
• B. Slip the fitting nut and sleeve on the tube
• C. Center the plunger over the tube
• D. Tighten the clamp bar securely to prevent slippage

Answer: (D)

During tubing flare forming, the tube must stay completely still in the tool as the flare is shaped. The clamp bar is what keeps the tube fixed in place against the forming force, preventing any movement that would throw off the flare’s angle or finish. Tightening the clamp bar securely creates a solid hold so the tube doesn’t slip while the die applies pressure to form the flare. Other steps, like getting the tube into the right-sized hole or sliding the nut and sleeve onto the tube before forming, are part of setup, but they don’t by themselves stop movement during the actual forming operation. Centering the plunger over the tube isn’t the primary action used to control slippage in this process.
