Multiple Choice

The tool shown in the provided figure is used to?

Forming a flare on the end of a tube is the function here. A flaring tool shapes the tube end into a precise outward taper so it can mate with a flare nut and fitting, creating a reliable, leak-tight seal under pressure. This is common for copper or steel tubing in gas, hydraulic, or refrigeration systems, where the flare provides a strong, consistent connection without welding. The other options wouldn’t fit because cutting would just separate the tube, beveling would notch the end for welding, and reaming would remove burrs rather than shape a flare. The tool pictured is specifically for creating that conical flare at the tubing end.
