Two technicians are discussing the use of flaring tools. Technician A says that flaring tool is used to form the end of piece of copper tubing to allow it to be connected using a flare nut and fitting. Technician B says that a double flare is used on connection that will be repeatedly loosened and retightened. Which one of the following statements is correct?

To determine which technician is correct, let's first understand what a flaring tool and a double flare are:

1. Flaring Tool: A flaring tool is used to create a flare, also known as a flange, at the end of a copper tubing. This flare allows the tubing to be securely connected to another component, such as a flare nut and fitting.

2. Double Flare: A double flare refers to a specific type of flare that is used on connections that will be repeatedly loosened and retightened. The double flare provides a stronger and more durable connection compared to a single flare.

Now, let's evaluate each technician's statement:

Technician A says that a flaring tool is used to form the end of a piece of copper tubing to allow it to be connected using a flare nut and fitting. This statement is correct as a flaring tool is indeed used to create a flare on the tubing, allowing it to be connected to other components with a flare nut and fitting.

Technician B says that a double flare is used on connections that will be repeatedly loosened and retightened. This statement is also correct since a double flare provides a more secure connection, making it suitable for connections that may need to be frequently loosened and retightened.

Therefore, both technicians are correct in their statements. The correct statement is that both Technician A and Technician B are correct.
