To add to Bob Mariani's post, there is a difference between flare connectors used for gas, water, and high pressure, and there are two different types of flaring tools the one shown above and the double flare tool sets used for steel hydraulic lines.These are called flaring tools and are used for soft copper usually for gas lines. But for water lines also.
