Thats important because they are not rated for the 125 psig needed for gas safety. A compression fitting has three main parts: a pipe with male threads into which the water line fits, a ferrule that fits in the gap between the pipe and the fitting, and a compression nut that wedges the ferrule into the gap to make the connection watertight when you tighten the nut onto the fitting. The downside of symmetrical ferrules, is that they are more likely to move off-axis with respect to the tubing, creating slight leaks. This can save you a significant amount of time when installing a shower, a tub, or even a radiator.
