Product review (5 stars): Good supply lines.
I needed to switch the washer and dryer positions so the dryer could vent better, and these gave me the distance to do it. They are much nicer than the cheaply made rubber hoses. The rubber hoses wear over time and break down where the metal crimped connector fastens on. The metal jacket helps prevent damage to the line and provides support. Many hardware stores now days seem to only stock plastic supply lines.. Sometimes they have lines that look like they have a steel braid, when it is just plastic. These were fairly priced, being lower cost and better quality than many others I found.

Easy to install, and no leaks so far.
