Plumbing repairs on an RV fresh water system often run into a size mismatch, and this Flair-It coupling handles that by stepping a 1/2" line down to 3/4" (or the reverse) in one compact fitting.
It's built for the same push-style poly tubing systems commonly used in RV water lines, so you can make the connection without soldering, gluing, or cutting into more of the existing run than necessary. Keeping a few of these on hand makes future line repairs and reconfigurations much faster.
A handy fitting to have in the parts bin for fresh water line repairs or size adaptations.
