    It seems to me like they are simply leaking, maybe just not properly crimped/installed had a minuscule leak.

    There was an error rendering this rich post.

    Propex if it is pex a tubing, but it probably isn't.

    Propex inherently crimps itself properly if you don't over-expand it, just need to cut the tubing square. You can move the tubing to a position where you can access it with the tool, expand it, then move it to its final position on the fitting.

    Look like that one ring was not crimped properly? The tool only crimped part of the ring by the looks of it.

    Copper Pex rings have been around 35 years or more, properly installed on tube that is in spec they should be just fine

    Expansion type fittings with composite materials for the fittings seem to have the best performance, larger ID.

    it seems like there is a lot of moisture around it. could be leaking itself, but also could be something near it leaking or condensing. maybe wrap it in saran wrap and see if water builds up underneath.
