I would not be suprised if the plastic fittings leak. It also looks like the ring might be placed incorrectly on the leaker, too far from the end of the tube.
I agree. That ring is too far from the end of the tubing.
I used brass fittings and copper crimp rings on PEX tubing for a complete replacement of our trailer's original water system back in 2008, and there have been no leaks in the PEX fittings.
It's a good system, but it doesn't tolerate sloppy installation.
