I did not know that Airstream uses plastic fittings instead of brass.
I used only brass fittings/copper rings when replumbing and haven't had a single leak.
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.

I agree that the ring placement is wrong.

I use the "pro" rings that have a collar at the end with an inspection hole. They are not idiot proof but they are "idiot resistant" and for a few cents more I figure it's worth it.

The plastic fittings are fine as far as leakage goes IME but they are not physically as strong as brass. The 90 degree elbows, in particular, can snap if the attached lines are pulled apart or together with force.

Pex- Clamps or Rings

Don't throw pex crimp rings or clamps under the bus. This appears to be an installation issue as referenced by others. I use both types of connectors with no issues at all. Proper setting and alignment are the keys. I do use brass fittings rather than plastic as I am not confident of their durability.

My '98 had all brass elbows from the factory. Surprised that they are now using plastic.

Thanks everybody. I've had 3 plumbing leaks in 3 months of original ownership -- all from sloppy workmanship (luckily I was in the trailer and caught them all at onset when they occurred). And as you've educated me here, it's also from the factory cheaping out on the components. I've seen lots of evidence of sloppy work. Thank you all for your comments -- it helps me know what to look for in future inspections.

I would spend more on better tubing, the PEX system is solid. I believe Wirsbo publishes no leaks in umpteen years of manufacturing.
