I use the cinch clamps as opposed to the copper rings and yes you can turn the fitting in the tube. An interesting thing is once you have cinched the clamp, carefully cut the clamp off. The tubbing remains compressed on the fitting and is almost impossible to pull off the fitting. I don't know if it will hold water or if it will relax with time but it does hold on to the fitting pretty tight.

I use the copper rings and can turn the fittings after they are squeezed. Turning them doesn't seem to create leaks.

If you cut the clamp or ring off, the connection will not hold water. If it does hold water, you are only lucky and your luck will run out.

You should have a test gauge. It simply slides over the crimp ring. If the crimp ring is to big then it's a failed crimp. I don't use plastic fittings but they might be ok. The important thing with plastic or brass fittings is they better not have any scratches. A Pex fitting will leak if it's scratched. So be careful with them. Don't leave them on the floor where they can get stepped on etc. If you keep them in their own [plastic]container where things aren't banging into them you will have less chances of problems. If they get dirty you can wash them but only use dish detergent and not any kind of solvent that I know of. Only use a clean rag or wash cloth and rinse them off well. I have salvaged brass fittings with minor scratches. But I had the micro mesh polishing system to do it with so I was able to get it to better than a 2300 grit finish. One good thing about Pex is that if it holds for ten mins it's probably good forever.

I don't do any repairs myself, but I can tell you that the little PEX-branded copper crimp bands that Airstream is using now: they allow leaks. I'm catching leaks after only 3 months of ownership. Maybe the craftsmen at Airstream were sloppy, but now I have no faith in my entire original pex system. I'm working with Abe of RV Mobile Service 2U to fix the problems.

Here, I'm pointing to a knuckle on the city water inlet pipe that started leaking today.

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.

Copper rings, with BRASS fittings.
