What sort of reputation to these have? I like the idea of a push-to-connect copper to CPVC, but is it good enough to bury in a wall?

I like them, but keep in mind they provide an oppurtunity for the pipe to rotate in the fitting.
A tee in a horizonal plane will not support the weight of a valve stubbed out.
There is a possiblity that the o-ring seal may be affected by water with high chlorine. But I haven't heard of anyone having this problem so far.
How about a half answer that bumps this up again?
I used two of the plastic valve ones from Watts to cap 2 lines (1/2 and 3/4) while I did some demo and reconfiguring. They were on there for 3 months and there was never a drip. Since then I've found a supplier for the brass ones and they are much more substantial. Frankly if we are burying PEX connections in the wall, I don't see why you wouldn't feel as good using these in the same application.
Someone will have a better explanation about the longevity of solder v. a rubber o ring, but from what I've found, they work as advertised.
Hope that's helpful.
I sent some one to town for parts while I drained and replaced a hot water tank and he came back with shark fittings. While we were refilling the tank I could hear air being expelled around the fitting, which was disconcerting although it didn't seem to leak water when full.
I worry that in situations when there is lateral pressure at the joint ( like when you try and line up a new hot water tank with existing plumbing) that a gasket isn't the ideal solution.
I think I'll stick to compression fittings for similar situations. I just don't trust the sharks, and they cost me over ten bucks each.
The design has been around long enough.
I have done that style of connection on drinking fountains for years.
But I'm Leary about burying that fitting in a wall & walking away from it with any type of confidence.
I fear no man & only one GOD. Me
I used 'em for the first time last year, to tie new copper into existing PEX supply lines while doing a bathroom remod which required what wound up being essentially a total replumb.
They seem to work as advertised; they're expensive; and I have successfully returned to one and popped it off and back on again to add a second bathroom into that system just last month. No leaks.
Yet.
I wouldn't bury it in a wall. Hell, I wouldn't bury a PEX joint in a wall no matter what kind of joint it was. But then, we all know I'm a big chicken, LOL....
