Pex stop valves?

I'm running my PEX now, and need (or want) stop valves at the various fixtures like sinks and toilets. What I've done in the past was use a drop ear elbow with a piece of pipe and then a chrome stop valve. I see that they have chrome stop valves that PEX goes on directly, but I don't see how these are secured in place. It seems like with PEX on one end and a flexible supply hose on the other, it would tend to flop around when you use it. Am I missing something here? They would be cheaper, plus less joints to fail, but I don't want a flimsy installation. Anyone use these? Thanks!

They get secured by either using Crimp fittings over them, or using Shark Bites. Personally if you are using Pex, use the proper crimping tool, and crimp the fitting for the shut-offs like you would for T's and 90's. Most plumbers though, will stub out with Copper from the Pex to the fixture, vs. using Pex all the way. Better going that route, then you do not have a lot of flex on the line, and the possibility of the shut-off coming loose.

When you stub out pex- attach the pex stop close to the wall or floor using a standard cinch or crimp ring.
This keeps exposed pipe to a minimum- which is good practice and workmanship.

Lot's of plumbers stub out pex for supplies- copper stubs are fine if you want to spend the money- IMO, really no need to, it's a personal choice- nothing more.
There are fastening systems to hold pex rigid without the need for copper.

You can also use iron pipe stops combined with a pex adpter. This will make it simple to change an angle stop should one fail in the future.
