ISTR that TM used to install PVC pipe rather than PEX. Is the surface of PVC softer than PEX?

The fresh water supply lines attach to all the faucets with female threaded nuts. As best I could tell, they are 1/2" NPT, and so that's what I have successfully used to plug them.
I've used these, which I can confirm work under pressure (and which appear similar to what FlyBoy ordered):

...but I've also used a more freely available alternative, available at just about any hardware or plumbing store. And that solution is just using a 1/2" NPT PVC riser like this:

...with a 1/2" NPT cap, like this:

I've used both -- one in each of my TMs. Works like a champ, though it might be easier to get a good seal with the riser/cap assembly because the riser of hollow, and doesn't push up against the PEX inside the connection on the TM like the plugs do. But, both work, which is the only thing that matters, and since they would be infrequently (if ever) used, easier to use than installing a shutoff, the latter of which also introduces more places to leak.
