I could be mistaken but I believe PEX has been the dominant type of pipe used in new water systems over the last 15 years or so. There’s not really any plumbers tape involved with the various types of fittings that are used with those pipes.


Connecting the pipes, no. but connecting fixtures to those pipes, yes. Showerheads, faucets, etc. will all be screwed on and sealed with PTFE.


I have seen plumbers that are still using hemp.


That's exactly what I did with all my faucets.

Call me paranoid but I've taken them apart remove all the mangled PTFE tape and sealed the thread with hemp.
