Nicely explained. I have been useing the Loctite for many years without any issues. It is so much easier to work with; still have the PTFE for backup and as you said for sealing olives.

Twisting the PTFE tape into a cord and then filling the thread works best in my experience. That would give you a very similar outcome as using the Loctite.

As a fairly novice DIYer, the idea of any plumbing work brings me out in a cold sweat! This makes a lot of sense though. I've had my own struggles with PTFE in the past!

A better method is to wind the 55 cord into the thread, not crossing it as in this video. Then putting 2 or 3 winds of ptfe tape over if. Works real good, I'm putting pipe and valves together all day, every day.

I had a visibly squashed pipe feeding a rad (previous occupant had overtightened the compression joint). Would ptfe help the olive seel in that instance? Could i "reshape" the pipe somehow? I ended up trimming the pipe down and will solder on a bit more pipe to bring it back to the required length.

I'm a diyer... I've got about 8 rolls of bloody PTFE... I'll be lucky to use it up before I die 😂 (it's so cheap I might just give it away and upgrade to the loctite).
