I wasn't talking about putting seal on the threads you fool. Read & comprehend before replying.

Indeed.

Only if you make the mistake of assuming that using PTFE on threads is
an attempt at making a seal :-)

The reason PTFE on threads *can* be useful is as a dry, mess free,
lubricant, allowing tightening with less effort, and no squeaking and
groaning as they tighten.

Agreed, but that doesn't mean there's any point in putting anything on
the threads ... and I would never put a joint on a damaged pipe.

Yes, that's true. I put a very light smear of jet blue or boss white on
the sealing faces of the olive and a little of this invariably ends up
on the thread and acts as lube.

+1

If when tightening a compression join it squeaks and groans probably
means that the pipes entering the fitting are not truly in line with the
fitting bores. Possibly somewhat unavoidable in some circumstances when
repairing or modifying and existing installation and lubricating the
thread with ptfe tape can make the tightening of the fitting easier.

In the very many years of DIY plumbing I've noticed not all olives are
created equally.

Interesting issue yesterday.

After threats from domestic management, I finally got around to checking
and turning on the underfloor heating. Fair bit of white deposit around
the temperature control valve assembled as part of the distribution
manifold.

Supply pipe secured by conventional nut and olive to a threaded sleeve
screwed to the male input port on the valve. Whole issue larded up with
plumbers paste so I guess the installers struggled to get a seal.

Problem turned out to be a design/manufacturing defect in that the
sleeve was too long (or the valve thread too short) to compress an
internal sealing washer!

Turning a few mm off the sleeve seems to have done the job.

Please quote any text where TB mentioned threads. He mentioned
imperfection in pipes, and "Olives bend into place but their ability to
fill dents is limited".

You're slowly getting worse.

I understand that but it looks awful and amateurish. I would rather use
a grease or some other lubricant.

I guess in the OP's situation under the floor and out of the way it
wouldn't be an eyesore.

Then clean the pipe properly before fitting. If any damage beyond
cleaning, cut it back to good.

Tightening them till they groan is the way I'm sure they're tight enough.

Couldn't do that when changing a valve on a rad. - short pipe out of
concrete, so no room for another fitting.
I find that a smear of sealant on the thread reduces the friction and aids
correct tightness, rather like not letting friction in a thread distort
torque spanner use.

In the real world, old pipe is not perfect, tiny nicks & pits are normal, and the job still has to be done. With the addition of a tiny amount of gloop it's a good bit more likely to seal IME - but I'm not a pro plumber.

The threads don't have anything to do with it.

Any damaged pipe that coincides with a new joint should be chopped-off
and replaced, or "re-rounded", rather than bu&&ering about with "gloop"
in the hope that it works.

Most old pipe is imperfect, and IME glooped olives are quite reliable. I think maybe some are trying to reinterpret things.

If I came across a pipe so badly damaged it couldn't accept a fitting, I'd
replace it.

Do you have any insurance?

If a pipe is lightly damaged but can take an olive, it is simply an
insurance policy to add a sealant, just in case there is a void under
the olive.

What is so difficult about that?
