I have used LS-X on a two 'tricky' connections that wouldn't seal (one a
plastic sink waste, the other a rad valve where the pipe was a bit on
the slant) it worked in both cases.

I have an ancient tub of Boss Green (which is currently separating, like
putty does), and it's generally worked well, although I find that for
high pressure, PTFE is more reliable. Sometimes I use both (paste
covered in tape), and that has never once let me down :-) I assume LS-X
is similar?

It certainly does after time. Got a part used tube which was solid.

Loctite 572 for coarse threads and Locitite 542 for finer threads (below 3/4
BSP).

I use them for water, gas, oil, compressed air and hydraulic fluids and
haven't had a failure yet (silly thing to say !!!)

That is likely true, but here it set in the tube enough to be useless. No
criticism of the product though, which is very good.

The Boss Green I have is like silicone-based putty. But instead of
having the linseed oil dry up, over the decades, it separates into what
I assume is 'siliconey' oil, and hard bits.

I always have a tube on hand for difficult situations... I generally
find I don't need it, but now and then its very handy.

What's your problem with PTFE tape? I always use tape intended for gas
connections - it's thicker and stronger than the standard stuff. Also,
when fitting radiator valve tails into new rads, I run a 1/2" BSP tap
into the hole first to make sure there are no rough bits on the thread.

Here's an "old and new" idea.....

My dad always used hemp and boss white on screwed joints, so I've modified
this a bit, and on awkward threaded joints (ie outside taps that inevitably
end up 30 degrees from where you wanted them) I use hemp and LSX. Jams
nicely where I want, no leaks (so far), and works well on rad tails too.

I've got enough hemp to last me 40 years at current limited rate of use, but
rather to my surprise found it's still readily available in hanks.

Just a thought.......

FWIW you can also use cheap rope in lieu of hemp. It degrades due to UV, which isn't found inside plumbing joints, and lasts well in the dark. I can't remember which plastic it was, PP I think, id the rope & check its properties online. PE I would not use.

Bryan Mitchell presented the following explanation :

contemplating the use of LS-X compound with my new radiator valves, and I
would value comment on this please.

Plumber's Mate was suggested to me, as able to seal the impossible. I
spent two days struggling to get a seal on two wash basin drains, I
tried PTFE, Boss White - neither worked, but PM did first try. Its a
none setting sort of mastic, difficult to get it to stay put on the
thing you are trying to seal, it prefers to pull back off on your
fingers, but if you persist it is squishy enough to seal any gaps in
your application. Unlike Boss White, it doesn't set in the pot.

I used what I bought around three years ago, to TV's all round my
heating circuit. I filled up and tested for leaks today, there were
none.

Sealant tends to end up like little rubbery soft balls I find in this sort
of context.

Just stir and mix it. It will come back to life just like

You are wrapping it the right way round the tail so that the action
of screwing it in tightens the tape on to the tail rather than
loosening it. And you are putting enough turns on, lightly tensioned?
"enough" being enough to fill the threads.

Boss White is linseed putty, just thinner than the glazier's version. Too thin imho.

I do, but it takes a bit more than stirring :-) More a sort of
prolonged chopping action with a small scraper.

Unlike a modern equivalent of Boss White that states its life to be 1 year
from /date of manufacture/ and /if unopened/! (so it could be u/s from
'new'), I found a can of Boss White under the hedg at the top of the garden.
Knowing when the main supply had been repaired, that can had been there for
~15 years. It had a rusted hole in it, the contents were more encapsulated
than sinned over but, inside, it was still useable.

Boss white was intended to be used with hemp string to seal threaded
joints. It works then.

PTFE tape is miles better.
