Hi Tom,
I don't have anything to add to the other comments regarding original
source and alternatives. But I will point out that teflon tape is
useless as a sealing medium
in compression fitting applications.
In pipe thread (NPT) applications the thread contact surfaces make
the seal, in compression fittings the threads simply afford a clamping force.
In other words, don't try to fix this problem with a thread tape solution.

New issue for me, but I hope others have run into this. Alera has a
pressurize potable water system. It uses grey colored hoses and
fittings throughout. All appear to be original except for those
around the three way valve I replaced a few years ago. One (or
possible more) of the "T" fittings where the hot and cold water runs
split behind the sink to go to the sink and shower in the head have
small leaks. Here's a picture -

The leaks are not enough to be a huge problem in terms of volume.
But, they leak out from behind the bulkhead into the floor of the
head scandalizing the Admiral and making gett8ng them fixed a high
priority. Also, I suspect that I may have, or will have, similar
issues at other junctures that I have not discovered yet. According
to my brother, who has a CS40 at Niagara on the Lake with a similar
set up, this grey stuff was all the rage, including in residential
applications, until they learned that it started to deteriorate
after 20 years or so, developing hair line cracks and leaks. The
company is now out of business, of course.
These are in a difficult location and appear to have been done
originally without any silicon tape sealant. I can probably get a
wrench on them but am worried that if I can to either tighten them
or loosen them to put on the tape sealant before tightening em back
up until they stop leaking, they'll break. Thus, turning a small
problem into a big one. Now to my actual question...
What do you think of using a sealant on these after a thorough
cleaning and drying process?
Has anyone done this successfully?
If so, what did you use?
If not, (this ought to be a good one) what sealant would you suggest
I try? (My Brother Tony suggested 3m 4200, but I'm not sure about that one)
As always, suggestions, stories and wise-assed remarks are all welcome!
thx
