In an emergency we use a wet mop thread which has been unwound to get a smaller thread and it usually works great, cotton preferred.
I learned about using cotton string around sink drain couplings a few years ago.
The Ace Hardware guy told me the old plumbers trick of over-wrapping the threads in string,
and the water would make it swell up, to stop the leakage..
It works great on low pressure drains.. But for 50 to 100 PSI? I don't know.

In any event, I'm gonna be heating with the old oil burner for a while..
It's uses oil, but not a lot. Plus, it's a HS Tarm multi-fuel and can
run on wood, coal, propane & etc. If the grid fails us again, we're good..
My hobby is installing & trying to repair mini-splits
EPA 608 Type 1 Technician Certification ~ 5 lbs or less..
