From a highly recommended source(https://www.aircraftspecialty.com/), Nothing on flared hose connections, Loctite 567 on NPT adapter threads.
So, I still have a can of this from the 80s. An old timer at that time suggested I buy it and it will last me a life time.
So for all of these years has this been the wrong stuff? Does this even have a place in aviation anymore?
My cupboard is staring to look like the shelves of an automotive store and is becoming more confusing on what does what. 565, 567, 56521, with PTFE etc. Anymore Im not even sure if we are talking about the same stuff or if there is dyslexia going on with the changes in the numbers and Im back googling to see whats what.

Yep, devil spawn lube.
Actually, that quote is attributed to H. L. Menken.

I don't use EZ-Turn, aka Fuel Lube on the airplane. However, I had a persistent drip from the oil filter on my 4x4. No matter how tight, it would drip. I coated the seal with a light layer and bingo. The oil drip is gone. And the filter is easier to remove.
A plumber was replacing a pump on our heating system and couldn't get the gasket to stay in place. I put a light film on both sides of the gasket for him and bingo. Problem solved. And before someone says anything, it's not potable water, so not a problem.
