Not quite sure why all the experimenting.
the 577 is closer to ez-turn gooish consistency and based on the spec sheets, a similar fit as the 567, if not better.
Look at the spec sheet, it says specifically UNLEADED fuels. Nothing about 100LL.
which does not automatically imply that it must be incompatible to leaded fuels...
maybe it's missing in the list simply because there are no more leaded fuels (except one called AVGAS...)
anyway, i can only speak for our brake system, but that one holds up well so far, better than ez-turn in any case.

I used the EZ Turn and ended up with a couple of leaks. I took the brake system down and reinstalled the fittings with Locite 567. Since then I have had no problems.
Why use anything? Transport category aircraft 3000psi systems don't use a thing. If the parts are properly formed / assembled they won't leak. If it does you screwed something up.

In process of draining and reinstalling with lt567.
Properly installed NPT fittings still need to be very tight to assure a good seal. Between 1.5 and 2 turns after finger tight. If not, it can still leak regardless of what thread sealant you use.
