Thanks guys.
I've been reading a lot about home build airplanes (RV-7A to be specific)
and that's where I got the idea that Teflon tape was bad...... now I get it
........... in fuel systems.
What a relief....... I envisioned the hydraulic wonder I'm making working
only when it felt like it....... thanks to the Teflon tape.

I read somewhere that it's not a good idea to uses Teflon tape on threaded
joints in a hydraulic system.
Is that correct and if so, why?

Is it because tape can break off & clog the orifices, or, is it because
hydraulic fluid dissolves Teflon? (it seems to) ...... or are there other
reasons?
Pipe threading compound contains Teflon.
I'm wondering if I should take all those fittings apart and replace the
tape.
TIA
