Working in a plastic injection molding shop many years ago, we had maintenance workers that would use teflon tape on flared hydraulic fittings. Other than it does provide a lubricated surface so the threads are lubricated, (no galling), it has no purpose to seal anything. BTW, when you're sealing hydraulic lines the pressure isn't 5 PSI, it's usually 2000-3000 PSI. Double flared joints seal fine at these pressures, 5 PSI is a walk in the park to seal.
The OP was probably correct, that the misalignment of the tube and fitting contributed to the leak, or there was some foreign material in the fitting mating surfaces. (not uncommon in automotive fuel systems).
Glad to hear the problem is solved......  |
im sure we would agree on a lot of things, mechanical & other stuff we cant talk about here...
we've just had some different opinions on a couple things, doesnt make either of us wrong, theres usually more than one way to skin a cat.
i used to work for a large injection molding company too that had some GM & ford contracts among many others, had many different positions over the few years i was there.
