Don't use the "O" rings. You either have a score on one of the mating surfaces
or the new line is not allowing the two surfaces to mate properly. Either the
threads are not right or the angle of the surfaces are different. The system
was not designed for the "O" rings. You're only asking for failure from
eventual cutting of the ring form vibration or eating away from the fluid. Are
you sure the threads were tight? Check the flare on the steel line for
deformation. Over the years they
sometimes wear and will only fit the old hoses as they wear together.

Subject: Brake Fitting Seepage
Listers:
I bought new lines that run from the flexible hose to the calipers on my 65
4A - got them from Moss. And when I lightly stepped on the brake to check for
leaks, I certainly got what I was looking for. The fluid spewed from bewteen
the threaded part and the line itself. Does this need an additional seal of
some sort. I found some small o-rings at Home Depot that fit just over the
flare and look like they might "seal" things. Notwithstanding the "eating"
ability of the fluid, will that work? Is it (or something else) necessary or
have I just done soething wrong?
Earlier, I put the repaired Master Cylinder back in and bought some new line
from DAP. I had the same thing happen (leaks between the fitting and the line
where the line goes into the MC). So I put back the old (original?) line
running from the MC to the three-way connector. It doesn't leak.
Do the newer lines not work? Are they incompatible with the original
lines/parts? Do I need the o-rings?
TIA
