Hey guys,
Somebody I know decided to use compression fittings to patch up a leaking brake system in a car. I have been told this is dangerous, and that it will not pass inspection, but can anyone explain to me why this is? I have been told double-flared fittings the proper fix, but why are compression fittings dangerous? Thanks in advance! :wink2:
A compression fitting is only rated for 100psi in normal use. So it's fine for fuel line repair. An automotive braking system can produce anywhere from 1200 to 2000 PSI. No legitimate garage would use a compression fitting on a brake line, though quite a few shade tree "mechanics" do. It will start leaking, or blow out, possibly causing a crash. So best advice is, DON'T DO IT.
