I've encountered several splice repairs made with a Dorman brand
compression fitting on automotive steel brake line. I was trained this
was not an acceptable or legal method of repair. I've found the DOT
regulation regarding splicing of tubing which states all fittings must
meet SAE Standard J512. This I can not find. Anyone familiar with the
SAE Standard and whether it allows for the use of compression fittings
as opposed to double flared fittings?

in line theres another 1..i always ran the whole brake line just to be
safe..

Actually I once had a leak in the line that runs to the rear brakes.
Turned out to be a very isolated bit of rust once I had pulled it all
out. Couldn't buy a piece of tubing long enough to replace the whole
thing so I just replaced a section of it, using proper fittings.

The Weatherhead catalog states specifically that compression fittings are
NOT to be used on steel tubing.

That's a pretty scary discovery. I am surprised they don't leak from the
get go.
It's not like flaring the end and using a union is all that difficult.

Just get the generic steel replacement lines with the fittings already
on them and bend them to fit. That's what i did on my old truck.
