can an a/c shop put this flare on a hard line? Mine broke off & a new line is big $$$.

Look identical to the saginaw fuel fittings to me, and since those can be made with a mcmaster-carr tool, a decently equipped shop should have no problem forming it I would imagine.
 
With a specialized tool, yes. On the left fitting in the picture, where the green o-ring is slightly visible, the white ring behind (to the left) of the o-ring, in front of the fitting, is actually part of the AC line that is pushed back to form that bulge.

Can't tell from the pictures, but those lines might also be slightly flared towards the open end as well, but I think that is to help keep the o-ring from falling off, thats all.
 
yeah, it's not a standard 45' or 37' flare...the tube is basically straight with the ring "squished" onto it. The one I need is the high pressure line for the rear a/c in my 'burb...


I'll try the salvage yard tomorrow...
 
Is that ring pressed into the line, or is it part of the line?

Never dealt with that style fitting on a vehicle, so that would be new to me.
 
Yeah, its technically not a flare. You would say the line has been "upset". It just acts as a surface for the nut to compress the O ring with.

Junkyard is the best. It is possible to splice that line with no leaks, but its tricky on the high pressure side especially.

You cut the line, and use special high pressure rubber hose with multiple clamps.
Some people put an actual partial flare to give the rubber something to bite into.
