Continued from my previous thread: Plans for 90 civic A/C rebuild with newer gen Sanden compressor - remaining questions

The cleaned-up end looks pretty good. But from what I can tell, it still shows some pitting and an indentation where the o-ring goes. I would replace the line if you can locate one. Nothing worse than having to repeat the job due to a questionable component that fails right after completion.

Agreed. While that line is discontinued, it supposedly was the replacement for three other Honda part numbers, and all three of those are still in stock (whew), so I will be ordering it.

For peace of mind, I think buying a new line will be money well spent.

So far no luck in getting any replacement for that line, so I am wondering about repair. I found a short piece of hardline with a female o-ring fitting like this:

I would think that cutting off the old end and replacing with the above should be easy, but how best to splice this? Could it be butt ended to the other piece and brazed, or would some sort of coupler be a better choice?
I was hoping to find a fitting with an expanded tubing end to slip over the other piece for brazing, but can't find such an animal?

Any suggestions?

Good idea about brazing-on the short length of line to renew the o-ring fitting. However, it will be impossible to butt the new piece to the cut-off original line and then braze them.

A better idea, I think, is to cut-back the original line to a solid, un-corroded area (or equal to the length of the new piece), swage the original line about 1/2", slide the new section into the old, then braze them. Fairly inexpensive tools are available to do the swaging yourself, which is the key to making this work.

I wouldn't use a compression fitting to join the two lines because of leakage concerns.
