How to flare aluminum AC lines? - 07/01/14 09:35 PM
Anyone know how to put the correct flare on an aluminum AC refrigerant line? Does it require a special tool?

They really aren't flared.

Actually, let me ask another question. I was thinking of doing all my lines in hard line, but a friend of mine says I should go with hose because it has better insulating qualities. Any thoughts from anyone?

Matt, I had the exact same problem when doing final assembly on my challenger. I preferred the look of the hard line over the rubber hose where possible. As far as functionality, the rubber hose works just as well. To answer your question, yes you can put that type flare on aluminum a/c line using the proper tool. I suggest you rent or borrow one from your local HVAC repair shop, one similar to this: http://www.matcotools.com/catalog/product/AC71475/UNIVERSAL-HYDRAULIC-FLARING-TOOL-KIT/
A simpler way is to try to arrange your line placement to match preassembled hard lines available here: http://www.vintageair.com/2012catalog/20...age%2072%29.pdf
This is what I did on my Challenger, but I did have to cut and flare one end of one metal line:
