Todd,

First of all, the neat Aeroquip A/C fittings are O-Ring style, not AN. We have used the hose and fittings and find that they are easy to assemble, look great, and had no leaks.

Given that, soldering AN or pipe fittings onto your existing lines may not be the way to go. Two ideas pop to mind; can you remove your existing evaporator and take it to an A/C shop who can put the proper O-Ring fitting onto it OR call Vintage Air and tell them what you want to do....they will probably have a solution.
