Does anyone know where I can get flexible AC lines? something like the one that runs from the compressor to the aluminum hard lines.

 

Lots of auto parts stores are able to custom make hydraulic lines and such so I would inquire if they could do an AC line. Maybe also try a hydraulic or plumbing shop...

 

I was thinking that but all the AC lines I've seen use that aluminum and I don't really know what the flexible part is made out of. It makes me think that maybe the refrigerant is more permeable than most hydraulic fluids.

 

the rubber hose is a special hose specifically made for refrigerant. A place that makes hydraulic lines will be able to connect the rubber line to the hard line. If you go that route, the best way to do it is to bring your old line in so they can match the bends in the hard line.
