View Full Version : Where/How to make custom A/C Hard Lines?

With the serpentine swap complete, it has placed the compressor on the opposite side of the car. Also the condenser fittings are on the opposite side.
I am going to try and get a new condenser with reversed fittings, along with a few other items.

Custom hard pipes would really clean things up in the engine bay.

Any thoughts or recommendations?

I save any extra hardline stuff I come across so I can cut and weld to make up what I need. Not sure where to get a flare tool that does the ends. I'd like to know myself.

It is possible to use flare fittings for hardlines and hoses. Flares were used for years until GM went to a Tube-O fitting common thru most of the 90's. Recessed O-Rings were used in the early 90's to mitigate leaks caused by O-Ring nicks on installation, the lead-in pilot used to better align the O-Ring. The double O-Ring fittings in common use today is a further refinement to reduce leaks.

I had to relocate my AC dyer and used the aluminum U-Bend Em lines for Vintage Air. They are pre-made lines with the ends installed available in 12" increments up to 72". You can bend them with a standard tubing bender to make a custom fit. This was one I made up from a 12" U-Bend Em line. I painted it black to hide it behind the grille.

I see you are using a Vintage Air dryer. Can you tell me which one you are using as the only horizontal ones I see are polished or black anodized ones. I would also like to mount a trinary switch on it as you did. It looks like yours has fittings at both ends.

This is the replacement dryer I bought from Summit.

This is the same dryer but includes the trinary switch.

I may be wrong but I don't think his dryer is horizontal instead the picture is turned 90°.

That was a good catch! Its funny, on my phone the pictures are oriented correctly so I looked right past the horizontal part.

Having to cut and weld my #6 hard line coming from the condenser to the dryer. I have to ask, what technique are you using for the welds on the HVAC lines? Is this just standard TIG, silver hard solder/braze (doesn't look like it) or something else? Thanks for any info.

Thanks.

Definitely need to work on my TIG skills, two projects already pending that need it, and this makes three!

Man... you've got some advanced TIG welding skills. I switched from a driver's side V-belt compressor to a serpentine that puts the compressor on the passenger side, so I ordered new hard lines from VA.
