Aluminum AC Hard Lines

[tonyvol]

I'm trying to go from the number #10 fitting to the bulk head. I can't get a hose and fittings to work because it is kinking even though I'm using reduced diameter AC rubber lines. Do see any reason not to use a hard line? Will the low pressure side #10 hard line sweat? Do I need to be concerned about vibrations causing a leak since I'm going from the VA unit to the bulk head? Also, does anyone have a good idea on sealing the bulk head so that I doesn't leak? Not sure if 3M Strip caulk or silicone caulk will be fine.


Thinking about using this hard line.

Here are some pictures of my install.

Yes the 10 will sweat. Why not just run the hose from the unit straight to the compressor and replace the bulkhead fitting with a grommet?

So what if it sweats. Rubber will too, so insulate it so air doesnt get to the pipe then it cant sweat as bad.
I would prefer hard lines in most cases, less chance of leaks.
There are several ways to insulate, the black tar pack works well also and you could run some braided covering over it or colored or even split loom after insulating.
Also if its on inside it shouldnt sweat if system is working.
Some times I really dislike VA products, sometimes they just dont seem to be as well designed.
Again, the tar type insulator works well and you can cover it up.
And I do AC nearly everyday. well less in winter.
Heck I love making old stuff work better,, just helped guy mod his 63 Chevy to run with orifice tube, had him use self adjusting one and one of the aftermarket A6 replacements called SA6, made by Nipondenso. company is out of Texas I believe, worked great.

Hey guys, I may be able to get rubber AC hose to work. I was wondering if there is any reason why you wouldn't run rubber AC hose on the inside of car? Would hardline be better to run in the passenger compartment?

Either/or just protect rubber if it goes through sheet metal. Oh and I can get you an AC repair kit/parts to make lines and such let me know. Ill ask my supplier for price list on parts, pieces and tools. Most of its no brainer stuff.
