I have all new hoses, compressor, evap, condensor. The only thing that I didn't replace was an all aluminum metal line. Its been discontinued and I can't find it anywhere.
After flushing multiple times there is still a slight black film in the line that i can wipe off with sticking a paper towel a little down the line.
Should I get a new custom line made? or will it be fine.
Its carbonized oil coking (heat and age buildup). Some of the material will enter the aluminum surface like anodizing, but it does not wipe off with a swap after flushing; and this would be OK. If you can wipe it, you may be using the wrong chemical (its not cutting it).
I need some opinions on this ASAP please. I have been without a/c for little over a year.
I have used Johnsens Mobil A/c freeze A/C Flush. I have used the orange smelling A/c pro stuff. and denatured alcohol to try and flush this all aluminum metal line. If I stick a cotton swab down in the tube and rub it around it comes out with a little bit of black on the swab. This line has been discontinued and I cannot find it online at dealerships or even someone that can custom make aluminum lines.
Its clean of all debris except this coating. It it still alright to use?
Here are some pictures.

You can clean quite a bit of it if you want to . Spray the inside with an oily solvent like PB Blaster & let it sit for a few minutes.
Go to the craft store, and buy some long pipe cleaners:

And scrub it from both ends. Then use a spray can of brake cleaner to blow out the gunk.
Whatever is left should not be an issue with a clean system.
