AC line and fitting sizes?
So, Im thinking of swapping engines in the future, and I know Ill be facing an AC issue. I dont want a relocation hassle, so the compressor will be low, and Ill need custom length lines. Itll be a 4th gen compressor, but 3rd gen everything else. Ive searched the swap forum, and most guys have a local shop make a set of lines, or just delete the AC. Im keeping my AC.
At docblocks.com, they have a 90 degree fitting for GM compressors, that states the sizes to be #8 with 3/4" x 16 tpi, and a #10, 7/8" x 14 tpi. I want rubber lines, but the tool to crimp the fittings is $500. Id rather not chase a shop down to make custom length lines (unless someone has a link to a good one that wont cost a fortune).
My question is, can I use a rubber hose (Like Earls pro-lite 350, rated at 350psi max press. and -40 to 300 deg f.) with the AN fittings, and adapt to the block from docsblocks? I use AN fittings all the time at work, but for aviation purposes, and mostly hard lines. I have assembled braided, high pressure hydraulic lines, but most aviation manufacturers give very specific perameters for their hoses. And a #8, would be 1/2" in AN, with a #10 being 5/8". Im assuming the extra 1/4" in each of the sizes listed above is the difference for the line sizes, as in: #8 line, into a 1/2" tube, thats flared to a 3/4" x 16tpi end.
Also, does anyone know the thread size and pitch for both ends of the lines. High side, and low side, from the compressor, to the evap, and dryer (I think, if memory serves me). My AC is hooked up and working, or Id just measure it.
