A/C Line Fittings Thread/Pitch

[maan1986]

Does anyone know what the thread/pitch of the A/C line fittings are for the following:

-Low pressure line at the evaporator
-High pressure line at the condensor (which goes to the H side on the factory compressor)

I'm assuming they are standard pipe threads? Maybe I can just take the pieces I have down to Lowe's and test fit them if anyone doesn't know.

I would not assume that. I have never seen pipe threads on automotive AC piping.
