flush is a cleaning prep step for the new compressor.
it's a small step, that requires completely blowing out ALL residue/oil/flush chemical from the lines with dry nitrogen.
once this is complete, all the o-rings in the car need to be replaced, then the oil, and compressor and reciever get installed, and pressureized with nitrogen to verify it's leak free. then that needs to be removed, and the system totally evacuated and THEN the system gets charged with refrigerant.
R12 would be my choice of refrigerant though.
