Got oil cooler, now what size fitting?

Take the cooler to your local Aeroquip or Parker store. They will have a
fitting to match the cooler. They would be able to assemble a hose with
fittings that will couple directly to whatever you have at each end.
Yes AN fittings are totally different from pipe threads.

The thread on the cooler is the size of a 1/2" bolt, so does that >mean -8
AN, or do I need some sort of Flare-to-Pipe adapter piece first?  Which
reminds me, what exactly are these for?  Are AN threads >different than pipe
threads?
