AN Adapter Fittings

You missed what I meant, what I was getting at is what are you connecting that needs 1/2NPT? That just seems like an odd combo?? I was thinking there might be a better way
Have to plumb from the pump to cooler and then cooler to filter/separator then into the compressor tank. Only thing that’s AN is the cooler. Tank is pipe thread with 45 degree compression fittings. I want to run rigid pipe because I have it. There’s a speed shop on the other side of town that has a lot of AN fittings in stock so I might be able to get them there
