AN, and inexpensive doesn't go together. That is aviation stuff which isn't inexpensive. If it's really cheap, then it probably came from china. The best prices on REAL AN fittings is at Aircraft Spruce, and Specialty
I always made sure the fittings I used were Hard Anodized. The cheaper fittings are not.
No way I would use china made fittings even on my lawn mower...
