Hi VAF,

I'm looking for a quality 90 degree -6 AN-NPT fitting with a "sweep" or radius to it for lower pressure drop.

Something like this, but from a quality manufacturer:

Any ideas?

I used these in my fuel system.

Curious on how you would tighten this fitting with no flats, vice grips

Screw on a nut and use the hex faces.

Any reason you can't use a straight adaptor and a 90 degree hose end? Your probably only going to find something like that in automotive "AN Style" fittings, which quality is a **** shoot. I would first see if known name brand like XRP or Earls or Goodridge makes it. If you have to go with the mystery chinese made part, I would buy a couple and have a machinist friend mic the threads and find one that is close to the class 3 fit a real AN fitting would have. Its still going to be made of mystery metal with no traceability, but at least it would be machined correct.
