AN fitting oil leak

phunk

If you take one of the NPT to flare adapters out of your oil sandwich... take a good look at the angle of the flare. I wonder if you somehow got SAE flare adapter instead of AN flare.

The SAE flare is 45 degrees... so if you lay it on the table on its flare, 180 degrees from where its touching the table would be standing straight up and down.

Hard to describe lol... but its possible since the 3/4-16 thread of a -8AN is also comes in SAE 45 degree flare fittings.

Got a way to measure the flare angle? I am with you that this fitting must be the trouble since you have tried multiple hose ends. Now I am intrigued as to why you have a leak.

I was going to swap the NPT to flare adaptors to see if the problem moves, but I don't want to disturb too much before heading to Z-Fest tomorrow. I will order new fittings for the sandwich plate and compare everything once they arrive. I had no idea the flare was available as SAE 45 degree flare. I'll take photos for everyone to.

Ya I have never knowingly encountered a SAE 45 degree flared fitting... but I looked them up really quick yesterday to see if it was possible and found that there are fittings made that look identical to what you have in there only with a 45 degree flare. Perhaps a mix-up at the manufacturing facility packaged your fitting a -8 AN... just randomly speculating here.
