3AN to 1/16" NPT

The 1/16" NPT threads seated perfectly into my fuel pressure regulator port with no wobble, and the 3AN flare end locked onto the line with a satisfying click. This little fitting solved the vacuum reference connection I was struggling with.

Machined cleanly, no burrs on the threads, and it sealed up with just a bit of PTFE tape on the NPT side. Exactly what I needed for a vacuum reference line on my fuel pressure regulator—fits snug and doesn't leak.

This brass adapter threaded perfectly into my aftermarket regulator, sealing without any Teflon tape needed. Makes connecting a standard 3AN line to a tight 1/16" NPT port much easier than I expected.
