6AN 公頭喇叭口轉 M16x1.5 公頭反向喇叭口轉接頭

Swapped out my old adapter on the fuel rail and this one sealed perfectly on the first try, no leaks at all. The inverted flare threads are machined cleanly and snug up just right with a wrench.

The inverted flare seat seated perfectly against my fuel rail, and the 6AN male flare end mated up without any binding. Threads were smooth all the way, so I didn’t even need thread sealant.

The M16x1.5 threads cut cleanly into my fuel rail without any binding. Swapping between AN fittings and metric hardlines has never been this straightforward.
