-8 ORB thread

[fordsbyjay]

I have some FAST fuel rails for a project. The ends are not tapped for fittings. I have some -6 AN flare to -8 straight cut O-ring fittings. My question is what tap do you use for the -8 straight cut O ring end? I have looked all over the interweb and can not seem to find any info ORB threads at all making me think it is something easy but I have no idea.

Below is a link similar to the fitting I am referring to.

Ask and ye shall receive...



As you can see in the chart, -8 uses a 3/4-16 thread.

I hope this helps.
