What's up with the censorship?
... but before we get into that, I've been trying to find out what a -2 AN thread is. I've spoken with a few machinists who are extremely sharp and they gave me dumb looks. The local machine supply house didn't even know what it is. They went through a few supplier catalogs and couldn't find AN threaded fittings anywhere.
Can you help me out? Is that an American name for another type of thread? Does it have other names that locals might be familiar with?
I'm trying to find pitot adapter fittings locally so I don't have to absorb shipping on such a small item but it doesn't look good so far.
