I'm working on a customer's reg and I'm taking apart the post body to redo a custom manifold configuration and this is what the nipple looks like. None of the nipples I've seen have that bit sticking out at the end of the threads like that. It almost looks like a flare fitting but it's not big enough. The threads on the fitting and the female port don't look stripped or cross threaded so it's very likely that it is 1/8 npt but just wanted to make sure because there are some threads that aren't tapered the same as npt. any thoughts?
