Just Googled 3/8" inverted flare hose barb.

Found this Dorman, on the O'Reilly site. The thread size listed is "3/8". So, how was I supposed to know that the thread size was NOT what is listed, but is actually 5/8"-18 ?

And you can buy one of these from lots of places. But, they all show 3/8" threads. So, if you don't know that it actually has 5/8"-18 threads, how are you supposed to know that it is what you need ?
