The list does not indicate which threaded connection it is about. This is NOT an NPT thread, it may be black iron pipe thread. Also, there was a dirty first thread on all ends that was cut in one piece into a thin 1/4 inch point. With the exception of the first thread, the rest of the parts are of good quality.
