I need a 3/4" thread coupling nut. I've seen the outside dimensions for this nut, but not the actual size of the threaded part.
Thank you for your question. The RP5861 coupling nuts are made to thread onto 1/2" male pipe threads. That is based on the inside diameter of the pipe. The outside diameter of 1/2" pipe is very close to 3/4"
