Well I’ve seen the question a few times with no real answer. It’s not npt. It’s straight cut 3/4” 16 threads. Amazon CCCP central has them for 10$. I had to bush fix a old dodge plug brazed to 3/4” 16 straight thread for emergency to get running ended up working perfectly. Hope this helps someone especially after my original snapped when installing after oil change.
