As many of you know FDNY has always utilized its own hose coupling thread. Never made the switch to National Standard Thread (NFPA). I am told that Chicago also has its own thread. While out teaching various departments in the late 80's and early 90's I found out that Cleveland, Cincinatti, and Pittsburgh also utilized their own non national Standard threads. Don't know if Cleveland, Cincinatti, and Pittsburgh still use their own ? So what other departments have their own hose coupling threads that are not NFPA 1963 compliant?
