What is the purpose of a higbee cut in coupling threads?

The purpose of a Higbee cut in coupling threads is to facilitate easy connection. The Higbee cut is a specially designed notch or cut at the end of the threads on fire hose couplings. This feature ensures that the threads engage smoothly and align correctly when two hoses are being coupled together, reducing the risk of cross-threading. This easy engagement is crucial in emergency situations where every second counts, as it allows firefighters to connect hose lines quickly and efficiently.

The design of the Higbee cut helps users to find the correct starting point for threading the couplings, thus enhancing the speed and reliability of connection during critical fire suppression operations.
