What is the term used for the top part of a fire hydrant?

The correct term for the top part of a fire hydrant is "bonnet." The bonnet serves several important functions in the overall design of the hydrant. It is the covering that protects the internal components of the hydrant from debris and weather elements, ensuring that the hydrant remains operational when needed. Additionally, the bonnet often contains the outlet ports where hoses can be connected for firefighting operations.

Understanding this terminology helps firefighters and emergency personnel communicate effectively about equipment and ensures that everyone is on the same page when discussing fire hydrants in training, planning, or real-life situations. This knowledge is essential for efficient firefighting efforts, particularly in emergencies where rapid deployment of resources is critical.
