Which of the following is true regarding a threaded hose coupling?

The concept of a threaded hose coupling involves two distinct ends: the male and the female connectors. The true statement about a threaded hose coupling is that the female end connects to the male end. This design is essential for creating a secure and leak-proof connection between hoses or between hoses and nozzles, which is a crucial aspect of firefighting operations.

In this context, the male end typically has external threads, while the female end has internal threads, allowing them to screw securely together. This specific orientation ensures that water can flow unobstructed from one hose section to another. The significance of this connection is highlighted in practical firefighting scenarios, where a reliable coupling can greatly impact the efficiency of water delivery for combatting fires.

Other options may describe characteristics of hose couplings inaccurately. For example, while it may be true that only one end can swivel in some designs, it's not a definitive standard across all hose types. Furthermore, the idea that swivel ends must be cut to fit does not generally apply to standard threaded couplings, as they are manufactured to precisely match their respective connector types. Similarly, interchanging the ends would compromise the integrity of the connection, since the structural design of male and female ends is vital for proper functionality.
