How can you identify a female coupling on a 5-inch hose?

• A. Exposed threads and larger rocker lugs
• B. Smooth shank, swivel and smaller rocker lugs
• C. Smooth shank and larger lugs
• D. Rugged end cap

Answer: (B)

Identifying a female coupling on a 5-inch hose hinges on recognizing a smooth shank without any external threads, along with a swivel and smaller rocker lugs. The smooth shank means there’s no threaded end to engage with a male nut, which is a hallmark of a female connection. The swivel feature allows the coupling to rotate independently of the hose, helping prevent kinking during handling. The smaller rocker lugs fit with the opposite end’s lugs, allowing a secure connection once aligned. In contrast, exposed threads indicate a male or threaded end, and a rugged end cap isn’t a coupling at all. So the combination of a smooth, non-threaded shank, a swivel, and smaller rocker lugs is the clear indicator of a female five-inch hose coupling.
