Which statement identifies a male coupling on a 5-inch hose?

• A. Male couplings have exposed threads and larger rocker lugs.
• B. Female couplings have exposed threads.
• C. Male couplings have smooth shank.
• D. Female couplings have swivel lugs.

Answer: (A)

Identifying male vs female hose couplings comes down to the external features you can see on the fitting. A male coupling has threads on the outside of the fitting, which you can feel and see, and it also has larger rocker lugs that help lock the connection when mated with a female coupling. This combination—exposed external threads and larger rocker lugs—clearly marks it as male. In contrast, a female coupling would have internal threads, not exposed on the outside, and a different lug profile, so statements claiming exposed threads belong to female couplings or that male couplings are smooth on the shank aren’t correct.
