What piping component is a short length of pipe with threads on both ends used to join two female-threaded fittings?

• A. Nipple
• B. Coupling
• C. Elbow
• D. Tee

Answer: (A)

In piping connections, a short length of pipe with threads on both ends used to join two female-threaded fittings is called a nipple. Its defining feature is male threads on each end, which screw into the internal threads of the female fittings to make a straight connection. This is different from an elbow or a tee, which change the direction or create a branch, and from a coupling, which typically joins pipes using female-threaded ends rather than male on both ends. The nipple provides the compact straight-link solution between two female fittings.
