Which type of fitting is used to connect two pipes of different diameters?

• A. Elbow fitting
• B. Tee fitting
• C. Coupling fitting
• D. Reducer fitting

Answer: (D)

The reducer fitting is specifically designed to connect pipes of different diameters, making it the appropriate choice for this question. It allows for a smooth transition between the two sizes, which is crucial for maintaining flow efficiency and reducing turbulence in piping systems. By using a reducer, you can effectively accommodate changes in diameter without sacrificing the integrity or performance of the system. In contrast, the other types of fittings serve different purposes. An elbow fitting is used to change the direction of the piping but does not facilitate a size transition. A tee fitting provides a branch from the main line but is not intended for different diameters. Lastly, a coupling fitting serves to connect two pipes of the same diameter or to extend a single diameter length, rather than connecting different sizes.
