What kind of fitting is used to transition from a larger pipe to a smaller one?

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

Answer: (C)

The correct choice is a reducer fitting, which is specifically designed to connect pipes of different diameters. This fitting allows for a smooth transition from a larger pipe to a smaller one, facilitating a proper flow of liquids or gases without causing turbulence or significant pressure loss. Reducers come in various shapes, including concentric and eccentric designs, to accommodate different applications based on the orientation of the pipes. While a coupling is used to join two pipes of the same diameter, a tee fitting allows a branch line to be taken off from a main line and does not facilitate reduction in size. An elbow fitting, on the other hand, is used to change the direction of the pipeline but does not serve the purpose of resizing pipes. Thus, the reducer fitting is the only option that directly addresses the requirement to connect a larger pipe to a smaller pipe efficiently.
