What connects a section of piping and other components of piping systems?

The correct answer is fittings, as they play a crucial role in connecting various sections of piping and other components within a piping system. Fittings come in various forms, such as elbows, tees, reducers, and couplings, allowing for direction changes, size adjustments, and easy assembly of piping systems. They facilitate the establishment of a continuous flow path and are integral in ensuring the system operates efficiently, without leaks or interruptions.

While valves are essential components that control the flow within a piping system, their primary function is to open and close the flow rather than connect different sections. Similarly, flanges serve as convenient connection points between piping segments or between pipes and equipment, but they require additional components, such as gaskets and bolts, to create a secure connection. Brackets, on the other hand, are used for support and stabilization, not for connecting piping sections. Thus, fittings are specifically designed for the purpose of connecting, distinguishing them as the most accurate choice in this context.
