The Tee fitting is specifically designed to combine or split fluid flow within a piping system. Its unique shape allows it to connect three sections of pipe, forming a ‘T’ where one pipe runs straight, and the other branches off at a right angle. This feature is essential in plumbing and fluid delivery systems, enabling the distribution of liquids or gases from a single source to multiple destinations or the merging of flows from various sources into a single line.

In contrast, an Elbow fitting is primarily used to change the direction of fluid flow, either at a 90-degree or other angles, without splitting or combining the flow. A Union fitting serves the purpose of connecting two sections of pipe together while allowing for easy disassembly, but it does not engage in the combining or splitting of flow. Lastly, a Coupling also connects two pieces of pipe but similarly does not have the capacity to split or combine flows. Understanding these distinctions clarifies why the Tee fitting is the correct choice for the function described in the question.
