Which type of fitting is used to connect two pipes at a 90-degree angle?

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

Answer: (B)

The elbow fitting is specifically designed to connect two pipes at a 90-degree angle, allowing for a change in direction of the piping system. This type of fitting is crucial in plumbing applications where space constraints or routing considerations necessitate a sharp bend without interrupting the flow. Elbow fittings are available in various angles, though the 90-degree version is the most common for connecting pipes at right angles. In plumbing systems, achieving precise angles is vital for maintaining efficient water flow and proper drainage. The elbow fitting's design ensures that the pipes fit together snugly while also allowing for the flow of water or other fluids without obstruction. This functionality is essential to prevent turbulence and reduce the risk of leaks that might occur with improper fittings. Other fittings serve different purposes; for example, coupling fittings are primarily used to connect two straight sections of pipe, and tee fittings are used to create branches in a plumbing system. Trap fittings are specific components used in drainage systems to prevent sewer gases from entering living spaces. Understanding these distinctions helps clarify why the elbow fitting is the correct choice for connecting pipes at a 90-degree angle.
