What type of fitting is used to connect two pieces of pipe at an angle?

• A. Coupling
• B. Elbow
• C. Reducer
• D. Union

Answer: (B)

The correct choice is an elbow fitting, which is specifically designed to connect two pieces of pipe at an angle. Elbows are commonly available in various angles, the most standard being 45 degrees and 90 degrees, allowing for the alteration of the direction of the piping system. This flexibility in changing pipe direction is essential in various plumbing and piping applications, as it helps navigate around obstacles and maintain a fluid flow through the system.

Couplings are used to connect two straight segments of pipe in a straight line, while reducers are designed to connect pipes of differing diameters, transitioning from a larger to a smaller pipe. Unions provide a means to connect two pipes that may need to be disassembled for maintenance or repairs but are not specifically intended for angular connections. Therefore, the elbow fitting is the ideal choice for connecting two pipes at an angle, making it an essential component in many piping systems.
