Which plumbing fitting is used to connect two pipes at an angle?

The elbow fitting is specifically designed to connect two pipes at an angle, usually either 45 degrees or 90 degrees. This type of fitting is crucial in plumbing systems where a change of direction is required, allowing for the routing of pipes around obstacles or through walls. Elbow fittings are widely used in various installations, including residential and commercial settings, to facilitate smooth transitions in plumbing lines without causing significant flow disruption.

In contrast, the tee fitting is used to connect three pipes, creating a branch off the main line, and is essential for splitting the flow between two directions. The saddle fitting is typically employed to tap into an existing pipe, allowing for connections without cutting the pipe directly. The coupling fitting serves the purpose of joining two straight pieces of pipe end-to-end, ensuring a continuous flow but does not provide for angle adjustments. Therefore, the elbow fitting is the most appropriate choice for connecting pipes at an angle.
