What type of fitting connects two branch circuits to a single supply line?

• A. Elbow
• B. Coupler
• C. Tee
• D. Reducer

Answer: (C)

In piping and fittings, when you need to split a single supply into two branches (or merge two branches into one line), you use a fitting with three openings arranged in a T shape. This three-port design lets flow come in from one side and be directed into two separate paths, or vice versa. The Tee is specifically built to create that branch point, making it the best choice for connecting two branch circuits to a single supply line.

Other fittings serve different purposes: an elbow only changes direction, a coupler joins two pipes in a straight line, and a reducer adjusts diameter to fit different pipe sizes without creating a branching path.
