A tee (also called a pipe tee or tee fitting) is a common pipe fitting with a T‑shaped structure, used to connect three pipe sections in a piping system. It features one main opening and one branch opening, usually perpendicular to each other, allowing fluid to split, merge, or change flow direction.
Tees are widely used in plumbing, HVAC, oil and gas, water supply, firefighting, and industrial process piping. They are manufactured from materials such as carbon steel, stainless steel, cast iron, copper, PVC, and other plastics to suit different pressure, temperature, and medium conditions.
Common types include:
Equal tee: The branch diameter is the same as the main pipe.
Reducing tee: The branch diameter is smaller than the main pipe.
Threaded tee: Connected via internal or external threads.
Butt‑welded tee: Used in high‑pressure industrial pipelines.
Tees provide stable flow distribution, reliable sealing, and easy installation, making them essential components in modern pipeline engineering.
