Stainless Steel Reducer Tee is a type of pipe fitting in which the branch port size is tinier than ports of the run. This category of pipe fitting can also consider size reduction from one of the run ports to the other. For contrasting implementations in various industries, the reducing tees are obtainable in many combinations of sizes and configurations.

Unlike a standard tee fitting where all 3 branches have the same diameter, a reducer tee has at least one branch with different diameter. This allows for the connection of pipes of different sizes.
