What Is The Difference Between Equal Tee And Reducing Tee?

Nov 11, 2025

What is the difference between equal tee and reducing tee?

The core difference between equal tees and reducing tees lies in the diameter relationship between the branch pipe and the main pipe.

Comparison of core differences

 

feature

Equal Tee

Reducing Tee

Core Definition

The nominal diameter of the supervisor (running end) and the branch pipe (branching end) are exactly the same.

The nominal diameter of the branch pipe (branch end) is smaller than that of the main pipe (running end).

Appearance diagram

In a standard "T" shape, with three outlets of the same size.

It forms a "T" shape, but the middle branch pipe is noticeably thinner.

Function and purpose

Equal diversion or merging. Divide the fluid into two equal streams, or merge the two streams evenly.

Non uniform diversion. Separate a smaller tributary from the supervisor.

Fluid influence

When diverting, the flow and pressure of the two branches are basically the same.

When diverting, the flow rate and pressure of the branch pipe will change (usually with an increase in flow rate and a decrease in pressure).

economy

Relatively high (using more materials).

More economical, it can save the cost of branch pipelines when only small flow branches are needed.

How to choose?

1.Ask yourself: Do I need the same amount of traffic on the branch as on the main line?

   Yes:Select equal tee.

   No:Select reducing tee.

2. When purchasing, it is essential to specify the specifications:

    For equal diameter tees, only one caliber needs to be specified

    For reducing tees, it is necessary to specify the diameter of the main pipe and the diameter of the branch pipe

 

Summary

 

       They are like "crossroads" and "exits with auxiliary roads" in the road system, each responsible for different traffic diversion functions.
