A Reducing Tee is also called “unequal tee“,which means the tee branch pipe diameter is not same with the run pipe of the tee.Commonly, in a reducing tee,the branch pipe diameter is smaller than the running pipe.But there are also some project the branch pipe diameter of the tee is bigger than the run pipe,it means the branch is the inlet of the flow .
A straight tee means a tee of pipe fitting which the branch outlet has a 90 degree direction turning from the main pipe of the tee.Commonly people consider the straight tee as the equal tee,it is a mistake.Equal tee means a same sizes of the branch and main pipe of a tee.Straight tee means it has a side port at right angle to the run.
