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.
On the contrary to the straight tee, it is the lateral tee. The straight tee could be a equal tee, also could be a reducing pipe tee (unequal tee).
Officially a straight tee will be indicated by 3 diameters, namely 3 x 3 x 2 (A x B x C). The A & B measure stands for the Nominal Pipe Size of Run-Pipe, C measure stands for Nominal Pipe Size of Outlet.
