●A reducing tee has outlets of different sizes. To make it clear which outlet is which size, manufacturers write their tee dimensions in the format A x B x C; each letter stands for the nominal size of a tee opening.
●A and B are the two in-line openings. In other words, if you held A up to your eye, you could see out of B.
●C is at a right angle to A and B.

●In the first type, A and B are the same size, and C is smaller. Since A and B are equal, this format is easy to understand. An example dimension is 6 in. x 6 in. x 2 in.
●In another type, B and C are the same size, and A is larger. To understand this scheme, remember that the last measurement, C, is always at a right angle to the other two sides.
●Finally, all openings of the tee could be different sizes. Again, you can easily get the right part by remembering that the last measurement, C, is the right-angle outlet, and A and B are interchangeable because tees can be flipped.
