Fabricated Tees & Crosses
The “A” dimension on a TEE is based upon the “D” dimension, or O.D. plus a factor listed in the AWWA spec. Reducing Tees and Crosses are also available. The “A” dimension for the outlet is based on the O.D. of the run and the “f” factor for the outlet size. The “A” dimension for the run becomes the “B” dimension and is based upon the O.D. of the outlet and the “f” factor for the run. With a reducing tee, the “A” dimension for the outlet would change to “B” and be shorter.
