Flanged Fittings Dimensions and Designation of Outlets

Flange Fittings Dimensions

Dimensions for above fittings are given below in Table No. 6-2.
Some of above fittings are not listed in AWWA C110, but do meet applicable requirements of AWWA C110. The largest opening establishes the basic size of a reducing fitting.
The largest opening is named first, except for bull-head tees and for double branch bends where both branches are reducing; in these two cases the largest opening is named last.
In the designation of the openings of reducing fittings, they should be read in the order indicated by the sequence of the numbers 1, 2, 3 and 4 as shown.
In designating the outlets of side outlet reducing fittings, the side outlet is named last, and in the case of a cross, which is not shown, the side outlet is designated by the number 5. In describing tees reducing on the branch only, the first size applies to both outlets on the run. Similarly, for crosses with the same size for both run outlets and the same size for both branch outlets, it is necessary to indicate only two sizes. For example: for an 8 x 6 tee or wye - it is not necessary to show 8 x 8 x 6; for an 8 x 6 cross - it is not necessary to show 8 x 8 x 6 x 6.
*"K" dimensions are shown in Table Nos. 6-8 and 6-9 on the Special Flanged Tees page.

Notes:
*AWWA C110 and C153 do not include data on wyes of any size.
**See footnote to Table No. 6-13.
***For larger branches, use "A" dimensions.
+For these smaller-diameter reducing tees and crosses, the "A" dimension applies as shown in "cut" of standard tee and cross.
++For these smaller-diameter reducing wyes, the "D" and "E" dimensions apply as shown in "cut" of standard wye.
See General Notes.
+++See Table No. 6-13.
§"F" dimensions for 54"-64" reducers vary with diameters of reduction.
§§"H" and "J" dimensions for 54"-64" tees and crosses vary with diameters of reduction.
