Notes:
*AWWA C153 configurations with shorter center-to-socket dimensions, etc. may be furnished in some cases in the 18"-20" size range. Check AMERICAN if dimensions are critical.
**18" and larger Fastite and 16" and larger Flex-Ring and Lok-Ring 90° Bends may be furnished with Fastite Plain Ends, Flex-Ring Ends, or Lok-Ring Ends. See Table No. 4-2.
+ Higher pressure ratings are available on special applications. Pressure ratings may be limited below the values shown by the pressure rating of the pipe to which fitting is attached, or the restrained joint used.
Based on performance testing per AWWA C153, AMERICAN can rate 30"-48" C153 bends 350 psi. Check AMERICAN.
See General Notes.
++ 16" Flex-Ring fittings may have greater "T" dimensions than those shown.
^ Fastite fittings with these weights have different dimensions than are shown in this table. Contact AMERICAN when dimensions are critical.
^^ 18"-48" Fastite and Flex-Ring bends can have the same appearance (both have basic cross-section of top middle "cut").
