Bolt holes match ANSI A21.10, A21.15 AND B16.1. All gaskets meet the requirements shown in the appendices of AWWA C110, C111 and C115.

 

Prior to assembly, make sure the flanges are free of sand, grit, grease or other foreign material.

 

Hand tighten all bolts and check for alignment. Use a crisscross pattern to tighten the bolts, starting with the top bolt then the bottom bolt 180° from the top bolt, then 90° to the left and tighten that bolt, then 180° to the right across form it then one bolt to the right and repeat the crisscrossing for the remainder of the bolts. Flange bolts must be evenly torqued in stages to provide proper sealing.
