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 from 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.

These gaskets were designed specifically for the unique surface of Ductile Iron. Flat rubber gaskets are NOT considered equal in performance and may not provide the sealing capability the project requires. In addition, their use could result in unintended damage to the flanges and threads of the fabricated pipe by applying excess torque to the bolts/flanges in order to seal.
