MALONEY SPECIAL ELASTOMERS FULL FACE FLANGE GASKET

Maloney Technical Products recommends the use of Special Elastomer for sealing ductile iron flanged piping for special applications such as; systems designed for transmitting oils, chemicals, high temperature water and air applications. These conditions require elastomers with enhanced performance above those provided by standard SBR gaskets.

Full Faced Style Gasket

● Sizes 4” – 36”, 1/8” Nominal Thickness	● Holes match ANSI A-21.10, A21.15 and B 16.1 Class 125

Flange drilling.

● Rated for a water working pressure of 350psi	● Designed for unique surface of Ductile Iron Flange joints

For 4”-24” and 250psi for 30”-36” and are based
on maximum rating of C110, C111 & C153	● Employs three ring type pieces mold into the gasket that
flange	project beyond both sides of the main surface of the
Gasket to greatly improve sealing and reduces bolt
torque required to seal the joint

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.
