SPECIAL ELASTOMERS MECHANICAL JOINT GASKET

The Mechanical Joint gasket is designed to be used in cast iron mechanical joint fittings for cast iron size pipe (ductile iron and C-900 PVC). Mechanical Joint gaskets made of SBR are usually used for water and domestic sewage service. MJ gaskets made from SBR are used for air or liquid temperatures up to 150°F. For applications with temperatures above 150°F, or for other special service applications, consult the table below or call your S&B Technical Products Customer Service Representative.

Available in the following compounds:

200°F150°F
Fresh water, salt water, sanitary sewage, storm water, greases

• Sizes 4″-24″
• Standard SBR made per ANSI/AWWA C111/A-21.11
• Rated for a water working pressure of the pipe.

Call S&B Technical Product Customer Service Representative with the project specifications for recommendation on best compound to use for a special application, current lead times and for pricing. S&B maintains inventory on many of the sizes and special compounds.

SPECIAL ELASTOMERS MECHANICAL JOINT X IPS TRANSITION GASKET

The MJ X IPS Transition gasket is designed to be used in cast iron mechanical joint fittings for adapting to PVC or steel pipe (IPS dimensions).  These gaskets made of SBR are usually used for water and domestic sewage service.  MJ X IPS Transition gaskets made from SBR are used for air or liquid temperatures up to 150°F.  For applications with temperatures above 150°F, or for other special service applications, consult the table below or call your S&B Technical Products Customer Service Representative.

Available in the following compounds:

• Sizes 4″-16″
• Standard SBR made per ANSI/AWWA C111/A-21.11
• When properly installed these gaskets can be used at working pressures up to 350 psi or the pressure rating of the pipe, whichever is less.

Ring Flange Gasket

S&B Technical Products recommends the use of S&B Special Elastomer Ring Flange Gasket for sealing ductile iron flanged pipe when special applications such as systems designed for transmitting oils and chemicals, high temperature water and air applications require elastomers with enhanced performance criteria above SBR gaskets.

Available in the following compounds:

• Sizes 4” – 36”, 1/8” Nominal Thickness
• Rated for a water working pressure of 350psi For 4”-24” and 250psi for 30”-36”
• Compatible with flanges confirming to ANSI/AWWA C-115/A21.15, ANSI/AWWA C110/A21.10, ASME B16.1 class 125, ANSI/AWWA C207 class B, D, E and F, and ANSIB16.5 in sizes 4”-24”
• Designed for unique surface of Ductile Iron Flange joints
• Employs three ring type pieces molded into the gasket that project beyond both sides of the main surface of the gasket to greatly improve sealing and reduces bolt torque required to seal the joint

TECHNICAL DATA S&B SPECIAL ELASTOMERS RING FLANGE GASKET

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.
