  • The Wedge Assembly is designed with a Break-Off Torque Control Nut that will only break off in one direction, ensuring proper installation.
  • The Tandem Stargrip® offers a full 5° deflection through 12” size, 3° on 14”-24”, 2° on 30”-36”, 1° on 42”-48” and 1/2° on 54” & 60” which is same as a standard Stargrip®.
  • The Wedge Assembly is designed to fit specific pipe sizes and is field repairable.
  • No special tools are required for installation of the Tandem Stargrip®.
  • Stargrip® may be used on steel pipe of any size. For steel pipe 12” and under a transition gasket is required if the diameter regimen is IPS. For steel pipe 14” and larger, the pipe’s outside diameter must be the same as ductile iron pipe (CIOD diameter regimen). For sizes 3” – 8”, minimum SCH40 steel pipe wall thickness is required. For sizes 10” through 16” the minimum wall thickness must be equal to or greater than PC350 ductile iron pipe. For sizes 18” and above, the minimum wall thickness of the steel pipe must be equal to or greater than PC 250 ductile iron pipe.
