Limitlink™ Restraint Cables
These cables prevent over extension of the expansion joint. They provide maximum flexibility in stress-sensitive piping systems.
Antisquirm® T-Bands™
The Antisquirm Flexijoint greatly improves the lateral stability of the bellows in High Pressure services. Restraints on the T-Bands™ guide the bellows during axial movement to eliminate squirming of the convolutions.
