Single Axial (UNRESTRAINED)
Expansion joints designed to absorb axial movement from thermal expansion and contraction of pipework.
Double Axial (UNRESTRAINED)
Expansion joints with two sets of convolutions, capable of absorbing axial and lateral movement.
Single Tied (RESTRAINED)
Expansion joints with tie bars to restrain the pressure thrust and permit limited lateral deflection.
Double Tied (RESTRAINED)
Two sets of convolutions with tie bars to restrain the pressure thrust and permit limited lateral deflection.
Single Hinge (RESTRAINED)
Expansion joints that permit angular rotation in a single plane, restraining thrust from internal pressure.
Double Hinge (RESTRAINED)
Two hinge type expansion joints in one unit absorbing lateral deflection in a single plane.
Single Sphere Rubber Pump Flexible (ANTI-VIBRATION)
Single sphere rubber unit designed to absorb vibration and noise caused by plants such as pumps, chillers, etc.
Single Sphere Rubber Bellows (HIGH TEMPERATURE)
Single sphere rubber unit designed to compensate for high temperatures, vibration and noise caused by plants.
Multi-ply Pumpflex Unit (ANTI-VIBRATION)
Multi-ply rubber unit is the most effective for absorbing vibrations and small axial movements.
