Absorbs all Directional Movement

General Rubber’s wide arch expansion joints provide superior movement capability in axial compression, axial extension, and lateral deflection, as well as in the angular and torsional direction. This performance cannot be obtained with metallic joints, grooved couplings, or large pipe loops. The low stiffness and deflection forces make designing with General Rubber expansion joints a breeze.

Reduces Noise and Vibration

General Rubber’s expansion joints and flexible connectors effectively dampen and insulate against the transmission of noise and vibration generated by mechanical equipment. This is particularly important in HVAC applications where the disturbing frequency of pipe and fluid-conducting noise can resonate and amplify throughout the building. Metallic joints and grooved couplings do little to reduce noise and vibration.

High Resistance to Shock

The highly compliant and resilient characteristics of General Rubber expansion joints make them ideally suited for earthquake and bomb blast isolation, as well as pressure-surge and water hammer dampening.

Relieves Pipe and Anchor Stress

Thermal movements along with other external forces and displacements, including ground settlement can quickly exceed allowable pipe and anchor stresses. General Rubber expansion joints absorb these stresses and replace them with their own low stiffness (spring rate).

Compensates for Misalignment

It is common in both new construction and replacement applications to encounter pipe misalignment. Minor misalignment can be taken up with standard General Rubber expansion joints, and custom units can be quickly fabricated with large permanent offsets.

Provides Access to Piping and Equipment

Access to piping and equipment can be easily achieved by treating the expansion joint as a removable spool piece. If a self retracting design is needed, General Rubber’s Style 1101DJ dismantling joint can be utilized.
