Production Process

Double Sphere Rubber Expansion Joint

The Double Cablesphere is the result of adding the Metraflex innovation of factory-installed control cable to the Doublesphere.  The control cables restrain the hydrostatic end load so there is no need for control rods.  The Double Cablesphere handles more movement than a Cablesphere and provides all the value. The Double Cablesphere’s cables limit the extension of the joint, so it is primarily a pump or equipment connector.  It can also be used as an expansion joint if EJMA guidelines are followed. Control rods are not needed.
