Metal Braided Pump Connectors & Control Rods

Pump connectors are designed to absorb vibration and accommodate for misalignment with lateral offset capabilities. The corrugated metal hose only functions to contain the media.  The braid gives pump connectors its pressure capability and therefore the pump connectors ability to carry the system pressure. When the braid is loose or bagged on the assembly it creates a void because the braid is not end loaded.  This is what happens when control rods are used on braided flexible metal hose assemblies. Control rods stop the pump connectors from end loading. When the pump connectors braid fails to end load because of the use of control rods the corrugated metal hose carries the system pressure and it will fail.
