Replacement lower duct hose for Shark NV340 Vacuum Cleaners. 
Please note this is not the main hose, but the small hose that connects the head to main body of the vacuum.
Lost suction to the head of your Shark NV340 lift off vacuum cleaner, but not to the hose? Chances are the lower duct hose needs replacing, these are quite a common replacement and fairly easy to change.
