FAQ: What are the recommended uses for this flexible duct? -This duct is designed for applications such as kitchen vent hoods, dryers, heating ducts, HVAC air lines, indoor gardens, growth tents and bathroom exhausts. Can this duct be used as a portable air conditioning hose? -Not a good choice for portable AC applications. We recommend using a plastic duct for the exhaust of alternating current, as the plastic does not accumulate or dissipate heat until it reaches the window exhaust. Can this hose be used as a portable vacuum cleaner / leaf nozzle hose? -No, this hose is made of a double layer of film and a layer of black PVC plastic and is designed to transfer air. Debris transferred through the vacuum will pierce the flexible ducts. Package includes: >1 x PVC flexible ducts. >2 x steel clamps.
