8 inch insulated flexible duct helps reduce heat loss and control condensation for cleaner, more efficient airflow in HVAC, dryer exhaust, and ventilation setups. Built with a triple-layer jacket—aluminum/PET outer layers plus fiberglass insulation around a spiral steel-wire core—it flexes around tight spaces without collapsing. Includes two clamps for a fast, secure connection on common duct ports and fan collars.

Designed for demanding ductwork where space is tight and insulation matters, this insulated duct supports temperature control, dehumidification, and ventilation in home HVAC systems, fresh-air setups, workshops, and greenhouse tent ventilation. The coil structure helps the hose hold shape while staying flexible for tricky turns and equipment clearances. Measure your port diameter and planned route, then secure both ends with the included clamps for a tight seal.
