Combi Flex (6m Length)

Combi flex in 6m lengths, stocked in 16 diameters from 80mm to 500mm. This combination flexible ducting is the practical middle ground of the flex range — more robust than basic foil flex, simpler and lighter than specialist hose — and the 6m length suits real installations, where flexible duct should be used in short sections anyway.

Sizes and fitting

Every common duct diameter is covered: 80, 100, 125, 150, 160, 180, 200, 224, 250, 280, 300, 315, 355, 400, 450 and 500mm, matching fan spigots, spiral duct and grille box connections without adaptors. Cut to length, slide over the spigot and secure with a hose clip; pull each section reasonably taut so the bore stays open and airflow resistance stays low.

Typical uses include fan connections, plenum drops, extract points on light commercial systems and general-purpose flexible runs in domestic ventilation. Stocked sizes ordered by 3pm are despatched for next-day delivery, and lead times for anything non-stocked are shown on the product page before you order.
