PVC Grey Flex

Grey PVC flexible ducting stocked in 14 diameters: 80, 100, 125, 150, 160, 180, 200, 250, 300, 315, 355, 400, 450 and 500mm. This is the budget-friendly flexible duct for general ventilation work — light, flexible, simple to cut to length and quick to fit over any round spigot.

Where PVC flex works best

Fan connections, extract points, fume cupboard tails, plenum drops and general room ventilation all suit PVC grey flex, indoors and in ambient-temperature duties. The wide size run means one product family covers everything from a 80mm valve tail to a 500mm connection on commercial plant, and every diameter lines up with our galvanised spiral ducting so mixed rigid/flexible systems assemble without adaptors.

Fit each end over its spigot, clamp with a hose clip, and keep the run short and free of kinks. For warm or hot air choose silicone flex; for dust extraction use anti-static PU flex. Stocked sizes ordered by 3pm are despatched for next-day delivery, with free UK mainland delivery over £400 ex VAT.
