PVC Grey Flex

PVC grey flexible ducting — the economical general-purpose flex, stocked in 14 diameters from 80mm to 500mm. Grey PVC flex is a staple of ventilation and extract installation: easy to handle, easy to cut, and priced for jobs where a straightforward flexible connection is all that is required.

General-purpose flexible duct

The PVC grey flex range covers 80, 100, 125, 150, 160, 180, 200, 250, 300, 315, 355, 400, 450 and 500mm — matching fan spigots, spiral duct fittings and grille box necks across the common ventilation sizes, so it drops onto existing systems without adaptors. Use it for fan connections, extract runs in commercial and light industrial settings, fume cupboard tails and the flexible last metre of any ducted system where a simple ambient-temperature connection is all the job asks for.

Like all flexible ducting it performs best short and taut: let rigid spiral duct do the distance and use the flex where movement, vibration or alignment demand it.

Knowing PVC’s limits

PVC grey flex is an ambient-temperature product — for hot air duties choose high-temp silicone flex instead, and for dust and shaving extraction the abrasion-resistant anti-static PU flex is the right tool. Within its lane, though, PVC is hard to beat on value: general room ventilation, extract connections and fume cupboard tails rarely need more. Cut it cleanly to length, push fully onto the spigot and secure with a hose clip at every joint.
