Full details
The B&Q Multi-Layered Flexible Duct Hose is an ideal solution for HVAC professionals and homeowners seeking a durable, high-performance ventilation component for heating, air conditioning, and general air exchange systems. Its primary benefit is a reinforced, non-flammable structure that prevents condensation buildup, ensuring cleaner and more efficient airflow; however, users should note that the 3-meter length requires precise cutting for installations requiring shorter runs.

FAQs
Can this duct be used for dryer venting?
While the hose is non-flammable, it is primarily designed for HVAC and ventilation; always check local building codes regarding specific materials required for dryer exhaust.
What is the diameter of this hose?
This model has a standard diameter of 125mm.
Is the hose suitable for outdoor use?
Yes, the PVC cladding provides UV resistance, making it suitable for protected outdoor installations.
How do I cut the duct to length?
Use a sharp utility knife for the foil/PVC layers and heavy-duty wire cutters to cut through the internal steel coil.
Does this hose come with mounting clamps?
No, mounting clamps must be purchased separately based on the specific requirements of your mounting surface.
Can I join two lengths together?
Yes, you can join two lengths using a 125mm rigid duct connector and secure both ends with duct tape or clamps.
Troubleshooting
Airflow feels restricted or weak
Check the hose for sharp bends or kinks caused by improper routing and ensure the duct is pulled sufficiently taut.
Hose is sagging between support points
Use additional mounting straps or hangers to support the weight of the ducting over longer spans.
Noise during system operation
Ensure that the hose is properly secured at both ends with clamps, as vibrations often originate from loose connections.
Pros and Cons
Pros
- Resistant to UV light and chemical exposure
- Reinforced structure prevents kinking and shape loss
- Anti-condensation design improves hygiene
- Non-flammable material increases installation safety
Cons
- Fixed 3-meter length may result in excess material for small runs
- Installation requires specific clamps which are not included
- Rigidity of the steel coil can make tight-radius bending challenging
Setup, Compatibility & Care
To install, measure the required distance between your ventilation ports and trim the duct using heavy-duty wire cutters to handle the steel coil. Secure each end of the 125mm hose to your connection points using appropriate worm-gear clamps or metallic duct tape to ensure an airtight seal. Avoid installing near sharp metal edges that could puncture the PVC cladding. For cleaning, simply wipe the exterior with a soft cloth dampened with mild soap; avoid using abrasive scrubbers that might degrade the PVC coating over time. Regularly inspect the hose for any signs of physical damage or loose connections to ensure the system remains sealed and efficient.
