Kair Plastic Ducting Pipe 100mm - 4 inch / 1 Metre Long Length - Rigid Straight Duct Channel

Plastic tube 150mm is diameter. Worked well with the europlast 150mm fan.

Good quality compatible with all fittings I used

Good product, reasonable price

I recently purchased the Rigid Straight Duct Channel and I have been impressed with it. I had previously been struggling with flimsy tubing that was difficult to install in the wall of my loft. However, the Rigid Straight Duct slipped right into the outside vent with ease and made a secure connection. I then simply cable tied the flexible ducting to the other side and it worked like a charm!The quality of the duct channel is impressive. It is incredibly sturdy and durable, making it a reliable choice for any ventilation system. The installation process was straightforward and hassle-free, which is always a plus.Overall, I highly recommend the Rigid Straight Duct Channel to anyone who needs a reliable and easy-to-install ventilation solution. Its sturdy construction and ease of use make it a worthwhile investment.

happy with item.Used for extractor fan in garage.did the job over drilled at 172mm and filled in with exp foamhappy with duct and was long enough to bridge normal cavity wall

It's a piece of plastic tube whats there to say about it

125mm (internal diameter) round plastic duct from Kair. Good durable product and a snug taper push-fit onto standard “125mm” plastic fittings such as elbow or connector.The slight taper on these fitting ends grip the duct securely meaning that additional duct tape might not be required.But in an inaccessible invisible place where leaking condensation drips might cause damage I usually add a wrap of tape anyway, just in case age and de-plasticizing or vibration might slacken the grip.This is ideal for use inside a building and protected from the UV of bright sunshine.

The size was a bit longer than needed so I have spares
