Installation Tips:
- Kair plastic ducting pipe is lightweight & easy to install. You simply push-fit the duct pipe and fittings together. For permanent fixings, you can seal the joints with a method of your choice (Popular options include silicone sealant, solvent cement, or tape).
- Plastic ducting can be carefully cut to the required size using a hacksaw. Offcuts are always useful to keep to hand for joining two male fittings
- Lengths of duct channel can be joined together using a male connector (Part: "DUCVKC355").
- Use round pipe fixing clips to fix ductwork to walls and ceilings and support ducting tube (Part: "DUCVKC354C").
- If your duct run passes through a particularly cold area, we would recommend considering using our pre-insulated ducting to avoid condensation building up within your ductwork. Click here to view our range of pre-insulated plastic ducting.

#1DiameterIs the pipe diameter internal or external? Thanks
Question by Alan, 25-05-2015Diameter - Inner (125mm)
Diameter - Outer (128mm)Replied by i-sells, 26-05-2015#2Size of core drill bitHi, I am DIY installing this through the outer wall to attach to a kitchen extractor. the outer diameter is 128 mm as stated in the technical specs. However most core drill bits near this size only go up to 127 mm. The next common size up is the 152mm. It seems excessive to drill this and then have alot to fill. What are the other options for the hole?
Question by Anthony Li, 27-09-2020Hello Anthony
Thank you for your question. This measurement should be 127mm and will fit through a core drill hole of 127mm.Kind RegardsAnitaReplied by i-sells, 29-09-2020#3120mm?My new Bosch cookerhood extractor has a 120mm diameter outlet. Will this 125mm ducting fit?
Question by Michael Vernoum, 12-10-2021Good morning Michael and thanks for the question.
If the spigot on the cooker hood is 120mm, then you can use the VKC267 125mm ducting, providing you also buy the DOM519 adaptor. That will sit on the end of the duct and slide over the spigot.Kind regards,Marc.Replied by i-sells, 13-10-2021#4125mm to rectangularI have a canopy hood and need to go from round to rectangular on a 90 degree bend as it enters a roof void If I go for a larger size equivalent rectangle flue than 125 will it reduce the efficiency ?
Question by JMES, 16-12-2021Good morning James and thank you for your question.
As long as you convert to a flat channel duct of similar air flow, you should be fine. I would suggest using VKC5606 as your elbow, and then utilising 204x60 ducting with an airbrick to the outside.If you have any further questions, please feel free to call me on 020 8463 9514.Kind regards,Marc.Replied by i-sells, 17-12-2021 -
