Recommended usage
We always recommend to use as few bends as possible in your duct run to reduce any loss of pressure, this also applies when connecting smaller to larger ducting.
When supplying air through a powerful fan, ensure that the ducting is not too narrow as this could lead to an increase of air noise, damage to the fan and potential vibration.
Through the use of adapters, multiple connections to all other systems are possible.Alternative Sizes & Angles:
Kair round 90-degree plastic bends are available in 100mm, 125mm, and 150mm versions.
Kair round 45-degree plastic bends are available in 100mm, 125mm, and 150mm versions.

This bend has a sharp inner 90 degree angle - a design known to create airflow turbulence. I bought an alternative item (couldn't see one on i-sells) which had a full sweep bend. This although a little larger improves airflow. -

#1125mm 90degree round bendDo you do a male to female 125mm bend
Question by Phil, 19-01-2016Hello Phil,
I am not aware of an off-the-shelf plastic 125mm male to 125mm female 90 degree bend but you can use a cut down length of plastic pipe or a galvanised metal female sleeve connector (Part: "GALMF-125") to achieve a similar result.
Kind regards,

Question by Andrew, 18-02-2020Hello Andrew
Thank you for your question. This item is made from Polypropylene so a duct sealant would need to be used product code QS46199 and the outside joint sealed with duct tape.Kind RegardsAnitaReplied by i-sells, 19-02-2020#6Full bore bend?Does item QS263 feature a full bore bend - or does the bore reduce?
Question by Seb, 09-09-2021Hi Sebastian. The 90 degree bend is 125mm both sides.
If you need to reduce, you would need to use a piece of 125mm ducting and a reducer.Kind regards,Marc.Replied by i-sells, 09-09-2021 -
