Kair 150mm female to 100mm male round ducting adaptor.
The 150mm ducting end is a female socket (the same diameter as rigid 150mm ducting pipe). Male fittings such as connectors, bends, and grilles will fit straight into the socket.
If you wish to connect this to Kair 150mm Straight Pipe (Part: "DUCVKC650") you will require a male connector/coupling (Part: "DUCVKC365").
Kair 152mm Flexible Hose (Part: "DUCP0092/152/35") will fit over and require tape or metal hose clip or quick release worm drive clip to seal
100mm ducting end is male and will fit inside Kair 100mm straight ducting (Part: "DUCVKC250") without the need for a connector.

I need to replace the ACM100T unit and wanted to see if I could use the more powerful ACM150T with this adapter to use the existing ducting?
Hello Paul
Thank you for your question. Yes this item can be used but your airflow will be reduced quite a bit as you are going from 6"- 4".
I want to use this to connect 6" flexible bethroom extractor to 4" roof tile outlet will it do it and how best to attach pipe and it to outlet?
Hi Ian
The duct on the extractor is exactly 150 and we need to connect on to 100 flexible ducting. Would this reducer fit.
Hello Steve
Hello, the tracking number for this order isn't available yet even if I made the order about 3 days ago. Can you give some information about the status of the order? Thank you. Best regards, Riccardo.
