## Questions & Answers

**Q: Can you tell me the length please?**
A: The length / height is 70mm

**Q: how do i stick this to my air con? its 125mm connector on the air con but the window and pipe is 150mm and threaded, but cant find a threaded version!**
A: I don’t see anything in the Kair range that solves your problem. The 150 -125mm reducer is just slip-on and it worked fine in my situation. Does the Air-con manufacturer have a fixing to take you from thread to smooth or technical department you can approach for advice? If all else fails You could try to make a connector from flexible hose and fasten with glue and large jubilee clips. Sorry I can’t be more help.

**Q: How is this fixed to the other pipe? Does it need a jubilee clip and if so, is it sufficent to fix it in place?**
A: This is more designed to reduce the size of the fitting on a fan and isn't designed to put two pipes together.

 With that in mind, to make it work for that, both of your pipes would need to be an adequate size to fit over both sizes of the reducer and a jubilee clip would suffice to hold it in place.

**Q: My bathroom extractor fan is 100mm but the ducting is 110mm. This reducer seems to be the ideal solution to remove the gap - is it?**
A: It is, although this is designed to fit ducting so you may need a short sleeve of 100mm ducting between the reducer and your fan.

### ⭐⭐⭐⭐⭐ Brilliant fit
*by A***R on 27 October 2025*

Quality products fitted perfectly reducing 6” kitchen extractor to 5” vent pipe. Price and delivery very good what’s not to like and why it’s not rated higher is beyond me .

### ⭐⭐⭐⭐ Does not fit a 100mm outer pipe but good quality
*by A***R on 30 June 2024*

Crazy I know but I had a tumble dryer with an outlet of 100 mm and the smaller dryer needed to be 80mm so I ordered this to do the job trouble is it fitted the 80mm new dryer but obviously the 100 mm outer duct was 100mm so it didn’t fit we had to get a piece of plastic bigger and tape it up! My fault but it was good quality plastic
