Hon&Guan Ducting Reducer 150mm to 100mm, 6 to 4 inch Extractor Fan Reducer Circular Reducing Joint Duct Pipe Connector Adaptor

Perfect, reduced my 6 inch duct down to the 4 inch outlet in the wall. Top seller.

Does exactly perfect connection for electic fan in toilet to existing exterior pipe

A very solid and well made product, giving a smooth transition from 150 to 100mm. The extra long tails make fitting any flexible ducting quite easy, as there is plenty of room for a cable tie. No problem in fitting the 150mm end onto a Neff hood as the inside diameter is just over 151mm - in fact I added a couple of screws to stop the adaptor being blown off when the fan is on full power. A bit expensive, otherwise it would have been the full 5 stars.

Bought this reducer to use between a cooker hood and the pre installed (directly cemented in the wall‽) duct. I must say that the reducer is a Solid piece of plastic construction and push fit perfectly onto the cooker hood (Smeg Victoria) and inside the duct. Functionally very good as well, I’ve checked for leaks around the edge and nothing! I personally think the price is reasonable considering the faff I had in local shops trying to get hold of one. From my experience the reducer doesn’t interfere, positively or negatively with the noise level.

Fits as required and competitively priced. Delivered next day.

Did the job it was bought for very quick delivery

This did the job of connecting the insulated ducting onto the tile vent hose in the loft. Sturdy enough but by god it's WELL OVERPRICED for just a bit of plastic pipe!! Will buy again but it's not like I will be getting a few of these to keep on the van at this (over)price!!!

As an electrician / domestic ventilation installer I frequently have to overcome the fact that idiot builders have installed 110mm soil pipe as a “duct” instead of 100mm ventilation ducting. This item converts it properly. Super tight fit. The 110mm side fits tightly around the outside of the 110mm pipe (the main part of the pipe not the female end) and the 100mm side fits internally on 100mm ducting or flexible ducting. It’s well made and not at all flimsy like others. A little pricey compared to buying from some wholesalers but you pay for the convenience and delivery. If you were to buy just the adapter with delivery from elsewhere it would be this much anyway and take longer to arrive. Will buy again
