Works great. I wanted to extend the exhaust tube from my tumble dryer. You’ll need an additional clip to fit. Fits the tube perfectly. Quality product.

Brilliant fit
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
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

Fits perfectly for extractors.
We have an ageing 100mm extractor which extends through a very thick stone wall. 100mm used to be pretty common for small kitchens, but seems to be falling out of favour for a more standard 125mm which works better with tubing and cowls which are usually 125mm/150mm. If you need to connect a 100mm extractor/pipe to a 125mm cowl/external pipe you need a reducer/expander/adaptor (depending on your point of view). The machining of the reducer/expander plays very heavily into whether the part works well or just falls apart within hours of fitting. This reducer fits perfectly to both standard pipes that I got from other suppliers, as well as an extending pipe I got from Amazon. It was very satisfying and very easy to push onto the pipes, and the cowl slotted on perfectly without needing adhesive strips and it's been solid as a rock, surviving direct winds at 60+mph living on a hill during a storm. Good little product and cheaper than other options on here.

Overpriced for what it is.
Not cheap for a piece of plastic. But does the job.

Good quality product
Very compact and good quality. Fits snug just as it should so confirms that the product was quality due to being true to size.

il riduttore è un pezzo molto semplice ma trovarlo in giro diventa complicato i negozi non lo tengono e tanto meno le ferramente, qui è diventato tutto semplice e si adatta perfettamente ai tubi da ridurre

On avait pas ce produit en quincaillerie. J avais acheté une hotte et oh non!! Les normes ont changées. La solution était de repercer un mur de 1.5 m en briques ( des heures de travail😣) au dernier moment j ai penser à Amazon et 8.00€ et 1 jour plus tard ma hotte est poser et en état de fonctionnement.😥

Il pezzo è perfettamente in accordo alla descrizione e rispetta le aspettative. Buona sia manifattura che i materiali utilizzati. Lato 125mm il componente ha la dimensione del tubo, quindi per una eventuale connessione ad un tubo occorre prevedere un raccordo.

Ein passgenaues Spritzguss-Teil, recht bruchsicher, flexibel. So wie man das erwartet.
