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.

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

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.

perfetto e funzionale
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

La disponibilité
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.😥

Riduttore come da aspettative
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.
