Top seller. ### ⭐⭐⭐⭐⭐ Great product *by S***L on 8 May 2026* Does exactly perfect connection for electic fan in toilet to existing exterior pipe ### ⭐⭐⭐⭐ Good quality *by P***L on 23 September 2021* 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. ## Frequently Bought Together - Hon&Guan Ducting Reducer 150mm to 100mm, 6 to 4 inch Extractor Fan Reducer Circular Reducing Joint Duct Pipe Connector Adaptor - Kair Plastic Ducting Pipe 100mm - 350mm Short Length - Rigid Straight Duct Channel - Kair Round Connector 100mm - 4 inch to Connect Duct Pipe or Flexible Ducting Hose --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sn/products/51174458-ducting-reducer-150mm-to-100mm-6-to-4-inch-extractor](https://www.desertcart.sn/products/51174458-ducting-reducer-150mm-to-100mm-6-to-4-inch-extractor) --- *Product available on Desertcart Senegal* *Store origin: SN* *Last updated: 2026-06-18*
