How do I attach it to the hose?** A: It all depends upon pipe diameters - will your two pipes fit either inside one of the fixed rings. If flat plastic pipes you can glue them on or in. If ribbed flexo hose you can simply use a zip tie with hose fitted to outside **Q: Can this withstand heat to use with tumble dryer hose (4 and half inch) to extractor hole in wall (3 and half inch)?** A: yes its fine I use it also on exhaust of my air conditioner and that is pretty hot **Q: What is the height of the converter? I am fitting a new Cooker hood in a cupboard and the gap between the outlet of the hood and the pipe is 4-5cm.** A: I can’t remember to be honest but that’s probably the height of the first two bottom sections. It doesn’t matter cos the pipe will fit to whichever section it lands on the rest will go inside the pipe or you can break off the sections not required from the top either way. ## Frequently Bought Together - Universal reducer for ventilation systems 80/150 mm diameter, reducer connector tube 80, 100, 120, 125, 150 mm diameter transition ventilation round tube RDRC. - CIARRA Integrated Cooker Hood 52cm CBCS5913A Stainless Steel Built in Extractor Hood LED Light 3 Speeds Undercabinet Extractor Fan - Ciarra CBCF005 Activated Carbon Filter for Inegrated Cooker Hood CBCS5913A, CBCB5913A, CBCS5913D(Pack of 2) --- ## 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.com.sa/products/56684284-universal-reducer-for-ventilation-systems-80-150-mm-diameter-reducer](https://www.desertcart.com.sa/products/56684284-universal-reducer-for-ventilation-systems-80-150-mm-diameter-reducer) --- *Product available on Desertcart Saudi Arabia* *Store origin: SA* *Last updated: 2026-05-10*
