Excellent fit. Highly recommend it. Great value for money. ### ⭐⭐⭐⭐⭐ Most useful for use with Portable Air Conditioners! *by B***I on 17 July 2025* I had two issues once it came to connecting my portable AC’s Exhaust Duct to a window with Louvered Air Vent (1) Extending the Exhaust Duct by connecting it to another of similar diameter. (2) Connecting the extension to an Air Vent with an inlet of similar diameter. I tried numerous contraptions and wasted many hours, before I came to this one. And this has been a true life saver. It does both jobs amazingly well. Quality is second to none; as it appears to be robust and esthetically pleasing! Ordering another as a spare and highly recommended! ## Frequently Bought Together - AC Infinity Noise Reduction Clamp 8-Inch, Duct Coupler with Stainless Steel Clamps, Flexible Rubber Coupling for Inline Fans and Carbon Filters in Growing and HVAC - AC Infinity CLOUDLINE S8 PRO, Quiet 8” Inline Duct Fan with 10-Speed Controller, EC-Motor Ventilation Exhaust Fan for Heating Cooling Booster, Grow Tents, Hydroponics - AC Infinity Flexible 8-Inch Aluminum Ducting, Heavy-Duty Four-Layer Protection, 8-Feet Long for Heating Cooling Ventilation and Exhaust --- ## 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.ro/products/500770680-ac-infinity-noise-reduction-clamp-200mm-duct-coupler-with-stainless](https://www.desertcart.ro/products/500770680-ac-infinity-noise-reduction-clamp-200mm-duct-coupler-with-stainless) --- *Product available on Desertcart Romania* *Store origin: RO* *Last updated: 2026-04-22*
