It is designed to connect 4" to 3" dia hose. ## Frequently Bought Together - POWERTEC 70145 4-Inch to 3-Inch Reducer - Daisypower Dryer Vent Window Kit, Adjustable Window Vent Kit with Outdoor Dryer Vent Cover,4 Inch Hood for Exhaust Ventilation - VIVOSUN D4 4 Inch 195 CFM Inline Duct Ventilation Fan HVAC Vent Blower for Hydroponics Grow Tent --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/59053357-powertec70145-4-inch-to-3-inch-reducer](https://www.desertcart.pl/products/59053357-powertec70145-4-inch-to-3-inch-reducer) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-05-25*
