Duct fan hose adapter — waterproof ABS connector for wall-mounted vents Key benefits Creates a secure, waterproof connection between the wall and the vent opening to prevent air leakage and drafts. Improves the overall efficiency of your ventilation system by maintaining proper airflow and reducing loss. Easy, time-saving wall installation that requires minimal tools and effort. Main features Material: Durable ABS for long-lasting, water-resistant performance. Function: Connects duct or fan hose to a wall vent slot, sealing the joint to stop air escape. Sizes: Available in 100 mm or 150 mm diameters to match common duct and vent sizes. Compatibility: Designed to work with various ducts and vent slots used in residential and light commercial ventilation systems. Why you need it Stops inefficient airflow and reduces energy loss caused by poor or leaky duct connections. Provides a reliable, waterproof seal where the duct meets the wall, protecting the wall cavity from moisture and air infiltration. Simplifies installation and retrofit projects with a plug-and-play connector that fits standard duct sizes. Installation and performance notes Designed for quick wall mounting; mounting hardware and exact method depend on your wall type and local installation practice. Choose the 100 mm or 150 mm size to match your duct or vent opening for best fit and sealing performance. ABS construction resists common indoor moisture and provides a stable, long-term connection. Typical applications Kitchen exhaust systems: connect range hood ducting through an exterior wall to maintain efficient smoke and odor removal. Bathroom extractor fans: seal the wall penetration to prevent moisture and odor leaks while keeping extractor performance consistent. Laundry rooms or utility vents: create a secure passage for dryer vents or general ventilation ducts to protect wall cavities and improve airflow. What makes it stand out Combines a watertight seal and sturdy ABS construction with straightforward wall mounting and two standard size options for wide compatibility — a practical solution for improving ventilation efficiency without complex modifications.
