Long ABS duct/vent connector that creates a secure, waterproof join between the wall and the ventilation slot. Designed to stop air leakage, simplify installation, and improve overall system efficiency. Key benefits Prevents air leakage: The watertight ABS construction seals the connection between wall and vent slot to eliminate drafts and reduce energy loss. Fast, reliable installation: Wall-mount design saves time and effort during setup and provides a stable, professional connection. Improves ventilation performance: A secure joint keeps airflow directed through the ductwork, improving fan efficiency and indoor air circulation. Flexible compatibility: Available in 100 mm or 150 mm sizes to match common duct and vent diameters. Product highlights Material: Durable ABS for a waterproof, stable connection. Sizes: Choose 100 mm or 150 mm to fit standard duct/vent openings. Application: Specifically designed for ventilation systems and duct fan hoses. Function: Acts as a wall flange/vent connector to join the duct hose to the wall opening with a long channel adapter for a neat, sealed fit. Typical use scenarios Kitchen extractor hood: Connect the range hood duct to the external vent through the wall with a sealed, splash-resistant joint. Bathroom ventilation: Create a secure, waterproof connection for the exhaust fan duct to prevent moisture-related leaks and maintain airflow. Utility or laundry room ventilation: Attach inline fan hoses to wall vents to ensure consistent exhaust performance and reduce air escape. Installation and compatibility Wall-mount design for straightforward attachment to standard wall openings. Available in two sizes (100 mm, 150 mm) to fit common duct and ventilation slot dimensions; select the size that matches your existing ducting. Use with channel/duct fan hoses and standard ventilation slots; intended for ventilation system applications in residential or light commercial settings. What it solves Stops air and moisture escape at the wall-vent interface. Reduces pressure loss and improves fan/duct efficiency. Simplifies the connection process for a clean, durable installation. Specifications Material: ABS Sizes: 100 mm or 150 mm Application: Ventilation systems, duct fan hoses, wall-to-vent connections Buy if you need a simple, durable, and waterproof wall-to-duct connector that fits common 100 mm or 150 mm ventilation systems and reduces air leakage while making installation easier.
