Wall-mounted flange adapter for ventilation ducts, made from durable ABS. Creates a secure, waterproof connection between the wall and the ventilation duct to reduce air leakage and improve system efficiency. Key benefits Reliable, waterproof seal: ABS construction and a flanged design prevent air and moisture escape at the wall penetration, protecting the building envelope and reducing drafts. Improved ventilation performance: By eliminating leaks at the wall junction, the adapter helps maintain designed airflow and increases overall system efficiency. Quick, low-effort installation: Designed for straightforward wall mounting so installation takes less time and requires minimal tools. Versatile compatibility: Available in 100 mm and 150 mm sizes to fit common duct and vent dimensions. Features and specifications Material: ABS plastic for impact resistance and long-term durability. Sizes: Select 100 mm or 150 mm to match your existing ductwork or vent openings. Function: Flange-style wall connector that links the building wall to the ventilation duct while providing a watertight and airtight joint. Application: Specifically intended for ventilation systems—suitable for range hoods, exhaust fans, and ducted ventilation setups. Why customers choose this adapter Stops unwanted air and moisture transfer at the wall, reducing energy loss and the risk of condensation damage. Saves installation time with a simple wall-mount design that aligns with standard duct sizes. Fits common ventilation needs without the need for custom parts or additional sealing hardware in most installations. Typical use scenarios Kitchen range hood: Connects the hood duct to the exterior wall, ensuring exhaust air is directed outside without leakage or water ingress. Bathroom exhaust fan: Provides a watertight transition from the fan duct to the exterior vent opening, reducing humidity-related issues in wall cavities. General ventilation or utility rooms: Used where reliable wall-to-duct connections are required for laundry rooms, utility spaces, or ducted HVAC runs. Installation notes Choose the correct size (100 mm or 150 mm) to match your duct or vent. Mount the flange to the wall opening and secure per local building codes; additional sealant can be used if required by your installation. Inspect and tighten connections to maintain the waterproof and airtight seal over time. Specifications summary Material: ABS Sizes available: 100 mm, 150 mm Intended use: Wall-to-duct flange adapter for ventilation systems (kitchens, bathrooms, other ventilation applications)
