Secure, waterproof wall flange for ventilation hose — ABS construction, available in 100 mm or 150 mm Key benefits Prevents air and water leaks: creates a tight, waterproof connection between the wall and ventilation hose to stop drafts and moisture infiltration. Improves ventilation performance: a sealed connection reduces air loss and helps the ventilation system run more efficiently. Fast, simple installation: designed for straightforward wall mounting to save time and labor during installation or replacement. Durable and reliable: made from ABS material for long-lasting, water-resistant performance in domestic and light commercial environments. What it does This ventilation hose adapter (wall flange) provides a secure, watertight interface between a wall opening and round ventilation or exhaust ducting. It is suitable for connecting kitchen hoods, bathroom extractor fans, and other exhaust systems to exterior walls or duct runs while minimizing air leakage and moisture entry. Compatibility and sizes Available in two standard diameters: 100 mm or 150 mm. Compatible with a range of round exhaust and ventilation hoses and ducts that match these nominal sizes. Offers flexibility to fit common residential and small commercial ventilation setups. Easy wall mounting Designed for quick, straightforward installation on typical wall surfaces. Mounting saves installation time and avoids complicated fittings; ideal for retrofit or new installs. Typical applications Kitchen range hood exhaust through an exterior wall: provides a sealed transition from hood duct to outside venting. Bathroom extractor fan outlet: prevents moisture and odors from leaking into the wall cavity while maintaining airflow. Laundry or utility room vents and small HVAC exhaust runs where a watertight wall flange is required.
