Square flange duct connector, ABS plastic, for 100/150 mm hoses What this part does Connects square-flange ventilation outlets to flexible ducting or fan housings while keeping airflow smooth and secure. Designed to reduce internal wind resistance so your ventilation system runs more efficiently and with less turbulence. Key benefits Durable and lightweight: Made from ABS plastic for high hardness and long-lasting performance without adding weight. Chemical resistant: Withstands acids and alkalis for reliable use in kitchens, bathrooms, and other humid or corrosive environments. Secure fit: Tapered design (thinner top, thicker bottom) creates a convenient, stable connection that minimizes movement and leakage. Performance focused: Internal geometry reduces wind resistance to improve airflow and the overall effectiveness of exhaust systems. Compatible sizes: Built for hoses with 100 mm or 150 mm diameter, fitting common exhaust fan and ducting standards. Practical applications Bathroom exhaust fans: Use this connector to join the fan outlet to flexible ducting, improving airflow and reducing backpressure. Inline exhaust fans and duct systems: Ideal for connecting inline fans to square flange fittings when routing air through a ventilation run. Kitchen range hoods and extractor fans: Connect hood outlets to 100/150 mm ducts for dependable ventilation in residential kitchens. Why customers choose it Simple, reliable connection that reduces airflow losses and resists corrosion from humid or greasy environments. Fits common duct diameters and ventilation equipment, making it a practical replacement or upgrade part. Material and size Material: ABS plastic Compatible duct diameters: 100 mm or 150 mm Shape: Square flange duct connector with tapered top and reinforced bottom for secure attachment Installation tip Ensure the hose and flange are clean and aligned before pushing together for the best fit; secure with a clamp or tape as required by your installation.
