  • COMPATIBILITY – Male fit coupler is designed for standard round ventilation ducts used in bathroom fans, inline extractor fans, hydroponics setups, and general air movement systems.
  • DURABLE PLASTIC CONSTRUCTION – Air Duct Connector is made from lightweight, corrosion-resistant PVC that performs reliably in temperatures from 23°F to 140°F, making it suitable for everyday ventilation use.
  • BUILT-IN BACKDRAFT PROTECTION – Designed to allow airflow in one direction only, helping prevent reverse air movement, drafts, and unwanted odors entering the duct system.
  • QUIET & LOW-RESISTANCE OPERATION – Balanced lightweight flap opens easily under airflow and closes gently when the fan stops, maintaining smooth, efficient ventilation without mechanical noise.
  • EASY INSERT INSTALLATION – Simple push-in design allows quick installation inside ducting without complex tools, suitable for residential and commercial ventilation setups.
