Product name: Long K-style Wall Flange Vent Hose Adapter Key benefits Watertight, secure connection: Made from durable ABS, the adapter creates a waterproof seal between the wall and the ventilation outlet to prevent air and moisture leaks. Improves ventilation efficiency: By eliminating leakage at the wall penetration, it reduces energy loss and improves the overall performance of exhaust fans and duct systems. Quick, low-effort installation: Designed for straightforward wall mounting to save time during setup and minimize installation errors. What it does Provides a stable, long K-style connection between a duct or flexible hose and the wall flange. Seals the interface to stop drafts and moisture ingress, protecting the building fabric and maintaining designed airflow. Aligns and supports the duct run to reduce strain and noise from loose connections. Key attributes Material: High-quality ABS for impact resistance, dimensional stability, and corrosion-free performance. Sizes: Available in 100 mm or 150 mm diameters to match common duct and vent sizes. Compatibility: Fits a variety of ducts and vent openings (100 mm or 150 mm specification), offering flexibility for retrofit or new installations. Mounting: Wall-flange design intended for simple, secure wall installation. How it solves common problems Stops air leaks that reduce exhaust efficiency and allow odors or damp air to re-enter the space. Prevents water and condensation from entering the wall cavity at the vent penetration. Provides a durable connection that reduces the need for frequent re-sealing or replacement. Typical applications Kitchen range hood exhaust: Creates a watertight, secure link between the hood duct and the outside wall outlet to preserve extraction performance and prevent backflow. Bathroom extractor fans: Seals and supports the fan duct through the external wall to stop moisture and odors from escaping into the building fabric. Utility or laundry room vents: Connects dryer or utility exhaust ducts to the wall flange for reliable, maintenance-free operation. Installation notes Choose the correct diameter (100 mm or 150 mm) to match your duct run and vent opening. Wall-mount using appropriate fasteners and sealant for your wall material to ensure a watertight finish. Inspect that the duct/hose is fully engaged with the adapter to prevent gaps and ensure optimal airflow. What makes it stand out Simple, purpose-built design using ABS for long-lasting, corrosion-free service. Available in two common sizes for flexibility across residential ventilation needs. Designed specifically to address leak, moisture, and alignment issues at the wall penetration, improving system reliability and indoor air quality.
