A reliable 125 mm → 100 mm duct reducer is essential when your kitchen hood, tumble dryer or air‑conditioning unit needs a smooth transition between different hose sizes. This universal connector snaps onto a 5‑inch (125 mm) duct and tapers down to a 4‑inch (100 mm) outlet, or works in reverse to enlarge a smaller vent—perfect for retrofits, repairs or new installations.
Key benefits

– All‑metal construction – sturdy steel resists corrosion and holds up to the heat and moisture typical of kitchen and laundry environments.
– Easy fit – pre‑drilled holes align with standard 5‑inch and 4‑inch duct clamps, so you can secure it in minutes without special tools.
