Sign up for PATIKIL 8" To 4" Duct Reducer Connector – PP Fire-Resistant Ventilation Adapter For Bathroom Fans, Range Hoods, Dust Collectors
Need to connect two different-sized ventilation ducts?
This PATIKIL reducer connector does the job perfectly.
It steps down from a 200mm (about 8-inch) opening to a 110mm (about 4.3-inch) one, so you can hook up bathroom fans, range hoods, or dust collectors to your existing ductwork.
It's made from durable polypropylene (PP) material that's lightweight, waterproof, moisture-resistant, and fire-resistant—so it's safe and long-lasting.
It can handle temperatures from -10°C to 70°C, which covers most indoor and light industrial applications.
Installation is super easy: just slide each end over the corresponding duct and secure it.
The reducer design keeps airflow smooth and efficient, even with different pipe sizes.
Great for homes, offices, kitchens, or factories.
