## Features

- This male-fit coupler connects two Ø 6" (150 mm) round ducting pipes in a straight line, ensuring a secure and smooth alignment. The backflow damper opens and closes automatically.
- Crafted from durable ABS plastic, this material offers high strength, excellent toughness, and ease of processing. It's environmentally friendly and non-toxic, making it a safe choice for both residential and commercial ducting applications, including tumble dryer vents, extractor fans, ventilation systems, and cooker hoods.
- Designed to fit most extractor fans, bathroom fans, kitchen exhaust fans, in-line extract fans, cooker hoods, and various heating or cooling ducts. Just slide the flange into your round ducts and secure it with duct tape, clamps, or sealant for a quick and straightforward installation.
- Duct draft stopper prevent cold air or wind from entering the ventilation pipe. In this case, the flap is installed in such a way that the flap leaves only open into the outgoing air direction. This means that no cold air / wind or smell can penetrate the ventilation pipe from the outside.
- The backflow Preventer valve is installed by pushing it into the ventilation pipe as far as it will go. The position of the spring should be horizontal when the flap is installed horizontally so that it can be opened and closed optimally. This also applies to the vertical installation.
