Coupling 125 mm – the most popular connector
The 125 mm coupling is our most ordered size. With 125 mm being the standard in grow ventilation, this connector joins two Alu-Dec 127 mm ducts quickly and airtight.
Extend, repair or reroute
Need your duct to reach further than a single piece allows? Or has a section been damaged by a sharp bend or wear? The coupling lets you join two pieces without dismantling the whole system. It is also handy when you relocate your setup and the duct needs a different route.
Fitted in a minute
Push each duct end at least 5 cm over the connector. Secure both sides with a 60–135 mm clamp and check for air leaks. Done. The only tool you need is a screwdriver for the clamps.
Order the 125 mm coupling at plantandflower.be – fast delivery across Belgium.
Can I use a coupling to connect an Alu-Dec duct to a Sono-Connect?
Yes. Both duct types have the same inner diameter of 127 mm and slide over the 125 mm connector. This lets you use Sono-Connect for the quiet section and Alu-Dec for the rest of the run.
