The 150 to 125 ducting reducer is a concentric reducer. It’s a cone-shaped simple piece of metalwork that plays the role of an adapter that can either decrease or increase the overall diameter of a duct system. Concentric reducers come in different sizes but the duct reducer 150mm to 125mm is one of the most popular available options. In simple terms, the reducer is a fitting that is very popular for use in ventilation systems as a connection between two pipes that have different diameters. They are all male fittings and are fixed into circular spiral ducting.
It’s important to note that certain changes in the diameter can influence the duct system’s airflows. If the air is passed through a reduced area, there is a chance of noise creation and increased resistance.

Concentric reducers differ from eccentric reducers in a few ways. They come in different shapes and a concentric reducer has a centre line straight in the middle of the two diameters. On the other hand, an eccentric reducer comes with a parallel edge to the connecting pipe. Using the 150 to 125 ducting reducer is easy and only takes a few steps.
Using lightweight galvanised steel means that the duct reducer is a long-term product that you can rely on. Our round duct reducers are used in many different types of extraction and ventilation systems and other fields where there is a need for durable and resistant products.

A concentric reducer is a galvanised adapter aimed to change the diameters within a ducting system. Thye can be used to increase or reduce diameters.
This can vary depending on the diameter. If a specific height is required due to limited space, please contact the team so we can get a bespoke product made.
All metal concentric reducers listed on our shop are made out of galvanised steel. However, we are able to provide this in stainless steel. The most common grades of stainless steel are 304 and 316 grade, and these are made to order. Please contact the team to discuss your requirements further.
Yes, depending on how your system has been designed and installed a concentric reducer can affect your airflow and noise levels. Reducing can also create back pressure for your fan.
You would require a female connection piece to connect to another fitting. For fastening without the need for any pre-drilled holes, we advise our customers to use self-drill screws. Once you have decided on a method of fastening the duct work together, you'll need a sealant. We would advise using duct sealant, which is a water-based sealant and will provide a permanent seal whilst withstanding a reasonable amount of vibration. You could also use cloth tape or foil duct tape. Please see our ''How To'' video - How to connect spiral ducting.
