Airtight Self-Seal Ducting 

Please note most of our hoods have a motor outlet of 150mm. You will require a reducer collar to use System125 ducting.  

We highly recommend using the largest possible size ducting on every installation to maximise air flow. 

Please check each product specification guide to determine what size duct you require.

Aluminium Ducting Tape

125 mm Aluminium Semi Rigid Flexible Hose

125mm Aluminium Semi Rigid Hose

This duct extends from 750mm to 1.5m.

Can be bent into shape by hand, and are perfect for runs that require a firm and flexible hose.

Please note this is not part of our self-seal range and will not fit directly on to 125mm adapter bends.

Single layer aluminium flexible duct with a 4mm corrugation depth to allow the duct to be compressed for transportation. Stated diameters refer to inner bore size. 

This hose is part of our 5 Inch Push Fit range, commonly referred to as 5 inch ducting, due to the round pipe being 125mm / 5" wide. This system includes both 150mm x 70mm flat ducting and 125mm round ducting as they both have similar airflow rates. We supply adapters should you need to switch between these sizes:

Round to Flat Adapter 

Round to Flat Elbow

This is part number 2a from the quick link chart.
