Airtight Self-Seal Ducting 

Please note most of our hoods have a motor outlet of 150mm. You will require a reducer collar to use System100 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

100mm Round to Flat 120mm x 60mm Horizontal Connector

100mm Round to 100mm x 60mm Flat Connector

This connector is used to connect a 120mm x 60mm flat ducting pipe to either 100mm round ducting pipe or the 100mm flexi aluminium tube. It can be used in either vertical or flat position.

This adapter has a push fit air tight seal and requires no ducting tape.

This is part number 9 from the ducting chart below.

This clip is part of our System100 range, commonly referred to as 4 inch ducting due to the round pipe being 100mm / 4" wide. This system includes both 100mm x 60mm rectangular ducting and 100mm round ducting as they both have similar airflow rates. We supply adapters should you need to switch between these sizes:
