This connector joins two 150mm × 70mm flat rectangular ducting sections together on a straight duct run, extending the run beyond a single pipe length. It is part of the Luxair 5" push-fit airtight ducting system.
Important — Use Pipe Clips Either Side of Each Joint
On longer duct runs of one metre or more, pipe clips must be fitted either side of each connector joint to prevent the ducting from sagging under its own weight. Sagging joints can break the airtight seal and reduce extraction performance. See the 150mm × 70mm flat ducting pipe clips in the Luxair ducting range.
Ducting Size Guide
Selecting the correct ducting diameter for your motor output ensures maximum extraction performance:
Below 450m³/hr → 100mm (4") ducting
450–750m³/hr → 125mm (5") or 150mm (6") ducting
750–2,000m³/hr → 150mm (6") or 200mm (8") ducting
The 5" Push-Fit System
This component is part of the Luxair 125mm (5") push-fit airtight ducting range. The system combines 150mm × 70mm flat rectangular ducting and 125mm round ducting — both formats carry equivalent airflow rates and are fully interchangeable within the system. All components connect by push-fit for a patent-protected airtight seal with no ducting tape, adhesive, or clips required at joints. The full range includes straight pipe sections, bends, elbows, adapters, and wall outlets to complete any standard ducting installation.
