The Luxair 100mm round rigid ducting pipe
provides a clean, permanent, airtight ventilation run for cooker hoods rated below 450 m³/hr. Each length is 1 metre of solid, rigid fire-resistant and mould-resistant polymer pipe — the core building block of a rigid round ducting installation that connects your cooker hood to an external wall vent or ceiling outlet. Self-sealing push fit ends mean individual lengths connect to each other and to Luxair's full range of 100mm elbows, connectors, and adaptor collars.
Rigid vs Flexible — Why Rigid Ducting Performs Better
Most DIY cooker hood installations use flexible aluminium hose because it's easier to route. Rigid ducting outperforms flexible hose in every measurable way — lower airflow resistance means your motor works less hard to move the same volume of air, less noise because there are no corrugations for airflow to vibrate against, and longer lifespan because rigid polymer doesn't degrade, collapse, or develop leaks over time the way flexible hose can. For any permanent kitchen installation, rigid round ducting is the professional choice.
Self-Sealing Push Fit — No Tape at Any Rigid Joint
Each 1-metre length has push fit ends that connect to Luxair's 100mm elbow connectors, straight connector collars, and adaptor fittings with an airtight seal on contact — no ducting tape, sealant, or clips required at any rigid-to-rigid joint. Ducting tape is only needed when transitioning from rigid pipe to flexible aluminium or plastic flexible hose. For a full rigid run from hood to external wall, no tape is needed at any point.
Build Your Full Ducting Run
A complete 100mm rigid ducting run typically combines several lengths of this 1-metre pipe with the appropriate connectors from Luxair's 100mm range. Common components needed alongside this pipe include 90° elbow connectors for right-angle turns, 45° elbow connectors for gentler direction changes, straight connector collars for joining two pipe lengths end-to-end, round-to-flat adaptors for transitioning to flat rectangular ducting where space is tight, and an external wall vent or grille to terminate the run outside the property. All are available in Luxair's 100mm ducting collection.
All the components you need to complete your 100mm ducting run are available as related products at the bottom of this page — add elbows, connector collars, flat adaptors, flexible hose, and external wall vents to your basket in a single visit without searching for each part separately.
Is 100mm the Right Size for Your Hood?
100mm (4") ducting suits cooker hood motors rated below 450 m³/hr. Using undersized ducting on a higher-rated motor restricts airflow, reduces extraction performance, and increases motor noise. Luxair's size guide by motor rating:
- Below 450 m³/hr → 100mm (4") ducting
- 450–750 m³/hr → 125mm (5") or 150mm (6") ducting
- 750–2000 m³/hr → 150mm (6") or 200mm (8") ducting
Luxair stocks 1-metre rigid round ducting pipe in all four standard sizes — 100mm, 125mm, 150mm, and 200mm — all available in the ducting section.
