Protect and hide wires or improve ventilation with premium ducting products from Toolstation. Our range of ducting supplies includes flexible ducting pipes, ventilation ducts and air ducts in various sizes and configurations. Install extractor fan ducting with a PVC flexible duct hose. This lightweight product has an internal steel helix and comes in sizes up to 150mm. We stock several ventilation ducts suitable for extractor fan ducting, including air brick adaptors and self-seal couplers designed to minimise air leakage. Join PVC ducts with duct connectors, including flat channel duct connectors and flat horizontal bend duct connectors. Use a round, flat-channel PVC duct to keep cables out of sight. To complete any installation, fix ventilation ducts to the wall with duct clips. Choose from flat support duct clips and flat-channel duct clips to suit any application.

Ducting Benefits

Rigid and flexible ducting pipes – straight lengths and bendable hose for different layouts
Ventilation trunking and air tube – for supply and extract systems
Ducting fittings – couplers, bends, reducers and clips for secure installations
Insulated ducting options – to reduce condensation and thermal loss
Universal connectors and collars – adapt between different sizes and fan units
Heavy-duty airflow solutions – designed for continuous use in extraction and HVAC

What is ducting used for?

Ducting is piping or trunking that moves air in ventilation, extraction or HVAC systems. It’s used to carry fresh air in or stale, moist or contaminated air out of rooms in homes, kitchens, bathrooms, workshops and commercial spaces.

What types of ducting pipes are available?

Common options include rigid PVC ducting pipes for straight, long runs; flexible ducting that bends around obstacles; and insulated ducting to reduce heat loss or condensation. Each type fits different installation needs.

How do I connect ducting pipes together?

Use duct couplers, clips or clamps to join lengths. For rigid ducting, push-fit connections and trunking fittings make secure joins. Flexible ducting often uses band clamps. Always secure joints to prevent air leaks.

What fittings do I need for a ducting installation?

Typical fittings include bends 45° and 90°, reducers to change diameter, couplers to join pipes, and mounting clips to fix ducting to walls or joists. Choose fittings that match your pipe diameter for the best performance.

How do I reduce noise in a ducting system?

Keep duct runs smooth and avoid sharp bends. Use rigid ducting where possible and add silencers or flexible sections with care. Insulated ducting can also help reduce noise and vibration.

Ducting Sizes and Compatibility

Choosing the correct ducting diameter is essential for efficient airflow. The most common sizes are 100mm (4 inch) for bathroom extractor fans, 125mm (5 inch) and 150mm (6 inch) for kitchen extractors and range hoods. Always match the ducting diameter to your fan outlet to avoid air leaks and reduced performance.
