Round Plastic Ducting 150mm Diameter

Browse our range of 150mm round plastic ducting and fittings, including rigid duct pipes, connectors, bends, dampers, reducers and ventilation grilles.

The range includes components for kitchen, bathroom, utility room and general ventilation systems. From straight lengths of 150mm rigid plastic ducting to fittings for changes in direction, branching and connections to other duct sizes, you'll find the available products below.

150mm Rigid Plastic Ducting & Fittings

Our 150mm plastic ducting range includes rigid round pipes manufactured from lightweight polymer, with a white finish. Straight ducting is supplied in standard 2000mm (2 metre) lengths, alongside matching fittings and accessories.

The range includes components for connecting duct sections, changing direction and joining different duct sizes. Product specifications and connection details are available on the individual product pages.

What You'll Find in the 150mm Ducting Range

Alongside straight 150mm ducting pipes, Ducting Express stocks a selection of matching components:

Pipe connectors: Including standard straight connectors and connectors with dampers.
45° and 90° bends: For changes in direction within a duct run.
T-pieces and Y-pieces: Branch fittings for round plastic ductwork.
Reducers and adapters: Including 150mm to 125mm and 150mm to 100mm reducers.
Round-to-rectangular transformers: For connections between round ducting and rectangular sizes such as 204 × 60mm and 220 × 90mm.
Fixings and terminals: Pipe clips, mounting brackets, external louvres, gravity shutters and ventilation grilles.

150mm Plastic Ducting Connections and Compatibility

When selecting 150mm ducting fittings, it's better to check both the diameter and connection type.

The standard rigid plastic duct pipes have female ends, while many matching bends, reducers and other fittings have male spigots designed to connect directly to the pipe.

A separate 150mm pipe connector is used when joining two straight lengths of rigid plastic ducting. These connectors are also available with an integrated damper.

For connections between different duct diameters, the range includes 150mm to 125mm and 150mm to 100mm reducers. Round-to-rectangular transformers are also available where the ductwork changes between these formats.

If you're connecting to an extractor fan, flexible ducting or another system, check the dimensions and connection type of both components before ordering. Our team can help you identify the relevant fittings if you're unsure.

Frequently Asked Questions

What is 150mm round plastic ducting used for?

150mm round plastic ducting is commonly used as part of domestic and light commercial ventilation systems, including bathroom, kitchen and utility room extraction. The appropriate ducting specification depends on the ventilation equipment and system requirements.

What lengths of 150mm rigid plastic ducting are available?

Our straight 150mm rigid plastic duct pipes are supplied in standard 2000mm (2 metre) lengths. Matching connectors, bends and other fittings are available separately.

How do I connect two lengths of 150mm plastic ducting?

A 150mm rigid plastic pipe connector is designed to join two straight lengths of ducting. Matching bends and other fittings generally connect directly to the appropriate pipe ends without a separate straight connector.

Can 150mm plastic ducting be connected to an extractor fan?

150mm rigid plastic ducting can form part of an extractor fan system where the connection dimensions and product specifications are compatible. Check the fan's outlet diameter and connection type before selecting the ducting and fittings.

Can I connect 150mm ducting to 100mm, 125mm or rectangular ducting?

Yes. The range includes 150mm to 100mm and 150mm to 125mm rigid plastic reducers, along with transformers for connections to rectangular ducting. Check the dimensions of both sides of the connection before ordering.

Can I connect 150mm rigid plastic ducting to flexible ducting?

A connection may be possible using compatible fittings or adapters, depending on the flexible ducting and its connection dimensions. Check the specifications of both products to identify the appropriate components.

What fittings are available for 150mm plastic ducting?

The range includes straight connectors, connectors with dampers, 45° and 90° bends, T-pieces, Y-pieces, reducers, round-to-rectangular transformers, mounting clips, external vents and grilles.
