    • APPLICATION: The rigid 90-degree bend offers superior airflow performance to flexible ducting.
    • EASE OF USE: Round ducting fittings have a male spigot and female pipe, ensuring a solid connection.
    • COMPATIBILITY: Round pipe will easily connect to any round fan.
    • AIRFLOW: When using long duct runs, ensure that your fan has the appropriate power to exert the required force.
    • ACCESSORIES: Our 90-degree bend will push fit to a round pipe or flexible hose when used with a hose clip or tape.


    90-degree bends can be used to run your ductwork around obstacles along walls and into ceilings and offers superior performance and durability over flexible alternatives.

    Kair plastic ducting is lightweight, durable and suitable for commercial and domestic use. It is perfectly suited for ducting your tumble dryer, bathroom or kitchen extractor fan, hydroponics, in-line extract fans, or a cooker hood. It can be used as a part of a long ductwork run for a variety of purposes including whole-house ventilation, passive stack vent, positive input, air conditioning, HVAC, and heat recovery systems.

    • Easy to install and durable, just push-fit duct and fittings together.
    • For permanent fixings, seal joints with a method of your choice (Popular options include silicone sealant, solvent cement, or tape.).
    • Will join any female part of the Kair ducting range.
    • Built to last out of high-quality white Polystyrene/Polypropylene plastic Material.
    • Max / Min Temperature: +60c / -15c.
    • Round rigid ducting provides superior airflow performance vs. comparative size rectangular or flexible duct.
    • Suitable to use in compliance with Part F Building Regulations.
    • Airflow performance independently tested by BSRIA or BRE.

    Recommended usage 

    We always recommend to use as few bends as possible in your duct run to reduce any loss of pressure, this also applies when connecting smaller to larger ducting.
    When supplying air through a powerful fan, ensure that the ducting is not too narrow as this could lead to an increase of air noise, damage to the fan and potential vibration.
    Through the use of adapters, multiple connections to all other systems are possible.
    Our system 100 is commonly used in bathrooms or to branch out from larger systems to smaller rooms.

    Alternative Materials:

    Here at, we stock a large range of galvanised products including 90 degree and 45-degree bends. We recommend our ‘safe seal’ galvanised bends, which are available in a huge variety of sizes from 63mm up to 1600mm.

    If your duct run passes through a particularly cold area, we would recommend considering using our pre-insulated ducting to avoid condensation building up within your ductwork. Click here to view our range of pre-insulated plastic ducting.

      This bend has a sharp inner 90 degree angle – a design known to create airflow turbulence. I bought an alternative item (couldnt see one on i-sells) which had a full sweep bend. This although a little larger improves airflow.

      fit perfectly with the 2m straight section of 150mm dia ducting. used to to connect up a cooker hood to the outside wall without converting to stupid square/rectangular ducting, or using naff flexible hose (bad for air flow).
