Flexible PVC duct hose 3 m
Product description
A flexible PVC duct hose can make a tricky installation noticeably easier, especially when you need to route warm air around obstacles or through tight spaces. This Kair flexible hose is designed for ducting runs with 150 mm systems and offers a practical way to connect extractor fans, cooker hoods, tumble dryers, and air conditioners using warmer air exhaust setups. If you want something that bends to your route rather than forcing rigid plastic ducting into place, this flexible approach is worth considering 😊.
The essentials

This Kair PVC flexible hose is built for ducting applications where flexibility matters more than a completely straight run. With a listed 152 to 154 mm external diameter, it is intended to fit over 150 mm, or 6 inch, ducting systems, so you can keep the connection aligned with the typical duct size used for warm air extraction. The hose comes in a 3 metre length, giving you a useful amount of reach for common domestic installations and adjustments.


Flexible ducting is also handy when there are bends, awkward corners, or limited clearance around appliances. Instead of fighting with rigid sections, you can guide the hose into position around the obstacles you actually have on the job. It is commonly used with warm air exhaust systems such as cooker hoods, extractor fans, tumble dryers, and air conditioning units that discharge warm air.

Worth noting that flexible ducting is often treated as female, meaning duct fittings like bends and reducers are generally male and slip inside the hose. That installation style can make assembly straightforward, but it also means the hose and fittings need to be compatible with that slip fit arrangement. 🙂
Key features



The main advantage of this hose is its ability to run ducting around obstacles where rigid plastic ducting may be unsuitable. PVC flexibility helps you shape the airflow route to the space available, which can reduce the hassle of repeatedly adjusting rigid lengths. For many households, that practical installability is what makes the difference between a neat, functional setup and one that is hard to complete.
The listed fit is based on diameter compatibility, with an external diameter range of 152 to 154 mm and suitability for 150 mm, or 6 inch, ducting systems. That size guidance matters when planning connections to ensure the hose can slide onto the duct route as intended. It also comes as a 3 metre flexible run, which can help you avoid unnecessary joining or excess strain on connections.

When attaching the hose to a spigot or male fitting, you have several practical options. Quick release worm clips, metal hose clips, silicone, or duct tape are mentioned as suitable methods for securing the connection. Which method you choose can depend on how accessible the joint is and how permanent you want the attachment to be.


You may want to check the exact connection style at the appliance or fan spigot before committing. It’s not uncommon for installations to vary in how fittings are presented, and this hose is described around a female ducting slip fit approach. 🤝

Who it’s for
It’s a good fit if you’re installing or replacing ductwork for warm air extraction and you need flexibility to work around real world obstacles 🏠. You’ll likely appreciate it if you’re dealing with tight spaces where rigid ducting can be difficult to align neatly. It also suits common household ventilation uses like extractor fans, cooker hoods, tumble dryers, and air conditioner warm air exhaust.
It may not suit you if your layout requires rigid ducting for every section and you prefer fully fixed straight routing. It can also be less convenient if your existing fittings are not compatible with the described female ducting slip fit style, or if you are unsure how the spigot and joints are meant to connect.
