It’s always best to use the official Separett pipework where possible because you are assured of a perfect fit and long-term performance. However, there may be situations where this isn’t possible, such as getting the vent pipe around awkward objects or reducing the number of ninety-degree bends.

Flexible pipe (commonly sold as dust extraction pipework) is available in 50mm (for the Tiny) and 75mm (for the Villa) diameters.
