The Flexseal Multibush combines three standard bushes into one product by allowing the user to fold the product into different thicknesses. This is ideal when it’s unclear which pipe materials need to be connected as it will connect pipes of any standard wall thickness. For example a 100mm Multibush can act as a 3mm, a 6mm or a 9mm bush and connect a clay to PVC, clay to cast iron, ductile iron to twinwall and many more.

WIS 4-41-01 guidelines specify the use of a shear-banded coupling when connecting sewer pipes, which can present difficulties when connecting pipes of different ODs.

Using a Flexseal Multibush and a Standard Coupling avoids the need to stock different couplings for different connections, and so provides a cost efficient, time efficient and stock efficient pipe connection. No matter which pipe materials you’re working with, the Flexseal Multibush will guarantee a secure connection.
