The 60cm long Maxiflex Flexible Pipe is a fully flexible spiral hose for the ventilation of soil and waste piping and mechanical ventilation systems, such as the Nature Vent Slate Vent. The pipe is made from a double coated polyamide fabric with welded steel wire, with connection sleeves at both ends. It is also available with a reducer fitted at the lower end with a 70/100m spigot The small spiral spacing makes Maxiflex highly versatile for bending through difficult double bends. The multiple slits in the connect or makes it adaptable to small differences in pipe sizes. The pipes should always be installed in such a way as to avoid the possibility of any condensate collecting inside it.
