Flexible couplings incorporate a rubber body with stainless bands to enable the fitting to compress down onto different sizes and types of pipe.
As the steel band is tightened (like a jubilee clip), the EDPM material from which the coupler is made compressed uniformly around the pipe, forming an airtight and watertight seal. The clips are made from stainless steel which means that they are impervious to rust.
The adaptor couplings consist of a stepped moulded sleeve that can connect to pipes of various diameters at each end.
One end of this stepped adaptor can be connected to a pipe with an outside diameter of between 170mm and 192mm, while the other end can be connected to a pipe with an outside diameter of between 144mm and 160mm.
These adaptors are ideal for joining pipes of different outside diamaters without the use of a bush, or for connecting PVC drainage pipe to other drainage materials such as clay, salt glaze, supersleve, asbestos cement and pitch fibre.
There are many types of drainage materials that are still in use from previous generations, and connecting on to them can sometimes prove problematic. Flexible couplings remove the need for a multitude of different size adaptors by their adjustable nature.
The steel bands are adjusted and tightened using a screwdriver.
