This adaptor coupling is intended for joining drainage pipes of differing diameters, specifically ranging from 144–160mm to 110–122mm. It is suitable for use with unadopted (private) drainage systems, providing a means to connect larger pipes to smaller ones where required on site.
Commonly used during installation, repair, or modification of drainage runs, this coupling accommodates pipes made from various materials. The fitting can be secured quickly using basic hand tools, offering a practical solution where different pipe sizes need to be joined efficiently.
