This adaptor coupling is designed for joining drainage pipes of different sizes, specifically connecting pipes with outside diameters between 110-125mm and 100-115mm. The black, smooth-finished coupling is often used in unadopted or private drainage systems where pipe sizes and materials vary.
Typically installed with a nut driver and torque wrench, the coupling provides a straightforward method for joining pipes on sites such as housing developments, private roads, and agricultural land. It is commonly chosen for its adaptability and straightforward installation process in civil and drainage works.
