The Flexible Drain Adaptor Coupling 180-200 mm / 160-180 mm is a versatile drainage fitting designed to join two lengths of underground or surface drainage pipework with different outside diameters, providing a watertight transition between larger (180-200 mm) and smaller (160-180 mm) pipes. Constructed with a flexible EPDM rubber sleeve and stainless-steel clamp bands, this adaptor coupling accommodates minor misalignments and different pipe materials such as plastic, concrete, clay and metal without the need for complex fittings. Ideal for use in private drainage, sewer and groundworks applications, it helps create secure, reliable pipe connections in both horizontal and vertical installations.
