Fernco Flexible Adaptor Coupling (121/137mm - 108/122mm)

Fernco Adaptor Couplings, sometimes referred to as reducer couplings, are designed to connect unadopted drainage pipes with different outside diameters – connecting larger drainage pipes to smaller drainage pipes and vice versa. These simple yet effective connectors can be tightened onto pipes using a nut driver and torque wrench, creating a permanent airtight and watertight seal in just seconds. Fernco Adaptor Couplings are the tried and tested method for connecting unadopted or private drainage systems and with a range developed over 30 years, Fernco has an Adaptor Coupling for almost any pipe configuration. Applications include housing sites, private roads, industrial sites, agriculture land and more.
