Fernco Adaptor Couplings, sometimes referred to as reducer couplings, are designed to connect unadopted (private) drainage pipes with different outside diameters.

Adaptor Couplings are made from three component parts: one stepped moulded EPDM rubber body with two different diameters on each side and two 316-grade stainless steel clamp bands, which when tightened create a secure connection.

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.
