Fernco Adaptor Coupling 121-136/110-121mm AC4000

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.

Adaptor Couplings are made from three component parts: one stepped moulded EPDM rubber body with two different diameters on each side and two 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.
