Fernco Adaptor Coupling 180-200/160-180mm AC6000

Adaptor Couplings for Drainage Pipes

Adaptor couplings, also known as reducer couplings, are designed to connect unadopted drainage pipes with differing outside diameters. These couplings are commonly used to transition between larger and smaller diameter pipes, providing a simple and effective solution for varied pipe sizes.

Each adaptor coupling consists of three components: a stepped moulded EPDM rubber body with two different diameters, and two stainless steel clamp bands. When tightened, the bands compress the rubber body around the pipe ends to create a secure and durable connection.

Installation is quick and efficient using a nut driver and torque wrench, delivering a permanent, airtight, and watertight seal in a matter of seconds—ideal for both new installations and repair work.
