Fernco Adaptor Couplings 35mm to 420mm

Fernco Adaptor Couplings join drain and soil pipes of different materials and outside diameters, such as clay to plastic or cast iron to PVCu.

Each coupling has two size ranges, large end first, both as pipe outside diameter in mm. Offset versions (marked Offset) line up the bottom of the two pipes for a smoother flow between sizes. Measure the outside of both pipes and fit the smallest pipe first. More flexible couplings, caps and adaptors are in our flexible rubber connectors range.

Common Questions

Which one joins 4 inch clay to 110mm plastic? Measure the clay pipe: Fernco list AC1602 for 100mm Supersleve or clay to 110mm PVCu.

What does Offset mean? The pipes sit level at the bottom, which helps the flow through the joint.
