One Coupling. A Secure Transition.

Flexible coupling geometry allows Fernco to accommodate differences in outside diameter while creating a secure connection between compatible pipe materials.

Stainless steel clamps provide uniform compression around the coupling, while the flexible elastomeric body conforms to the pipe for a dependable seal.

Find the Right Series for the Connection

Fernco Standard Couplings are designed around the outside diameters of the pipe materials being connected. Start with the pipe types on each side of the connection.
