Fernco AC Adaptor Coupling
Fernco adaptor 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.
