Fernco SC425 Shear-Banded Coupling 400 to 425 mm

The Fernco SC425 Shear-Banded Coupling is a professional-grade flexible joint engineered to join drainage pipes with outside diameters between 400 mm and 425 mm. Built as part of Ferncos shear-banded range, this coupling blends a flexible EPDM rubber sleeve with heavy-duty shear-banded stainless steel clamps delivering outstanding clamp strength, high torque retention and secure sealing under real-world conditions.

Shear Banded Drain Coupling Data Sheet

Shear-banded clamps are engineered for superior grip compared with standard bands, helping ensure the coupling maintains an airtight and watertight joint even when exposed to vibration, ground movement or changing temperatures. The flexible body allows for seamless transitions between PVC, clay, concrete and cast iron pipe materials, and compensates for minor misalignment without compromising performance.

Installation is quick and efficient with common hand tools, reducing labour time and site disruption. With excellent resistance to mechanical load and environmental factors, the SC425 is an excellent choice for commercial, industrial and large infrastructure drainage systems.
