Fernco SC470 Shear-Banded Coupling 445 to 470 mm

The Fernco SC470 Shear-Banded Coupling is a heavy-duty flexible connector designed for drainage pipework with outside diameters between 445 mm and 470 mm. Built for large-scale commercial, industrial and infrastructure drainage systems, this coupling combines a durable EPDM rubber sleeve with high-strength shear-banded stainless steel clamps to deliver exceptional sealing integrity and long-term performance.

Shear Banded Drain Coupling Data Sheet

The shear-banded clamp design provides superior torque retention and enhanced gripping force compared with standard clamp bands, helping ensure a secure airtight and watertight joint even under vibration, ground movement and temperature fluctuation. The flexible rubber body compensates for slight pipe misalignment and allows smooth transitions between PVC, clay, concrete and cast iron pipe materials.

Installation is quick and tool-friendly, reducing labour time while delivering a professional, reliable finish. With excellent resistance to corrosion and environmental stress, the SC470 is ideal for demanding drainage installations where reliability is critical.
