Fernco SC445 Shear-Banded Coupling 420 to 445 mm

The Fernco SC445 Shear-Banded Coupling is a heavy-duty flexible connector engineered to join drainage pipework with outside diameters between 420 mm and 445 mm. As part of Ferncos shear-banded range, this coupling combines a resilient EPDM rubber sleeve with high-performance shear-banded stainless steel clamps to deliver superior clamp force, excellent sealing performance and long-term durability even under demanding conditions.

Shear Banded Drain Coupling Data Sheet

Shear-banded clamps are designed for enhanced torque retention and gripping strength compared with standard clamp bands, helping ensure the coupling remains airtight and watertight under vibration, ground movement and temperature changes. The flexible rubber body compensates for slight pipe misalignment and supports smooth transitions between PVC, clay, concrete and cast iron pipe materials. This makes the SC445 ideal for large commercial, industrial and infrastructure drainage systems where performance counts.

Installation is quick and tool-friendly, helping reduce labour time on site while delivering professional results. With strong resistance to corrosion and environmental stress, the SC445 provides dependable performance for demanding drainage applications.
