Shear Banded Drain Coupling Data Sheet

Shear-banded clamp technology enhances torque retention and gripping force compared with standard couplings, ensuring the joint remains airtight and watertight even when subjected to vibration, movement or temperature variation. The flexible rubber body compensates for slight pipe misalignment and supports smooth transitions between PVC, clay, concrete and cast iron pipe materials.

Installation is fast and tool-friendly, reducing labour time on large projects while maintaining professional-grade results. With excellent resistance to corrosion, mechanical load and environmental stress, the SC320 is ideal for commercial, industrial and infrastructure drainage systems where reliability is critical.
