Bell Joint Leak Repair Clamp for D.I. Pipes

Product Overview

The bell joint leak repair clamp, also known as ductile iron socket repair clamp, is a high-performance solution specifically engineered for the rapid repair of leaks in the socket and spigot joints of both grey cast iron and ductile iron pipelines. It is the ideal choice for addressing failures in traditional Push-On joints without the need for service interruptions. It is designed specifically to encapsulate the “bell” or “socket” portion of the pipe joint to stop leaks caused by aged gaskets or joint movement.

Made from high-strength ductile iron, it is suitable for high-pressure applications and can be installed as a wrap-around clamp while the pipeline remains in service, minimizing downtime and excavation. A thick fusion-bonded epoxy coating provides excellent corrosion resistance and potable-water safety, while a heavy-duty EPDM or NBR gasket ensures long-term, reliable leak sealing.

The repair clamp is equipped with an integrated vent plug that allows pressure relief during installation, enabling proper seating and tightening under live conditions. After installation, the plug is closed to complete the seal and also serves as a verification point to confirm leak containment before back-filling.
