Metalsin’s reducer joint repair clamp for plastic piping is a specialized solution designed for sealing leaks at transition points within HDPE, PVC, uPVC, and PPR systems. Reducers are critical components used to connect pipes of different diameters in water supply, irrigation, and industrial networks. Because these transition zones are subject to unique hydraulic stresses, they require a repair solution that can accommodate the specific geometry of the fitting. Metalsin’s clamp provides a secure, precision-fit fix that maintains the integrity of the pipe diameter transition.

The ductile iron reducer-joint repair clamp for plastic piping.
The assembly is constructed from a robust two-piece ductile iron body, high-performance rubber gaskets, high-tensile fasteners, and a malleable iron vent plug. Its specialized “wrap-around” design allows the clamp to fully encapsulate the leaking reducer fitting, enabling a permanent seal to be achieved while the pipeline remains under pressure. This eliminates the need for costly system shutdowns or complex pipe replacements, providing a fast and reliable method for maintaining plastic piping systems with varying diameters.
