Metalsin’s 90° elbow repair clamp for plastic piping provides a specialized solution for the rapid containment of leaks at 90-degree directional changes in plastic systems. Whether the elbow is joined via socket connection or butt fusion welding, these fittings are critical junctions in PVC, PP, and PE networks. Widely utilized in water supply, chemical processing, and irrigation, our clamps are specifically engineered to accommodate the geometry of the 90° bend, ensuring a secure and permanent fix where standard straight repair clamps cannot be used.

The ductile iron 90° elbow repair clamp for plastic piping.
The assembly is constructed with a high-strength, two-piece ductile iron body, a precision-engineered rubber gasket set, high-tensile fasteners, and a malleable iron vent plug. This “wrap-around” design allows the 90-degree elbow repair clamp to fully encapsulate the leaking elbow, facilitating an immediate repair while the pipeline remains under pressure. By eliminating the need for costly system shutdowns or complex piping re-installations, Metalsin provides a reliable and time-efficient maintenance solution for modern plastic piping infrastructure.
