D.I. Compact Repair Clamps for Plastic Piping

Product Overview

Metalsin’s ductile iron compact repair clamp for socket joint plastic piping is the premier solution for addressing leaks in the socket-and-spigot joints of plastic fittings, such as tees and elbows. In many plastic piping systems (including PE, PVC, HDPE, PPR, and uPVC), the complex geometry of these fittings often creates extremely limited installation space, making standard bell joint clamps too bulky to fit. Our specialized compact repair clamp is specifically engineered for these “tight space” challenges, providing a high-strength, wrap-around repair method that stops leaks effectively without the need for pipe cutting or service interruptions.

Illustration: the application of ductile iron compact repair clamps in plastic piping, especially at the socket joint of the elbow or tee.

This compact repair clamp consists of a two-piece ductile iron body, a pair of high-performance rubber gaskets, and robust fasteners. Its streamlined and space-saving design ensures quick, easy installation while delivering a secure and reliable connection in even the most confined areas. Both exterior and interior surfaces of the clamp shall be fusion-bonded-epoxy or liquid epoxy coated in accordance with AWWA C550. Detailed material grades for each component are outlined in the technical table below.
