Electrofusion Reducer
The Gamson Electrofusion Reducer is a high-integrity fitting used to connect two HDPE pipes of different diameters. Unlike a butt-fusion reducer, which requires the pipe ends to be melted and pressed together, the electrofusion reducer uses internal resistive heating coils to fuse the fitting to the outer surface of the pipes. This makes it an ideal solution for diameter transitions in tight trenches, repair situations, or when working with pipes that cannot be easily moved.
Key Features
- Integrated Heating Coils: Precision-wound coils are embedded in both ends of the reducer, ensuring a uniform and controlled melt across the fusion zones of both the large and small pipes.
- Concentric Design: Engineered to maintain a centered flow path, minimizing turbulence and ensuring consistent hydraulic performance across the transition.
- Barcode Automated Fusion: Each fitting is equipped with a barcode that stores the specific fusion voltage, time, and cooling period, which is automatically read by the electrofusion processor.
- High-Pressure Safety: Typically manufactured in SDR 11 (PN 16), providing a robust joint that meets or exceeds the pressure rating of the surrounding pipeline.
- Melt Indicators: Small pins on the body of the fitting pop up during the heating cycle, providing visual confirmation that the correct expansion pressure has been reached within the joint.

Primary Applications
- Water Supply Networks: Stepping down from a primary distribution main to a smaller service pipe in municipal grids.
- Gas Distribution: Providing safe, leak-proof diameter transitions in MDPE/HDPE gas networks where fusion integrity is critical.
