Electrofusion End Cap
Gamson manufactures high-performance Electrofusion End Caps, designed to provide a permanent, high-integrity seal at the termination point of an HDPE pipeline. Unlike mechanical caps or butt-fusion caps, electrofusion end caps are used when space is restricted or when the pipe cannot be moved to fit into a butt-fusion machine. The fitting contains internal resistive heating coils that, when energized, fuse the cap to the outer surface of the pipe, creating a leak-proof, molecular bond.
Key Features
- Internal Heating Element: The resistive wires are precision-positioned to ensure a uniform melt across the entire fusion zone, even on the rounded end of a pipe.
- Compact Termination: Ideal for sealing pipe ends in narrow trenches, manholes, or dead-end service lines where traditional welding is impossible.
- Barcode Controlled: Features an integrated barcode for automatic setting of fusion parameters, ensuring a consistent weld regardless of ambient temperature.
- High Pressure Performance: Typically rated for SDR 11 (PN 16) or SDR 17 (PN 10), making them suitable for the most demanding gas and water utility applications.
- Fusion Indicators: Small pins pop up during the heating cycle, providing a visual confirmation that the fitting has achieved the necessary expansion pressure.

Primary Applications
- Line Termination: Permanently sealing the end of a main distribution line or a service lateral.
- Future Extensions: Capping a line that will be extended in the future. The end cap can later be cut off to allow for further pipe fusion.
- System Pressure Testing: Providing a secure, high-pressure seal for hydrostatic testing of a newly installed network.
- Emergency Sealing: Rapidly closing off a damaged or abandoned section of a gas or water main.
