Made from high-temp Nylon and gold plated bullet connectors, both included in the injection mold at the time when forming the connector. The XT60 ensures a solid high-amp connection, perfect for applications up to and beyond 65A constant. These original Nylon XT60 plugs can handle 60A current for extended periods without exceeding 80DegC thanks to their better contact surface area. The plug is also less likely to deform or melt. 12" Black and 12" Red 5mm High Quality Heat Shrink Tubing 2:1 included.
