The Nylon XT60 Connectors Male/Female are excellent W.S. Deans T-connector replacements. They are made from high-temp Nylon and gold plated spring 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 are not cheaply copied XT60 plugs. These are original Nylon XT60 plugs can handle over 60A current for extended periods without exceeding 80ºC thanks to their better contact surface area. The plug is also less likely to deform or melt in comparison to copied non-Nylon XT60 plugs.
