Abstract
A system consisting of a pencil-type sacrificial anode rod and a companion plug for use in, e.g., marine engines, generators, and other machinery or fluid-containing components requiring the presence of sacrificial anodes to prevent galvanic and electrolytic corrosion. The anode rod is securely held in the plug via a push-to-connect mechanism that allows the anode rod to rotate when acted on by a torsional force. This mechanism allows for extraction of the plug through pure tensile forces on the anode rod, thus preventing the breaking of stuck anode rods through torsional forces or stuck anode rods being left behind in engine components due to unthreading of the anode rod from the plug. Electrical continuity between the anode rod and plug is continuously maintained via metal-to-metal contact.
