Abstract: A corrosion fuse is a device connected with a compressed air tank in order to provide a predictive indication of corrosive activity occurring within the compressed air tank. The corrosion fuse includes a corrosion detector established as a thin-walled metal tube closed on one end and open to an environment outside the compressed air tank on the other end. The joining of the corrosion fuse with the compressed air tank is enabled by the connection of a plug with a fitting (i.e., flange). The plug connects to the open end of the corrosion detector and with the flange. The flange is connected to the compressed air tank about a tank receiver disposed on the compressed air tank. The tank receiver allows the corrosion detector, connected with the plug, to at least partially extend inside the compressed air tank, when the plug is connected with the flange.
