Abstract
An end fitting attachable to an end of a sucker rod includes a generally cylindrical body having a receptacle portion, a coupling portion, and a longitudinal axis. The receptacle portion has a receptacle extending inwardly from an open end surface of the body along the longitudinal axis for receiving the end of the sucker rod therein, with the receptacle having at least one annular cavity. The coupling portion extends from a coupling end surface of the body opposite the open end surface and is configured to connect the end fitting to another component. The coupling portion may further include an area of predictive failure. A diagnostic sensor may be included in a cavity of the end fitting.
