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.

Abstract: A sucker rod assembly comprising, an end fitting including a body with a rod receptacle cavity extending axially, a generally cylindrical sucker rod received within the rod receptacle cavity defining one or more annuli, a quantity of initially flowable adhesive bonded to the rod and disposed in the one or more annuli forming at least one wedge, a surface on the rod is spaced from a surface on the end fitting defining a void space therebetween, a blocking element is disposed between the surface on the end fitting and the surface on the rod, filling the void space. There is disclosed a blocking element in the form of a void filling incompressible material interposed between the end of the rod and the bottom end of the rod receptacle cavity.
