Abstract:
1. A shaft plug comprising: an axial shaft member defining a proximal end and a distal end along a longitudinal axis defined by the axial shaft member; a sealing member formed at the distal end of the axial shaft member and extending outwardly at a substantially perpendicular angle relative to the longitudinal axis; and a first internal member, a second internal member, and a third internal member, each of the first, the second, and the third internal members being deformable and having a substantially circular configuration that defines a diameter, each of the first, the second, and the third internal members including a flat surface extending outwardly along the axial shaft member at a substantially perpendicular angle relative to the longitudinal axis of the axial shaft member and a tapered surface that extends from the axial shaft member at a non-perpendicular angle; wherein the diameter of each of the first, the second, and the third internal members decrease with location from the sealing member and the non-perpendicular angle of the tapered surface of each of the first, the second, and the third internal members increases with location from the sealing member; and the diameter of the first internal member is approximately 0.280 inches and the non-perpendicular angle of the first member is approximately 10.8 degrees, the diameter of the second internal member is approximately 0.230 inches and the non-perpendicular angle of the second member is approximately 14.0 degrees, and the diameter of the third internal member is approximately 0.180 inches and the non-perpendicular angle of the third member is approximately 20.0 degrees.
