Abstract
A seal assembly (10) includes a seal ring shell (12) and an insert (14). The seal ring shell includes an inside diameter surface, and may also include a seal ring shell tapered portion that extends radially inwardly from the inside diameter surface. The insert includes an upper surface, and may also include an insert tapered portion. With embodiments, a portion of the upper surface of the insert contacts or operatively engages the inside diameter surface of the seal ring shell, and a portion of the insert tapered portion engages the seal ring shell tapered portion such that the seal ring shell tapered portion may impede movement of the insert in a direction substantially along the inside diameter surface (e.g., in an axial direction).
