Abstract
A method of sealing includes positioning graphite within a cavity defined by walls of a body, shifting the body along a tapered surface of a first structure, expanding the body through an interaction with the tapered surface, engaging at least one second structure with the walls, expanding the graphite, compressing the graphite against the at least one second structure, and sealing the graphite to the at least one second structure and the body.
