Abstract
An end seal assembly is mounted in a conduit or feedthrough body with a through bore of stepped diameter between its ends into which a fiber or wire-carrying metal cable extends. An inner end of the cable is stopped against a shoulder in the through bore, with at least one fiber or wire extending from the cable end out through the second end of the seal body. An end seal is seated at the outlet end of the seal body and has a through bore through which the or each fiber extends. The through bore is filled with epoxy material. The end seal is of a material having a coefficient of thermal expansion approximately equal to that of the epoxy material.
