Abstract

A microseal for a metal bead seal joint includes a substantially horizontal surface, first and second substantially vertical surfaces disposed on opposite ends of the substantially horizontal surface, and a contoured surface operatively configured to adhere to a portion of a metal bead. The contoured surface may be disposed opposite the substantially horizontal surface and may be integral to the first and second substantially vertical surfaces. The substantially horizontal surface may be operatively configured to substantially maintain its horizontal surface orientation in both a compression state and a non-compression state.
