ABSTRACT:
A fluid-tight sealing apparatus with a protective liner for sealing a pair of tubes having high temperature and pressure fluid flowing therethrough. The apparatus comprises an inner tubular surface coupled to the first tube and a sealing assembly coupled to the second tube and receivable in the inner tubular surface in an interference fit. The sealing assembly comprises a metallic, annular resilient sealing member and a rigid protective liner located inside and substantially concentric to the sealing member but spaced inwardly therefrom for limiting radially inward deformation of the sealing member to prevent plastic deformation thereof.
