ABSTRACT:
A fluid pressure seal comprising the combination of a metallic sleeve-like member having one or more annular grooves around its outer periphery and two or more annular grooves on its inner surface, the grooves located to establish an accordion-like area in the member intermediate its ends, and flexible non-metallic sealing material within and filling the grooves. When the seal is installed between two adjacent metallic surfaces, such as around a valve stem and within a chamber in a valve bonnet, axial compression of the seal causes radial expansion of the accordion-like area into fluid-tight contact with those surfaces to produce a metal-to-metal static and dynamic seal therebetween.
