A coupling apparatus that may have a first component having a first sealing surface and a second component having a second sealing surface. The first and second sealing surfaces are in facing relationship with one another when the first and second components are coupled together. One of the first and second sealing surfaces has a metallic film layer that transforms into a liquefied metal layer when the metallic film layer is exposed to a temperature that exceeds a melting temperature of a metal from which the metallic film layer is formed. The liquefied metal layer forms a seal between the sealing surfaces.

1. A coupling apparatus comprising: a first tubular component having a first sealing surface;a second tubular component having a second sealing surface, said first and second sealing surfaces being in facing relationship with one another when said first and second components are coupled together;one
1. A coupling apparatus comprising: a first tubular component having a first sealing surface;a second tubular component having a second sealing surface, said first and second sealing surfaces being in facing relationship with one another when said first and second components are coupled together;one of said first and second sealing surfaces having a metallic film layer having a thickness that transforms from a first, solid state when a pressurized, heated fluid is not flowing through the tubular components, into a second, liquefied metal layer only after said metallic film layer is heated by the pressurized, heated fluid flowing through said apparatus to a temperature that exceeds a melting temperature of a metal from which said metallic film layer is formed, said thickness of said metallic film layer, once having turned into the liquefied metal layer, being sufficient to form a seal between said sealing surfaces, while said metallic film layer is maintained in a liquefied state by heat from said pressurized, heated fluid, as said pressurized, heated fluid flows through said coupling apparatus, and to remain disposed between said sealing surfaces when said pressurized, heated fluid is flowing under a pressure of at least approximately 500 pounds per square inch; andwherein said metallic film layer is applied by at least one of electroplating, physical vapor deposition and sputtering, onto its respective sealing surface. 2. The apparatus of claim 1, wherein said coupling apparatus forms a dynamic beam seal fitting. 3. The apparatus of claim 1, wherein said one of said sealing surfaces comprises a surface of a V-ring seal component. 4. The apparatus of claim 3, wherein a plurality of surfaces of said V-ring component are covered with said metallic film layer. 5. The apparatus of claim 1, wherein said metal of said metallic film layer comprises silver. 6. The apparatus of claim 1, wherein said metal of said metallic film layer comprises gold. 7. The apparatus of claim 1, wherein said metal of said metallic film layer comprises copper. 8. The apparatus of claim 1, wherein said metal of said metallic film layer comprises a brazeable alloy. 9. The apparatus of claim 1, wherein said first and second tubular components comprise tubular components adapted for use with a fluid having a pressure of at least about 500 pounds per square inch. 10. The apparatus of claim 1, further comprising a third component having a third sealing surface, and wherein said one of said first and second sealing surfaces having said liquefied metal film layer comprises a V-ring seal component, said V-ring seal component being disposed between said third component and the other one of said first and second tubular components. 11. A dynamic beam seal coupling apparatus comprising: a first tubular component having a first, generally planar sealing surface;a second tubular component having a second, generally planar sealing surface, said first and second sealing surfaces being arranged in facing relationship with one another when said first and second tubular components are coupled together;one of said first and second sealing surfaces having a metallic film layer deposited thereon that assumes a solid state prior to a pressurized, heated fluid of at least about 500 psi being flowed through the first and second tubular components, and only then transforms into a liquefied metal layer when said metallic film layer is exposed to said pressurized, heated fluid, and wherein said pressurized, heated fluid has a temperature that exceeds a melting temperature of a metal from which said metallic film layer is formed, said liquefied metal layer being sufficient to form a liquid seal between said sealing surfaces while said metallic film layer is maintained in a liquefied state by heat from said pressurized, heated fluid;wherein said metallic film layer has a thickness between greater than about 0.001 inch and up to about 0.002 inch, prior to transforming into said liquefied metal layer; andwherein said metallic film layer is electroplated onto said one of said first and second surfaces. 12. The apparatus of claim 11, wherein said metal of said metallic film layer comprises gold. 13. The apparatus of claim 11, wherein said metal of said metallic film layer comprises silver. 14. The apparatus of claim 11, wherein said metal of said metallic film layer comprises copper. 15. The apparatus of claim 11, wherein said metal of said metallic film layer comprises a brazeable alloy.
