What is claimed is: 1. A seal test device for testing the integrity of a metal seal ring of a metal seal between an upper flanged hub and a lower flanged hub with the metal seal ring in a seam between the upper and lower flanged hubs, the upper and lower flanged hubs held together with a plurality of studs and the hubs defining a channel for the flow of a channeled fluid therethrough, the test device comprising: an elastomeric seal in the lower flanged hub; a pressurization port through the lower flanged hub between the seam and the elastomeric seal; and a source of pressurized fluid for introducing pressurized fluid into the pressurization port. 2. The device of claim 1, further comprising: an upper recess in the upper flanged hub; a lower recess in the lower flanged hub; and a seal sleeve in the upper and lower recesses. 3. The device of claim 2, wherein the pressurization port opens into the lower recess. 4. The device of claim 2, wherein the metal seal spans the upper and lower recesses. 5. The device of claim 2, wherein the metal seal is positioned at a spaced apart position from the sleeve.
