Cold zone seal comparison fixture

Separately made opposing cold ferrous witness faces, retention and gas-stimulus interface for trial copper sealing without requiring the final shell as its own verification tool. Geometry, stiffness, preload, cooling and leakage discrimination unqualified.

Known Parts and Tools

The selected route supplies this page's inventory and the map's dependency links from one record. Further requirements may be missing; review flags do not prove physical suitability.

Making outline

1. Assemble paired independently made cooled witness faces in rigid reaction yoke with gravity lever compression, isolated gas/water interfaces, and separate background and leakage comparison hardware
2. Detailed procedure and acceptance remain unresearched.

What remains unresolved

• Manufacture, quantities, suitability and complete inventory remain unreviewed.
• Current memory-first method needs source and compatibility review.
