Ultra-High Vacuum (UHV) Sealing & Materials Supply

The contract calls for the supply of vacuum-compatible metal seals, gaskets, and non-outgassing materials specifically engineered for operation in ultra-high vacuum environments at or below 10⁻⁷ Torr. These components must meet stringent performance criteria to ensure structural integrity, thermal stability, and minimal contamination under extreme vacuum conditions, making them essential for critical aerospace and scientific instrumentation systems. The materials must be free of volatile compounds that could compromise vacuum integrity or interfere with sensitive experiments, and all items are subject to rigorous quality assurance standards consistent with NASA's mission-critical requirements. The solicitation is issued as a subcontract under the NAICS code 332996 for Other Fabricated Metal Product Manufacturing by the NASA Shared Services Center on behalf of the National Aeronautics and Space Administration. Responses are due by August 3, 2026, and the opportunity was posted on July 29, 2026. The place of performance and point of contact details are not specified, but the delivery and compliance must align with NASA’s operational needs across its mission facilities. All vendors are expected to demonstrate proven experience in supplying UHV-grade components and adherence to cleanroom and contamination control protocols.
