This is a Recommendation and Determination to Solicit from One Source or Brand Name document issued by NASA's Shared Services Center.

The document recommends a sole source procurement for the inspection and rebuild of 15 LOx Clean valves from Eastern Controls, Inc., with an estimated cost and 8-month performance period. The justification cites that Eastern Controls is the Masonneilan Authorized Repair Center for this specific brand of valves and the only company officially authorized to work on them. The valves require LOx cleaning with highly specialized handling and cleaning procedures. Eastern Controls is identified as the approved vendor with significant demonstrated experience and backing from the manufacturer. The document addresses the impact of using an alternative vendor, noting that improper handling of pressurized liquid oxygen valves could result in system contamination, catastrophic failures, and potential safety risks to personnel and facility damage. The document includes fields for technical user name, date, title, and office information, with space for additional comments. The form version is V3.0 from January 2026.
