Oxygen Liquefaction Cryocooler Fluid Transfer Line

NASA Shared Services Center is seeking fluid transfer line components for an oxygen liquefaction cryocooler system at NASA Glenn Research Center in Cleveland, Ohio. The procurement involves two flex hose assemblies and four female bayonet fittings made of 304/316 stainless steel, specifically designed to transfer gaseous neon between a test tank and an integrated refrigeration unit. The solicitation uses a Lowest Price Technically Acceptable (LPTA) evaluation method, which means the contract will be awarded to the responsible offeror with the lowest price that meets all technical requirements. Potential bidders must be registered in SAM.gov and include their CAGE/UEI code, FOB destination details, lead time for delivery, and point of contact information. Quotes are due by May 6, 2025, at 9:00 a.m. CT, with a 30-day quote validity period.

The solicitation is not set aside for any specific business category, using an open market approach under NAICS category 335999 for miscellaneous electrical equipment manufacturing. The technical specifications require a 1" x 3" vacuum-jacketed flex hose that is 25' long, capable of operating at pressures up to 150 psig and temperatures between 90K to 300K. Vendors must provide three copies of documentation at delivery, including a Certificate of Conformance, material certifications, and comprehensive piping system design documentation per ASME B31.3 standards. The proposal must include a fabrication and delivery schedule, with optional pricing for an accelerated 12-16 week delivery timeline. While specific award value is not disclosed, the procurement is focused on precise, high-performance cryogenic fluid transfer line components for NASA's research and testing requirements.
