Flexible Tubing and Microfluidic Network Fabrication

NASA is soliciting proposals for the manufacture of flexible, leak-proof microfluidic tubing networks designed to be integrated into the Liquid Cooling and Ventilation Garment to ensure reliable coolant circulation under the extreme conditions of vacuum and thermal variation. The tubing must maintain structural integrity and fluid-tight performance during dynamic operational environments, requiring advanced materials and precision fabrication techniques to meet stringent aerospace standards. This subcontract targets the development of a custom microfluidic system that enables efficient thermal regulation for astronaut mobility and safety during spaceflight missions. The opportunity is open for submission until May 5, 2026, with the North American Industry Classification System code 326299 indicating it falls under other plastic product manufacturing. The place of performance is designated as Houston, Texas, 77058, and the contract is being managed by the NASA Shared Services Center under the National Aeronautics and Space Administration. Proposals must demonstrate technical feasibility, scalability, and proven experience in producing high-reliability fluidic systems for space applications, with an emphasis on durability, compatibility with existing LCVG hardware, and performance validation under simulated space conditions.
