FLUID COMPONENTS INTERNATIONAL LLC

Fluid Components International LLC specializes in the design and manufacture of precision fluid and thermal control systems for defense and aerospace applications. Their core capabilities center on thermostatic switches, flow transducers, and motion-sensing transducers—critical components used in aircraft fuel systems, switchgear, and environmental control units. The company demonstrates deep expertise in high-reliability sensing and control devices, with a focus on thermal regulation, fluid flow monitoring, and electrical switching mechanisms that operate under extreme environmental conditions. Their products are engineered for mission-critical environments where precision, durability, and repeatable performance are non-negotiable, positioning them as a trusted supplier of embedded instrumentation for harsh operational settings. The contractor maintains a strong and consistent relationship with the Department of Defense, supplying specialized components for aviation and military systems. Their work supports aircraft fuel-air flow management, thermal protection systems, and switchgear applications critical to platform safety and operational readiness. While DLA Aviation is also represented in their award history, the overwhelming majority of engagements are directly with DoD entities, indicating a focused alignment with defense procurement cycles and technical specifications for military-grade hardware. Industry focus is firmly rooted in NAICS 335313 (switchgear and switchboard apparatus manufacturing) and 334519 (other measuring and controlling device manufacturing), where they deliver custom-engineered sensors and control devices that interface with electrical, hydraulic, and pneumatic systems. Their market positioning is that of a niche manufacturer serving defense aerospace systems integrators requiring certified, low-volume, high-integrity components. Fluid Components International LLC is a small business structured as a 2L entity, headquartered in San Marcos, California. While no formal government certifications are listed, their consistent delivery of mission-critical components to the DoD reflects a proven track record in meeting stringent military quality and traceability standards. Their geographic proximity to defense aerospace hubs enhances responsiveness and collaboration with defense contractors and military engineering teams.
