About Fluid Components International LLC
Fluid Components International LLC, a San Marcos, California-based aerospace-focused manufacturer and child company of Process Sensing Technologies Corp., supplies motional transducers, flow switches, thermal sensors, and related flow and level measurement instrumentation to the Department of Defense as a prime contractor on full-and-open purchase orders and delivery orders, with a secondary presence as a subcontractor to Boeing, Northrop Grumman, and Lockheed Martin on helicopter and fixed-wing aircraft programs. The company operates its Aerospace Division without SBA set-aside designation on the vast majority of federal work, though it qualifies as a small business and has received total small business set-aside awards; recent prime activity totals $5.1 million in combined potential value across 47 awards, with an additional 21 subcontract engagements.
FCI's federal customer base concentrates sharply on Defense Logistics Agency Aviation, which accounts for 18 awards and $4.1 million in combined potential value (80% of the disclosed prime portfolio). The Department of the Navy Naval Supply Systems Command (8 awards, $388 thousand), NASA Johnson Space Center and NASA Shared Services Center (combined 6 awards, $316 thousand), and the Army Materiel Command Aviation and Missile Life Cycle Management Command (5 awards) round out FCI's top five customers; these five entities cover 66% of the award count but DLA Aviation dominates the dollar concentration. FCI's capability footprint centers on motional transducers and thermal dispersion flow switches for military helicopter platforms, particularly the AH-64E Apache and H-60 systems. Recent representative prime awards include a $405,384 DLA Aviation delivery order for motional transducers (NSN 6695-01-665-9760) issued January 27, 2026, a $136,640 delivery order for the same transducers issued February 15, 2024, and a $109,340 Naval Supply Systems Command purchase order for fuel-air flow sensors issued March 24, 2025. FCI operates under a single-award Indefinite Delivery Contract with DLA Aviation (SPE4A621D0151, $1.2 million ceiling), which generated 9 task orders, and holds IDCs with the Air Force (FA862819D1000, 3 task orders) and Navy (N0001920G0005, 2 task orders) under which it delivers specialized sensing components.
Activity has accelerated year over year, rising from 3 awards in 2022 to 15 in 2025, with 5 awards already recorded in 2026. Three awards (combined potential value $510 thousand) reach ultimate completion in the next twenty-four months, creating modest recompete exposure. FCI's subcontract footprint is material — 31% of all awards fall into the sub category — and is anchored by Boeing, where FCI supplies flow sensors and transducers to the AH-64 Apache Performance-Based Logistics program, Apache advanced procurement and full-rate production efforts, B-52 Radar Modernization, and CH-47F helicopter long-lead items. Northrop Grumman engages FCI for flow instrumentation on the E-2D Advanced Hawkeye aircraft and aerial refueling retrofit kits, and Lockheed Martin pulls sensor flow components for F-35 long-lead items. FCI's award portfolio spans Aircraft Manufacturing (17 awards), Other Measuring and Controlling Device Manufacturing (13 awards), and Instruments and Related Products Manufacturing for Measuring, Displaying, and Controlling Industrial Process Variables (12 awards), with dominant PSC categories of Combination and Miscellaneous Instruments (15 awards) and Switches (12 awards), reflecting a pure-play specialization in aerospace flow and level sensing components for military rotary-wing and fixed-wing platforms.
