Marieco, LLC

Marieco, LLC, a for-profit small business based in Leeds, Alabama, supplies high-pressure industrial water valve parts and hydraulic fluid control components to federal agencies as a prime contractor operating under small-business set-asides and full-and-open competition. The vendor competes exclusively on purchase orders, with all twenty-nine awards in its federal footprint classified as prime contracts (100% prime, 0% sub), totaling $719 thousand in combined potential value across nearly two decades of federal work.

Marieco's capability portfolio centers on pressure relief valves, air relief valves, flow-safe relief valves, pilot valves, FLEXFLO low-pressure tubes, and Baker Hughes Mooney flex-flow tubes — industrial valve and hydraulic component supply routed through both direct procurement and merchant-wholesaler intermediaries. Recent awards include a $27,806.82 total-small-business purchase order from NASA's Shared Services Center on August 3, 2026, for Baker Hughes Mooney flex-flow tubes (4-inch and 6-inch 150 lb units with nitrile seals) for the A1 Test Stand at John C. Stennis Space Center, Mississippi, with completion by December 14, 2026; a $13,204.72 full-and-open purchase order from NASA Shared Services Center on August 8, 2025, for a FLEXFLO 6-inch low-pressure tube, completing December 10, 2025; and a $21,634.77 purchase order from NASA Shared Services Center on May 16, 2022, for spare pressure relief valves for the NTREES Facility.

Customer concentration is heavily skewed toward NASA. The top two customer components account for 72% of awards by count and 80% of combined potential value: NASA Marshall Space Flight Center placed twelve awards ($408 thousand) and NASA Shared Services Center placed seven awards ($131 thousand), with the Department of the Navy accounting for two additional awards totaling $37 thousand. Award frequency is sparse — one award annually or fewer across the last five years — with only one award ($28 thousand) reaching ultimate completion inside the next twenty-four months. Top NAICS categories are industrial valve manufacturing (nine awards) and industrial machinery and equipment merchant wholesaling (five awards).
