About the company

South-Tek Systems, LLC manufactures nitrogen generation equipment, gas handling systems, and components for Department of Defense and federal civilian agencies as a prime contractor, competing predominantly in full-and-open procurements without set-aside designations. The company is a for-profit limited liability company and manufacturer of goods headquartered in Wilmington, North Carolina, with a small-business designation and a twenty-one-year SAM.gov registration history dating to 2005.

South-Tek's capability portfolio centers on fixed and mobile nitrogen generation systems (PSA and membrane technologies), pressure vessels, hoses, fittings, and replacement components for industrial gas and fluid handling applications across military installations and federal laboratories. Representative prime work includes a $138,000 delivery of an N2GEN 260S-T1 PSA nitrogen generator to Naval Air Warfare Center (award date June 25, 2026); an $8,500 total-small-business purchase order from ACC Redstone for nitrogen generator operator training, system calibration, and commissioning at Letterkenny Army Depot (award date May 6, 2026); a $9,978 urgent repair contract from Air Education and Training Command for nitrogen generator maintenance at Joint Base San Antonio-Lackland (award date June 23, 2025); and a $10,589 nitrogen machine repair task for the Marine Corps at Camp Pendleton (award date September 15, 2022).

Customer concentration reflects deep Defense Logistics Agency penetration. The top five funding entities account for 76% of recent awards by count: Defense Logistics Agency Land and Maritime leads with 64 awards ($50 thousand combined potential value), followed by DLA Troop Support Construction and Equipment (20 awards, $140 thousand), DLA Aviation (14 awards, $6 thousand), United States Marine Corps (10 awards, $1.5 million), and Department of Agriculture Agricultural Research Service (8 awards, $62 thousand). By dollar value, however, the Marine Corps anchors the portfolio with $1.5 million across ten awards, while GSA Federal Acquisition Service places two awards worth $1.3 million. The divergence reflects South-Tek's role as a high-volume parts and component supplier through DLA (small unit values) and a system integrator and equipment prime for operational customer agencies.

South-Tek holds a seat on the GSA Multiple Award Schedule with 26 task orders ($1.7 million combined potential value) and maintains positions on two indefinite delivery contracts (SPE4A724D0194 and FA865120D0003). The vendor's NAICS and PSC footprint spans Analytical Laboratory Instrument Manufacturing (30 awards), All Other Miscellaneous General Purpose Machinery Manufacturing (23 awards), Rubber and Plastics Hoses and Belting Manufacturing (18 awards), and Industrial Gas Manufacturing (12 awards), with PSC concentration in Gas Generating and Dispensing Systems (28 awards) and Hose and Flexible Tubing (25 awards).

Award activity has declined sharply. South-Tek recorded fourteen prime awards in 2022 but only one in 2024, two in 2025, and two in 2026 year-to-date. Combined potential value across all awards totals $4.1 million, with $3.8 million obligated. Recent subcontract work includes oxygen-nitrogen generator supply to Atlantic Diving Supply, Inc. on three awards (most recent January 13, 2025) and research and development for emerging fuze technologies and energetic materials under University of Dayton. The vendor serves twenty-eight distinct federal customer agencies but faces a contracting environment heavily weighted toward low-dollar DLA transactional parts orders rather than higher-value system integration or development work.
