Fitzhugh Clifton

Fitzhugh Clifton, doing business as Hyperox Technologies, a San Diego-based sole proprietorship, manufactures and supplies precision sealing and packaging materials, industrial fasteners, and specialized mechanical components to the Department of Defense as a prime contractor on federal purchase orders and delivery orders. The company does not hold a government-wide contract vehicle or federal grant awards; it operates exclusively as a prime on individual task orders and purchase orders issued by defense agencies. Hyperox Technologies is a small business that competes predominantly in full-and-open procurements without reliance on set-aside categories, though a substantial minority of its awards carry total small business set-aside designations.

Hyperox Technologies' core capability footprint centers on the manufacture and supply of O-rings, preformed packing materials, gaskets, seals, retaining rings, and fastening components—National Stock Number (NSN) items critical to military equipment maintenance and naval logistics operations. The company holds two active indefinite delivery contracts with the Defense Logistics Agency: a $250,000 Land and Maritime IDC for preformed packing materials (awarded November 2021, designated as total small business set-aside) and a $250,000 Aviation IDC for retaining rings (awarded August 2021, no set-aside). Representative recent work includes a $29,370 delivery order from DLA Land and Maritime on March 18, 2026 for retaining rings, a $99,592.50 purchase order from DLA Aviation in January 2026 for screw assembly units, a $73,728 total small business set-aside purchase order from Naval Supply Systems Command in July 2024 for O-ring closure components, and a $43,125 non-set-aside purchase order from DLA Land and Maritime in January 2024 for non-metallic hose assemblies.

Customer concentration is heavily skewed to defense logistics and naval supply channels. The top five funding agencies account for 98 percent of recent awards: Defense Logistics Agency Troop Support Hardware dominates by potential value at $19.9 million across 699 awards, while Naval Supply Systems Command leads by award volume with 1,273 awards carrying $3.8 million in combined potential value. DLA Land and Maritime accounts for 571 awards worth $2.5 million, DLA Troop Support Construction and Equipment for 41 awards worth $145 thousand, and DLA Aviation for 23 awards worth $555 thousand. The vendor's award portfolio spans 2,647 prime contracts and delivery orders since 1992, with recent activity declining: 209 awards in 2022, declining to 90 in 2024, with 101 awards in 2025 and only 4 in 2026 year-to-date. One award worth $100 thousand reaches ultimate completion within the next twenty-four months, representing modest recompete exposure.

The vendor's award footprint is categorized almost entirely around NAICS 332722 (Gasket, Packing, and Sealing Device Manufacturing), which accounts for 763 of the company's recent awards, followed by NAICS 332722 (Bolt, Nut, Screw, Rivet, and Washer Manufacturing) with 384 awards. PSC-level concentration is similarly narrow: Packing and Gasket Materials (PSC 5330) dominate at 668 awards, O-Ring (PSC 5331) at 662 awards, with smaller volumes of guided missile maintenance equipment and fire control computing sights. Work is performed at the contractor's San Diego, California facility, with deliveries directed to military depots and supply locations worldwide. Hyperox Technologies operates solely as a prime contractor; the source carries no subcontractor relationships or sub-award activity, indicating the company manufactures components in-house rather than orchestrating supply chains.
