STS Distribution Solutions, LLC

STS Distribution Solutions, LLC, doing business as Air-Pro, supplies nonmetallic and metal hose assemblies, tubing assemblies, loop clamps, and related fluid transfer components to the Defense Logistics Agency as a prime contractor, with 3,255 prime federal contract awards (100% of recent activity) spanning purchase orders and indefinite delivery contracts under no set-aside designation and total small business set-asides.

Air-Pro is a for-profit limited liability company headquartered in Palm City, Florida, and registered in the System for Award Management since 2012. The vendor operates as a child entity under parent company Aviation Solutions Holdings LP, also Florida-based. The company competes predominantly in full-and-open procurement, though it holds active set-aside positions; across the recent award footprint, roughly 97% of dollars flow through non-set-aside purchase orders and IDCs, while set-aside contracts (Total Small Business designation) account for a smaller share of overall volume and value. Primary NAICS categories are All Other Miscellaneous Fabricated Metal Product Manufacturing (2,263 awards) and Rubber and Plastics Hoses and Belting Manufacturing (360 awards); primary PSC is Hose and Flexible Tubing (3,188 awards).

Customer concentration is extreme and single-agency dependent. The Defense Logistics Agency Land and Maritime funds 3,169 of 3,256 awards (97% by count), representing $29.8 million of $30.6 million combined potential value (97% by dollars). Secondary DLA customer divisions—Aviation, Troop Support Hardware, and Troop Support Construction and Equipment—together account for fewer than 100 awards and under $800 thousand in value. A single sub-award appears in the source: aircraft maintenance parts procurement under prime contractor AAR Government Services, Inc. for the U.S. Navy, valued at undisclosed amount, awarded January 23, 2024.

Air-Pro holds multiple indefinite delivery contracts with DLA Land and Maritime. The source identifies five active or recently completed IDC vehicles: a non-set-aside $250 thousand single-award IDC for nonmetallic hose assemblies (NSN 4720009293977) running through December 30, 2025; a Total Small Business single-award $250 thousand IDC for nonmetallic hose assemblies (NSN 4720006843568) also through December 30, 2025; a Total Small Business single-award $250 thousand IDC for nonmetallic hose assemblies (NSN 4720006182847) running through July 31, 2025; a non-set-aside $250 thousand IDC for nonmetallic hose assemblies (NSN 4720016062775) that completed April 29, 2025; and a newly awarded non-set-aside $250 thousand single-award IDC for clamp and loop hardware (NSN 5340006643774) running through August 26, 2026. Each IDC is structured as an automated indefinite delivery vehicle with guaranteed minimum quantities and estimated annual delivery order frequencies (ranging from 4 to 10 orders per year) and 65- to 79-day delivery timelines to DLA distribution centers in CONUS and OCONUS locations.

Activity trajectory shows significant decline. Awards per year fell from 293 in 2022 to 47 in 2026 year-to-date (through April 9, 2026)—a drop of 84% from peak. This pattern is consistent with a vendor whose business model centers on high-volume, low-dollar-value purchase orders issued under standing IDCs; the 2026 slowdown likely reflects normal quarterly variability in DLA requisition cycles rather than structural loss of business. Combined obligated dollars across all awards total $15.9 million (52% of $30.6 million potential value), indicating partial execution of awarded ceilings. Within the next twenty-four months, 17 awards with combined potential value of $510 thousand reach ultimate completion, representing recompete exposure primarily tied to IDC renewals and small-value purchase orders.

Award scope spans nonmetallic hose assemblies (dominant product), metal hose assemblies, loop clamps, tubing assemblies (nonmetallic and metal), turbine oil tubes, and plastic spiral tubing. Representative recent prime awards include a $65.2 million nonmetallic hose assembly purchase order (August 24, 2025, 6 units, 88-day delivery); a $185.2 thousand metallic hose purchase order set aside for total small business (May 2, 2025, 48 units, February 23, 2026 completion); a $155.2 thousand nonmetallic hose assembly purchase order set aside for total small business (February 25, 2026, 46 units, delivery to DLA Distribution Jacksonville); and a $134.1 thousand nonmetallic hose assembly purchase order set aside for total small business (March 24, 2026, 145 units, delivery to DLA Distribution Depot Hill). Work is performed at the contractor's Palm City, Florida facility; deliveries are made to DLA distribution depots and consolidation points across military logistics infrastructure.

The company's federal portfolio is characterized by narrow product specialization, intense customer concentration on a single DLA customer division, and reliance on indefinite delivery contract vehicles that enable rapid issuance of firm fixed-price purchase orders for standardized National Stock Number items. Subcontract presence is negligible. Set-aside participation occurs through Total Small Business designations on a subset of IDCs and larger purchase orders, but the majority of dollars flow through unrestricted full-and-open competition. The steep decline in award frequency since 2022, combined with modest recompete exposure in the next twenty-four months, signals a vendor whose growth trajectory has flattened and whose continued federal market presence depends on ongoing DLA Land and Maritime demand for commodity fluid transfer components and routine IDC renewal cycles.
