About the company
Simplex Americas LLC, a for-profit limited liability partnership based in Flemington, New Jersey, supplies original equipment manufacturer (OEM) stern tube seals, shaft couplings, propeller shaft seal kits, and marine engineering components to the U.S. Navy's Military Sealift Command as a prime contractor (69% of recent awards) and as a subcontractor to shipyard and maritime repair primes. The vendor operates without SBA set-aside designations on the majority of its prime footprint, competing on a full-and-open basis, though one award carries a Total Small Business set-aside designation and one prime award was 8(a) sole source.
Simplex's customer concentration is singular and high-stakes. The Department of the Navy's Military Sealift Command accounts for 12 awards and $2 million in combined potential value — 97% of all active awards by count and 91% of all dollar value. The vendor's secondary customer base consists of the Department of the Army Corps of Engineers Engineering District Memphis (5 awards, $56 thousand), the Department of Homeland Security Coast Guard (4 awards, $22 thousand), and Naval Sea Systems Command (9 awards, $14 thousand). Recent named prime work includes a $308,750 firm fixed-price purchase order awarded May 29, 2026, for USNS Lucy Stone stern tube system parts (AFT and FWD chrome split seals and liner/cast iron split seals) with delivery mandated to Naval Base Norfolk by January 1, 2027; a $303,236 purchase order from June 2025 for USNS Robert F. Kennedy stern tube system overhaul material; and a $286,045 sole-source purchase order from July 2024 for USNS Earl Warren stern tube seal system components. A $24,640 Total Small Business purchase order from January 2022 with the Army Corps of Engineers for machinist materials diversifies the customer mix marginally.
Activity has accelerated sharply — two awards in 2019, five in 2022, eleven in 2025, and one in 2026 — with only one award ($309 thousand) reaching ultimate completion within the next twenty-four months. In the subcontractor role, Simplex supplies stern tube seals and seal overhaul labor to BAE Systems Maritime Solutions San Diego Inc. on multiple USS Green Bay and USS Somerset fiscal year 2025 docking selected restricted availability work (most recent awards December 2025); provides simplex seal kits (AFT and FWD 750 mm) to Crowley Government Services for maritime prepositioning force vessel operation and maintenance (November 2025); and furnishes stern tube seal overhaul labor and material to Vigor Marine LLC for USNS Earl Warren post-shakedown availability work (October 2025). Simplex's capability portfolio centers on OEM stern tube seal systems, propeller shaft seals, shaft couplings, and on-site technical representation for naval replenishment oilers and auxiliary vessels. The vendor's top NAICS concentration is Ship Building and Repairing (16 awards), followed by Gasket, Packing, and Sealing Device Manufacturing (7 awards).
