SEANAIR, LLC

SEANAIR, LLC specializes in the precision manufacturing of mission-critical aerospace and defense components, with deep expertise in bearing systems, hydraulic fittings, and high-integrity fasteners. The company produces sleeve bearings, centering plugs, and fabricated pipe assemblies used in aircraft propulsion, flight control, and mechanical transmission systems. Their technical capabilities span tight-tolerance machining of metallic components, including ball and roller bearings, threaded fasteners, and custom fittings designed for extreme environmental and operational demands. SEANAIR’s differentiation lies in its ability to deliver small-batch, high-reliability parts for complex military platforms, consistently meeting stringent military specifications for material integrity, dimensional accuracy, and traceability. The contractor maintains a consistent and exclusive relationship with the Department of Defense, supplying components for aircraft, armored vehicles, and guided missile systems. Their work supports maintenance, repair, and overhaul (MRO) operations across naval, air, and ground platforms, with a focus on legacy and next-generation defense systems requiring certified replacement parts. SEANAIR’s contract history reflects a pattern of repeat engagement for critical subsystems where interchangeability, durability, and rapid turnaround are essential. Industry focus centers on NAICS 336413 for aircraft auxiliary equipment and 332991 for bearing manufacturing, with complementary work in fabricated pipe systems (332996) and fastener production (332722). This positions SEANAIR as a niche supplier to defense OEMs and tier-one integrators requiring qualified, non-commercial off-the-shelf (COTS) components for high-stress environments. SEANAIR, LLC is a small, privately held business based in Farmingdale, New York, with no federal certifications on record. The company operates as a specialized manufacturing entity serving the U.S. defense industrial base, leveraging localized engineering and production capabilities to support mission-essential supply chains.
