COASTAL WATERS SALES AND SERVICE, LLC

Coastal Waters Sales and Service, LLC specializes in the precision manufacturing of metal and plastic piping components, flanges, unions, and blind fittings for defense applications. Their core capabilities center on the fabrication of high-integrity valve and pipe fittings using carbon and other engineered metals, with demonstrated expertise in ANSI/ASME-compliant components for mission-critical naval, land, and aerospace systems. The contractor delivers custom-engineered solutions including threaded and weld-neck flanges, pipe unions, and specialized blind flanges, ensuring dimensional accuracy, material traceability, and compliance with military specifications. Their technical proficiency spans metal stamping, CNC machining, and surface finishing processes, with a focus on reliability under extreme pressure and environmental conditions. A key differentiator is their ability to rapidly produce low-volume, high-precision parts with tight tolerances, often for urgent operational needs. The company maintains a consistent and exclusive relationship with the Department of Defense, supplying mission-critical fluid system components across multiple naval and ground force platforms. Their work supports sustainment, modernization, and repair programs requiring certified, defense-grade hardware that meets MIL-SPEC and ASTM standards. Primarily operating under NAICS 332919, the contractor focuses on the manufacturing of metal valve and pipe fittings—specifically flanges and unions critical to hydraulic, fuel, and seawater systems. They also produce plastic pipe fittings under NAICS 326122 and signage under 339950, indicating a flexible, multi-material approach to supporting diverse military infrastructure needs. As a Women-Owned Small Business headquartered in Chesapeake, VA, Coastal Waters leverages its small business status to provide agile, responsive manufacturing services to federal procurement channels. The firm’s certifications enhance its eligibility for set-aside contracts, and its strategic East Coast location supports efficient logistics to major defense hubs and naval shipyards.
