AIR-LOCK, INCORPORATED

AIR-LOCK, INCORPORATED specializes in the precision manufacturing of mission-critical hardware components and fluid system interfaces for defense and aerospace applications. The company’s core capabilities center on the fabrication of quick-disconnect couplings, bayonet connectors, valve parts, and specialized hardware assemblies, primarily using high-integrity metalworking and precision machining techniques. Their technical expertise includes the design and production of threaded and sealed fluid system components compliant with military and aerospace specifications, with demonstrated proficiency in producing parts for pneumatic, hydraulic, and environmental control systems. Key differentiators include consistent on-time delivery of low-volume, high-reliability components and deep familiarity with defense-grade material standards and dimensional tolerances. The contractor maintains a strong and sustained relationship with the Department of Defense, supplying essential fluid system fittings and mechanical assemblies for ground, airborne, and naval platforms. They also deliver specialized training hardware and support components to the National Aeronautics and Space Administration, indicating experience in both operational and educational aerospace systems. Their work for these agencies reflects a pattern of repeat engagement on critical, non-commercial parts requiring strict traceability and quality control. Industry focus is anchored in hardware manufacturing (NAICS 332510) and fabricated pipe and fitting production (NAICS 332996), with supplementary work in commercial machinery and aircraft systems. This positions AIR-LOCK, INCORPORATED as a niche supplier for defense and space programs requiring ruggedized, small-batch components that bridge standard industrial practices with military specifications. As a small business structured as a 2L entity based in Milford, Connecticut, AIR-LOCK, INCORPORATED operates with agility and precision, serving government markets through direct manufacturing without third-party intermediaries. While no formal government certifications are listed, their consistent delivery of mission-essential hardware suggests adherence to AS9100, ISO 9001, or similar quality management frameworks common in their sector.
