COLD LLC

COLD LLC specializes in the precision manufacturing and engineering support of mission-critical components for defense and industrial systems. The company delivers high-integrity gaskets, seals, valves, fluid control devices, and environmental control systems, often under sole-source arrangements for complex military applications. Their technical expertise spans metal fabrication, rubber and polymer sealing technologies, automated instrumentation, and mechanical subsystem integration, with demonstrated proficiency in producing components for aircraft, compressed air systems, and fluid handling infrastructure. COLD LLC’s ability to deliver custom-engineered parts—such as blade guides, liquid indicators, and totalizing meters—under tight tolerances underscores a deep understanding of aerospace and defense performance requirements. The contractor maintains a consistent and primary relationship with the Department of Defense, supplying components across land, air, and maritime platforms. Work includes direct manufacturing of metallic tubing, industrial valves, and environmental control units critical to vehicle, vessel, and equipment sustainment. Their contract history reflects a pattern of repeat engagements for repair parts and refurbishment services, indicating trusted status as a reliable supplier for lifecycle support and maintenance operations. Industry focus centers on manufacturing under NAICS 339991 (gaskets and seals), 332911 (industrial valves), and 541330 (engineering services), positioning COLD LLC as a niche provider of sealed systems and mechanical subsystems for high-reliability environments. Their vertical specialization lies in precision fluid control, environmental monitoring, and mechanical component fabrication for defense-grade applications. COLD LLC is a small business entity headquartered in Milford, Connecticut, with no federal certifications on record. Despite this, their sustained DoD contract activity and technical specificity in manufacturing and engineering services establish them as a capable, focused supplier within the defense industrial base, serving specialized needs in mechanical and environmental subsystems without reliance on formal small business designations.
