CLARK-RELIANCE LLC

Clark-Reliance LLC specializes in the precision manufacturing of mission-critical industrial components for defense systems, with deep expertise in glass tubing, sight indicators, gaskets, and custom metal fabrications. The company produces high-integrity liquid sight indicators, nonmetallic tubing, and sealing devices engineered for harsh operational environments, often used in fluid systems, instrumentation panels, and pressure monitoring applications. Their technical capabilities span precision glass forming, metallurgical fabrication, and sealing system assembly—ensuring dimensional accuracy, leak-tight performance, and compliance with military specification requirements. A key differentiator is their ability to rapidly prototype and produce small-batch, high-reliability components for specialized defense equipment, particularly where standard commercial parts are unsuitable. The contractor maintains a consistent and focused relationship with the Department of Defense, supplying components critical to naval, aerospace, and ground vehicle systems. Their work supports maintenance, repair, and overhaul programs across multiple military branches, delivering parts that ensure the functionality of instrumentation, fluid control, and containment systems in field-deployed assets. Industry focus centers on manufacturing under NAICS codes 327215 (glass tubing), 334519 (sight indicators and measuring devices), and 339991 (gaskets and seals)—all essential to industrial process control and fluid system integrity. The company positions itself as a niche supplier of mission-essential hardware, serving defense contractors and government depots requiring certified, low-volume, high-precision components. Clark-Reliance LLC is a small business based in Strongsville, Ohio, with no federal certifications on record. Their geographic presence is localized but strategically aligned with defense supply chains in the Midwest, supporting just-in-time delivery and rapid response to urgent military requirements. The company operates as a specialized fabricator, relying on technical agility and quality control rather than broad certification portfolios to compete in the defense industrial base.
