PATTERSON COONEY INC

Patterson Cooney Inc. specializes in the precision manufacturing of mission-critical metal and polymer components for defense and industrial applications. Their core capabilities include the production of valves, pipe fittings, gaskets, seals, springs, fuel separators, exhaust mufflers, and O-rings using advanced fabrication techniques. The company demonstrates deep technical expertise in metallurgy, rubber and plastic molding, and high-tolerance machining, delivering parts that meet stringent military and aerospace performance standards. Their ability to manufacture complex assemblies—from sensitive switches to helical springs and fabricated pipe systems—reflects a strong command of material science and assembly integration, with a focus on reliability under extreme environmental and mechanical stress. The contractor maintains a consistent and extensive relationship with the Department of Defense, supplying engineered components for ground vehicles, aircraft systems, and naval equipment. Their work supports logistics, propulsion, fluid control, and exhaust systems, indicating a trusted role in sustaining defense platform readiness. Contracts frequently involve parts requiring strict adherence to military specifications, suggesting established compliance with drawing controls, inspection protocols, and traceability requirements. Industry focus centers on manufacturing categories including metal valve and pipe fitting production, rubber and plastic hose manufacturing, and miscellaneous fabricated metal products. These NAICS codes reflect specialization in fluid handling, sealing systems, and mechanical power transmission components—key subsystems in military vehicles, aircraft, and heavy machinery. The firm positions itself as a niche supplier of mission-essential hardware, bridging the gap between high-volume production and low-quantity, high-reliability requirements. Patterson Cooney Inc. is a woman-owned small business based in New Lenox, Illinois, with a lean, agile structure optimized for responsive government contracting. The company’s certifications enhance its eligibility for set-aside programs, and its geographic presence supports timely delivery to defense supply chains across the Midwest and beyond.
