NOR-CAL PRODUCTS, INC.

NOR-CAL PRODUCTS, INC. specializes in the precision manufacturing of high-performance vacuum system components, including fabricated pipe fittings and extreme high vacuum (XHV) gate valves engineered for mission-critical applications. Their technical expertise lies in metallurgical fabrication, vacuum-compatible material selection, and ultra-high vacuum sealing technologies, with a focus on components that maintain integrity under extreme thermal and pressure differentials. The company’s capability centers on custom-engineered solutions for environments requiring stringent leak-tightness, outgassing control, and mechanical stability—critical for space and defense systems operating in hard vacuum conditions. Their specialization in rough pump vacuum fittings and XHV gate valves demonstrates deep competency in vacuum engineering standards, including ISO 1607 and ASTM E595, and an ability to meet tight tolerances for aerospace and defense instrumentation. NOR-CAL PRODUCTS, INC. has delivered specialized vacuum hardware to both NASA and the Department of Defense, supporting spacecraft thermal control systems and laboratory-grade analytical instrumentation. Their work for NASA involves vacuum-compatible fluid and gas handling components, while their DoD contracts focus on high-reliability valves used in sensor systems and test chambers requiring extreme environmental simulation. These engagements reflect a pattern of trusted supplier relationships in niche, high-stakes technical domains. The company’s primary industry focus is on fabricated pipe and pipe fitting manufacturing (NAICS 332996) and analytical laboratory instrument manufacturing (NAICS 334516), positioning them as a specialized supplier to advanced scientific and defense sectors requiring vacuum-tight, non-contaminating components. Their market niche is defined by precision fabrication for ultra-high vacuum systems used in space exploration and laboratory analytics. As a small, privately held business headquartered in Yreka, California, NOR-CAL PRODUCTS, INC. operates without federal certifications but maintains a focused, technical footprint in the government supply chain through direct, mission-critical manufacturing. Their geographic location supports regional defense and aerospace supply networks with agile, low-volume production capabilities.
