NAICS 332912

Overview

The North American Industry Classification System is the framework federal statistical agencies use to categorize business establishments for economic data collection and reporting. Developed under the Office of Management and Budget and implemented in 1997, NAICS was created jointly by the United States, Canada, and Mexico to improve comparability of business statistics across North America. It is reviewed every five years to reflect structural changes in the economy. ¹

In NAICS 2022, 332912 covers establishments primarily engaged in manufacturing fluid power valves and hose fittings, with illustrative examples that include hydraulic and pneumatic valves, hose and tube fittings, hose assemblies for fluid power systems, and fluid power aircraft subassemblies. The Census Bureau uses this classification across surveys and the Economic Census to tabulate industry data and distinguish it from adjacent industries such as industrial valves and other metal valve manufacturing. ²

What this NAICS covers

• Manufacturing hydraulic and pneumatic valves for fluid power applications. ²
• Producing hydraulic and pneumatic hose and tube fittings for fluid power systems. ²
• Assembling hose assemblies specifically for fluid power systems. ²
• Manufacturing fluid power aircraft subassemblies. ²
• Supplying components integral to hydraulic and pneumatic fluid conveyance and control (e.g., couplings, connectors) within fluid power systems. ²
• Establishments whose primary output is fluid power valves and hose fittings, distinguished from industrial or plumbing valves. ²
