Stainless Steel Pipe Coupling is a short length of threaded pipe commonly used to connect valves, fittings, and piping components in industrial systems. It is typically specified by its total length, including the threaded ends, ensuring accurate installation and compatibility. Depending on the application, pipe nipples are available in various configurations, including plain barrel types and designs with a center hex section for easier tightening with standard tools. These fittings provide secure connections, reliable performance, and are widely used across oil & gas, chemical, water treatment, and general industrial piping applications.
