DN15-DN150, SCH40-SCH160 High Corrosion Resistance Stainless Steel Pipe Union
DN15-DN150, SCH40-SCH160 High Corrosion Resistance Stainless Steel Pipe Union
►Products Description
A pipe union fitting is a practical connector used in plumbing, fluid handling, and industrial systems to join two pipes or male-threaded components. It comprises three parts: two female-threaded ends and a central tightening nut that securely connects them. This design enables easy assembly and disassembly without rotating the pipes, making it suitable for systems needing frequent maintenance or expansion. Stainless steel unions, available in 304 and 316 grades, feature tapered NPT threads for leak-proof, durable, and corrosion-resistant connections. They are widely used in HVAC, plumbing, and industrial applications for extending or modifying pipe runs without disrupting the system.
