►Products Description
A pipe union fitting is a versatile connector used in plumbing, fluid handling, and industrial systems to join two pipes or male-threaded components. It consists of three parts: two female-threaded end pieces and a central tightening nut that securely joins them. This design allows for easy assembly and disassembly without rotating or moving the pipes, making it ideal for systems requiring frequent maintenance or expansion. Stainless steel union fittings, available in 304 and 316 grades, feature tapered NPT threads for leak-proof connections, ensuring durability and corrosion resistance. They are widely used in HVAC, plumbing, and industrial applications for extending or modifying threaded pipe runs without disrupting the entire system.
