Three Piece Female NPT Union
Three Piece Female NPT Union
The stainless steel Three Piece Female NPT Union is designed to provide a secure, removable connection between two male-threaded NPT components in industrial piping systems. Its three-piece design allows for easy disassembly without rotating the connected pipesโideal for maintenance, system upgrades, or tight-space installations. Contractors use this union to simplify repairs and ensure leak-free performance in fluid, gas, or steam lines. Made from corrosion-resistant 304 stainless steel, it withstands harsh environments and high-pressure applications. Simply thread each end into place and tighten the union nut to create a reliable seal thatโs easy to access and service.
