A Threaded Union is a versatile pipe fitting designed to join two pipes while allowing for easy disconnection without cutting or disturbing the system. Unlike a standard coupling, a threaded union consists of three parts: a nut, a male end, and a female end. This design allows the pipes to be connected or disconnected quickly, making it ideal for maintenance, repairs, or system modifications. The internal threads provide a secure, leak-resistant seal without the need for welding.
Manufactured from high-quality materials such as stainless steel, carbon steel, brass, and malleable iron, threaded unions are highly durable, corrosion-resistant, and capable of withstanding high pressure and temperature conditions. Precision-machined threads ensure proper alignment and reliable engagement with standard threaded pipes, ensuring long-lasting performance.
Threaded unions are widely used in plumbing systems, oil and gas pipelines, HVAC installations, fire protection systems, compressed air networks, and industrial process piping. They are suitable for handling water, oil, gas, steam, air, and other compatible fluids. Produced to comply with standard threading specifications such as BSP and NPT, these fittings are compatible with commonly used threaded components.
Available in a wide range of sizes, pressure ratings, and finishes including galvanized, black, and polished options, our Threaded Unions offer a practical, cost-effective, and efficient solution for creating strong, maintainable, and leak-free connections in residential, commercial, and industrial piping applications.
