Union Type Couplings: Description and Applications

Union type couplings are essential pipe fittings designed to connect two pipes securely while allowing for easy disassembly and reassembly. Unlike other permanent joints, union couplings provide a detachable connection, making them ideal for applications that require periodic maintenance, inspection, or replacement. Commonly made from materials like stainless steel, brass, and iron, these couplings are versatile and highly durable, capable of withstanding various pressures and temperatures depending on their construction and material.

Union couplings are composed of three parts: two threaded ends and a central nut that tightens to form a sealed connection. This design ensures leak-free operation and minimizes downtime when pipes or components need to be separated. They are used across industries like plumbing, gas, chemical processing, and oil, where secure, removable connections are required.
