Couplings are used to connect two sections of pipe or tubing, allowing fluid or gas to pass through without interruption. Available in several designs, including compression, slip, and welded couplings, these fittings offer a simple yet effective solution for various applications. The main advantage of couplings is their ability to create secure connections while enabling ease of maintenance. They are commonly used in plumbing, gas, and water supply systems, as well as in industrial applications such as mining, construction, and oil & gas pipelines. Couplings are available in a wide range of materials to match the specific requirements of the system, such as brass, stainless steel, or carbon steel.
