Kopplingsrör are commonly found in a wide variety of systems, including plumbing, hydraulic systems, pneumatic systems, and industrial process piping. They are essential for assembling complex piping networks, allowing for flexibility in design and ease of maintenance or repair. By using kopplingsrör, sections of pipe can be replaced or extended without needing to replace the entire length of tubing. The materials used for kopplingsrör vary based on the intended use, ranging from metals like steel and brass for high-pressure applications to plastics for less demanding environments. The integrity of the connection is crucial to prevent leaks and ensure the efficient and safe operation of the system.
