Flared Tube Unions

Flared tube unions are a type of fitting used in plumbing and hydraulic systems to connect pipes or tubes together securely. They are commonly used in applications where a leak-free connection is required, such as in automotive, aerospace, and industrial systems.The design of a flared tube union consists of two main components: the flared fitting and the flare nut. The fitting has a flared end, which is a cone-shaped expansion at the end of the pipe or tube. The flare nut is a threaded nut that screws onto the fitting, compressing it against the receiving fitting or component.The flared end of the fitting is created by using a specialized tool called a flaring tool. This tool is used to shape the end of the pipe or tube into a 45-degree cone. The cone-shaped flare provides a larger surface area for the seal to be made, ensuring a tight and reliable connection.To assemble a flared tube union, the flared end of one pipe or tube is inserted into the receiving fitting or component. The flare nut is then threaded onto the fitting and tightened by hand or with a wrench. As the nut is tightened, it compresses the flared end of the fitting against the receiving component, forming a seal. This compression creates a strong and leak-free connection between the two parts.One of the advantages of using flared tube unions is their resistance to vibration and mechanical stress. The compression created by the flare nut helps to absorb and distribute forces, reducing the likelihood of loosening or leaking under dynamic conditions.
