Flared Tube Large Hex Unions for 37° Flared Tube Fittings

Flared Tube Large Hex Unions

Flared tube large hex unions are a type of pipe fitting used in plumbing and fluid systems to join two sections of flared tubing together. These unions provide a secure and leak-free connection while allowing for easy disassembly and reassembly of the tubing system.The term "flared tube" refers to a type of tubing that has been flared at the end. Flaring involves expanding the end of the tube to create a conical shape. This shape allows for a tight seal when the tube is connected to a fitting. Flared tubing is commonly used in applications where a high-pressure or leak-resistant connection is required, such as in hydraulic and pneumatic systems.A large hex union, as the name suggests, has a hexagonal nut at its center. This nut is typically larger in size compared to standard unions, providing a larger surface area for gripping and tightening the fitting. The hexagonal shape allows for easy installation and removal using a wrench or spanner.The flared tube large hex union consists of three main components: the flared end of the tubing, the union body, and the large hex nut. The flared end of the tubing is inserted into the union body, which contains a cone-shaped seat. The hex nut is then threaded onto the union body, compressing the flared end of the tubing against the cone-shaped seat. This compression creates a tight seal and ensures a secure connection.One advantage of using flared tube large hex unions is their ability to withstand high pressure and vibration. The flared end of the tubing provides a robust connection that is less prone to leaks, even under demanding conditions. Additionally, the large hex nut allows for easy installation and removal, making maintenance and repairs more convenient.Flared tube large hex unions are commonly used in various industries, including automotive, aerospace, plumbing, and fluid power systems. They are compatible with different types of tubing materials, such as copper, steel, and stainless steel, making them versatile for a wide range of applications.

How to Install the Flared Tube Large Hex Unions?

To install a flared tube large hex union, follow these general steps:1. Gather the necessary tools and materials: You will need the flared tube large hex union, the tubing sections you wish to connect, a tubing cutter or appropriate cutting tool, a deburring tool, and a wrench or spanner.2. Prepare the tubing: Cut the tubing to the desired length using a tubing cutter, ensuring clean and straight cuts. Remove any burrs or rough edges from the cut ends of the tubing using a deburring tool.3. Flare the tubing: Using a flaring tool specifically designed for the type and size of tubing you are working with, flare the ends of the tubing. Follow the instructions provided with the flaring tool to achieve the correct flare shape and size.4. Insert the tubing into the union body: Take one of the flared ends of the tubing and insert it into the union body. Ensure that the tubing is fully seated inside the union body, up to the cone-shaped seat.5. Tighten the hex nut: Thread the large hex nut onto the union body, covering the flared end of the tubing. Use a wrench or spanner to tighten the hex nut securely. Be careful not to overtighten, as it may damage the tubing or the union.6. Repeat for the other end: Repeat steps 4 and 5 for the other end of the tubing, connecting it to another section or component as needed.7. Check for leaks: Once the flared tube large hex union is installed, check for any signs of leaks. Apply a suitable pressure test or run fluid through the system to ensure there are no leaks at the connection points.It's important to note that the specific installation process may vary depending on the type and size of the flared tube large hex union and the tubing material being used.
