Flared Bulkhead Unions for 37° Flared Tube Fittings

Flared Bulkhead Unions

A Flared Bulkhead Union is a specific type of fitting used primarily in fluid and pneumatic systems. Its main function is to facilitate the transition of tubing or piping through a bulkhead (a wall or barrier) while maintaining a sealed connection. The use of flared connections is crucial for preventing leaks, especially in systems that involve high pressures.Flared bulkhead unions are commonly used in various industries, including automotive, aerospace, marine, and hydraulic systems. They are often used in applications involving fuel lines, brake systems, refrigeration, hydraulic power, and other fluid transfer systems.Flared Bulkhead Unions Components:1. Bulkhead Body: This is the main component that passes through the wall or barrier. It has a flared fitting on each end to accept the flared tubing.2. Locknut: This is used to secure the union to the bulkhead. Once the body is placed through the hole in the bulkhead, the locknut is screwed onto the threads of the body from the opposite side, holding the union firmly in place.3. Flared Tubing: Tubing that has been expanded (flared) at the end in order to make a tight seal with the matching flare of the union.

Features of Flared Bulkhead Unions:

Flared bulkhead unions offer several features that make them suitable for various applications. Here are some key features of these fittings:1. Bulkhead Design: Flared bulkhead unions are specifically designed to pass through a panel or bulkhead. This allows for the connection of pipes or tubes on opposite sides of a barrier without compromising the integrity of the panel.2. Flared Connection: These flared bulkhead unions utilize a flared connection system. The pipe or tube end is flared or tapered, which fits into a corresponding fitting with a matching conical seat. When the nut is tightened, it compresses the flared end against the seat, creating a secure and leak-free connection.3. Easy Installation and Disassembly: Flared bulkhead unions are designed for easy installation and disassembly. They typically feature a nut and ferrule system that allows for quick and convenient assembly without the need for specialized tools. This makes maintenance, repairs, and modifications more efficient.4. Leak-Resistant Seal: The flared connection in these unions provides a reliable and leak-resistant seal. When properly assembled, the flared end of the pipe or tube is compressed against the conical seat, creating a tight seal that prevents fluid leakage.5. Material Compatibility: Flared bulkhead unions are available in various materials to ensure compatibility with different fluids and operating conditions. Common materials include brass, stainless steel, and different types of plastic. The material choice depends on factors such as fluid compatibility, pressure, temperature, and environmental conditions.6. Wide Range of Applications: These flared bulkhead unions are used in a wide range of industries and applications, including automotive, aerospace, marine, and hydraulic systems. They are commonly employed in fuel lines, brake systems, refrigeration, hydraulic power, and other fluid transfer systems.7. Pressure and Temperature Ratings: Flared bulkhead unions are designed to withstand specific pressure and temperature ranges. It is essential to select unions that meet the requirements of the intended application to ensure safe and reliable operation.8. Versatility: Flared bulkhead unions are available in various sizes and configurations to accommodate different pipe or tube diameters and connection needs. This versatility allows for flexibility in system design and installation.
