Flared Tube Fittings

Flared tube fittings are a type of compression fitting commonly used in fluid systems to connect and seal tubing. They are designed to provide a reliable and leak-free connection between tubes or hoses, particularly in high-pressure applications. Flared tube fittings are widely used in industries such as automotive, aerospace, hydraulic systems, and refrigeration.

The primary feature of flared tube fittings is the flared end on the tubing. This flared end creates a mating surface with the fitting, allowing for a strong and secure connection. The fitting itself consists of three main components: the nut, the sleeve, and the body.

The flared tube fitting assembly process involves several steps. First, the tubing end is cut squarely and deburred to ensure a clean and smooth surface. Then, a flaring tool is used to create the flared end, which typically has a 45-degree angle. The nut and sleeve are then slid onto the tubing, followed by inserting the flared end into the fitting body.

During assembly, as the nut is tightened, it compresses the sleeve onto the flared end of the tubing. This compression action causes the sleeve to bite into the tubing, creating a tight seal. The flared end of the tubing also makes contact with the conical seat inside the fitting body, further enhancing the seal’s integrity.

Flared tube fittings offer several advantages. They provide a robust connection that can withstand high pressures and vibration, making them suitable for demanding applications. The flared connection also offers resistance to pull-out forces, enhancing its reliability. Additionally, flared tube fittings can be easily disassembled and reassembled, allowing for maintenance and repairs without needing to replace the entire fitting.

Benefits of Using Flared Tube Fittings:

Flared tube fittings are commonly used in high-pressure applications, especially in hydraulic and pneumatic systems. Here are some of the benefits of using flared tube fittings:

1. Reliable Seal: The 37-degree flare fitting design provides a metal-to-metal seal that is highly dependable. This ensures a strong, leak-proof connection.

2. Reusable: Unlike some other fittings that might be single-use, flared fittings can often be disassembled and reused, which can save costs in the long run.

3. Versatility: Flared fittings are suitable for a wide range of materials, including hard materials like stainless steel, making them versatile for various applications.

4. High Pressure Handling: Due to their design and the seal they provide, flared tube fittings can handle high pressure, making them ideal for hydraulic applications.

5. Vibration Resistance: The design of flared fittings gives them a degree of resistance to vibration, which can be a critical factor in many industrial applications.

6. Broad Temperature Range: Flared tube fittings can operate effectively across a wide temperature range, making them suitable for systems that undergo temperature fluctuations.

7. Ease of Installation: With the right tools, flared fittings can be relatively easy to install. They do not require soldering, gluing, or welding, which can simplify the installation process.

8. Rotational Alignment: Because of their design, flared fittings allow for the connected tube or hose to be rotated, which can be essential for alignment purposes in certain applications.

9. Durable and Long-Lasting: When installed correctly, flared fittings are known for their longevity and can withstand the test of time even under harsh conditions.

10. Safety: Properly installed flared fittings are highly secure, minimizing the risk of accidental disconnection or leakage that could lead to safety hazards.
