A fitting designed to create a leak-tight seal on a flared tube end is required. This type of connection employs a 45-degree flared end on the tubing which is then compressed against a mating fitting also machined with a 45-degree inverted flare. The male component typically has a threaded nut that screws onto the female fitting, drawing the flared tube against the inverted flare seat. This mechanical connection provides a robust and reliable seal suitable for high-pressure applications. An example involves connecting hydraulic lines in automotive braking systems or fuel lines in aircraft engines.
The utilization of flared fittings ensures a secure, metal-to-metal seal, eliminating the need for sealing compounds which can degrade over time. This contributes to the longevity and reliability of the connected system, reducing the risk of leaks and subsequent system failures. Historically, such connections were developed to address the shortcomings of compression fittings in demanding applications, offering a superior alternative in environments subject to vibration, temperature variations, and pressure fluctuations.
