In which environment should flared fittings not be used?

Flaring fittings are specifically designed to provide a secure and leak-free connection in various applications, typically involving piping and tubing. However, their performance can be significantly affected in environments with high levels of vibration. The vibrations can lead to the loosening of the fittings over time, increasing the risk of leaks and reducing the reliability of the connection. This is particularly critical in applications where fluid integrity is essential for safety or operational efficiency.

In contrast, while dirty, hot, or cold environments can present their own challenges, they do not inherently compromise the structural integrity or functionality of flared fittings in the same way that high vibration does. For example, contamination might necessitate more frequent maintenance or cleaning, extreme temperatures might require fittings made of specific materials, but these scenarios do not inherently undermine the capability of the flared fitting itself. In environments characterized by significant vibration, the mechanical stress placed on the connections can lead to premature failure or loosening, which is why using flared fittings in such conditions is not advisable.
