What could be the consequence of using incorrect fittings on fluid lines?

Using incorrect fittings on fluid lines can lead to potential leaks or system failures, which is a significant concern in hydraulic and pneumatic systems. When the fittings do not match the specifications required for the fluid line, it can create improper seals or connections. These issues may allow fluid to escape, resulting in leaks that not only waste resources but can also lead to hazardous conditions depending on the nature of the fluid being transported. Additionally, such leaks can cause damage to surrounding components or systems, leading to wider operational failures and safety risks. Ensuring that the appropriate fittings are used is crucial for maintaining the integrity and reliability of fluid systems.
