Which maintenance practice helps prevent air leaks in pneumatic systems?

Routine tightening of fittings and connections is a critical maintenance practice that helps prevent air leaks in pneumatic systems. Over time, vibrations and pressure fluctuations can cause fittings and connections to loosen. Regularly tightening these components ensures they remain sealed, thereby preventing any potential air loss. This practice is essential because even small leaks can significantly impact the efficiency and performance of a pneumatic system, leading to increased energy consumption and compromised functionality.

While regular hose replacement, annual system overhaul, and using only new components are also important for overall maintenance, they do not directly address the ongoing need to maintain tight seals at fittings and connections, which is crucial for leak prevention.
