What is the role of seals in a hydraulic system?

Seals play a critical role in hydraulic systems by preventing fluid leakage and maintaining a tight seal within components. This is essential for ensuring that the hydraulic fluid remains under pressure, which is required for the proper operation of the system. Leaks can lead to a decrease in system performance, inefficient operation, and possible damage to components due to fluid loss.

By effectively sealing joints and interfaces, seals help maintain the integrity and efficiency of the hydraulic circuit. This contributes not only to the smooth operation of hydraulic machinery but also ensures safety by minimizing the risk of fluid escaping into the environment. Proper sealing is fundamental to preserving the pressure and volume of hydraulic fluid needed for actuation and control tasks in hydraulic systems.
