What is a primary reason for choosing the correct seals in a hydraulic system?

Choosing the correct seals in a hydraulic system is essential primarily due to the need for chemical compatibility. Hydraulic fluids can vary significantly in their chemical composition, and if the seals used in the system are not compatible with these fluids, they can degrade over time, leading to leaks and system failures. Chemical incompatibility may cause seals to swell, harden, or become brittle, compromising their effectiveness.

When seals are properly selected based on their ability to withstand the specific chemical properties of the hydraulic fluid, it ensures they will perform effectively throughout their intended lifespan. This maintains the integrity of the hydraulic system, prevents contamination of the fluid, and ensures safe and efficient operation.

While maximizing fluid flow, maintaining operational pressure, and reducing noise levels are important aspects of hydraulic systems, they are secondary in importance when compared to the fundamental requirement of ensuring that seals can handle the specific chemicals involved. Only when seals are chemically compatible can the system function without significant risk of failure.
