One of the critical challenges in hydraulic seal design is ensuring that they maintain their integrity under varying operating conditions. High pressure and temperature fluctuations can lead to wear and tear, potentially compromising the seal's effectiveness. Therefore, manufacturers often incorporate design features that enhance durability, such as grooves and contours that improve sealing performance. Regular maintenance and inspection are also essential to identify signs of wear or degradation, allowing for timely replacement and preventing costly downtime.
3. Pressure Maintenance In many applications, oil seals are designed to maintain pressure within a system. By preventing the exit of oil and the entrance of contaminants, they help in sustaining the necessary pressure levels for optimal operation. This function is especially important in hydraulic systems, where pressure plays a critical role in performance.

In contrast, unibody construction integrates the frame and body into a single unit. This design is commonly found in sedans, crossovers, and many modern vehicles. The unibody structure typically provides better fuel efficiency and handling characteristics due to its lighter weight and improved rigidity. However, repairing a unibody vehicle may be more complicated, as damage to the body can compromise the frame's integrity.
