Which outcome accelerates in hydraulic actuator seals when fluid temperature rises significantly?

💡 Explanation

Increased temperature causes the fluid viscosity to decrease, reducing its lubricating properties; this enables increased friction & wear by boundary lubrication mechanisms, causing accelerated seal degradation because direct contact generates heat and friction, therefore seals fail rapidly, rather than maintaining an effective barrier.
