Excavators can not avoid high humidity during the application, and there is always a risk of fluid leakage in hydraulic cylinders. There are many reasons why cylinder seals fail. But most of them are unavoidable, such as constant exposure to sunlight or extreme heat from heavy vehicles. So, the only way to ensure smooth operation is to perform regular maintenance and replace damaged seal kits immediately.
