Filling and Ventilating Caps

The oil level in the hydraulic oil tank varies due to temperature changes and hydraulic oil leaks in the hydraulic system. Due to the pressure difference caused by that, the polluted air tries to enter the tank. Filling and ventilation covers are used to prevent polluted air, particles and water from entering the tank from the outside.
