CAP Caterpillar 077-3951

The Hydraulic Tank Breather Filler Cap is a dual-purpose component that seals the hydraulic reservoir while permitting controlled airflow. It prevents contaminants like dust, dirt, and moisture from entering the tank during operation and filling, ensuring hydraulic fluid purity. Integrated with a breather element, it allows the reservoir to breathe as fluid levels change due to thermal expansion. This prevents vacuum buildup that seals and affects system performance.

Attributes:
• Reduces risk of spills during filling.
• Maintains hydraulic fluid cleanliness by blocking contaminants.
• Aids in maintaining proper fluid volume and level.

Applications:
The Hydraulic Tank Breather Filler Cap is mounted at the top of the hydraulic reservoir and seals the reservoir while allowing filtered airflow, preventing pressure imbalance and contamination during fluid level changes.
