We are introducing this Hydraulic Tank Vent Cap for 3" Wide Tanks - Replaces ABA-16, ABA16, INDABA16. This hydraulic tank vent cap is engineered for use in heavy-duty trucks, industrial machinery, and mobile hydraulic systems. Designed to maintain clean air exchange within hydraulic reservoirs, it avoids pressure buildup while blocking contaminants that can harm hydraulic components.
Efficient Ventilation Design: This breather cap easily installs on standard hydraulic tank openings. It enables free airflow in and out of the reservoir as hydraulic fluid levels fluctuate, ensuring balanced internal pressure for stable system operation.
High-Performance Filtration: The foam filtration element effectively captures dirt, dust, and airborne particles while allowing air to pass through smoothly. This ensures the hydraulic system stays clean, protecting pumps, valves, and seals from impurity-related wear.
Durable Construction: The vent cap is engineered for demanding environments, It performs reliably in both cold climates and high-heat industrial operations, making it suitable for diverse hydraulic setups.
Optimized Airflow Capacity: It provides efficient air exchange for tanks of various sizes, ensuring smooth operation without vacuum or overpressure conditions.
Compact Fit: This vent cap fits a wide range of liquid transfer and hydraulic tanks measuring 3" wide.
Application: This vent cap is ideal for hydraulic reservoirs used in trucks, trailers, agricultural machinery, and industrial hydraulic systems. It ensures the hydraulic tank breathes properly during fluid expansion and contraction, extending the life of the hydraulic components by avoiding impurities and pressure imbalance.
Compatibility: Compatible with the following brands and their part numbers: Fits American Mobile Power: ABA-16
Fits OE Aftermarket: ABA16, INDABA16

How to Use This
Install the vent cap by threading it securely into the NPT port on the hydraulic tank.
Ensure the foam filter inside the breather cap is clean and seated correctly.
During system operation, the cap automatically allows air exchange while filtering out impurities.
Check periodically to ensure no clogging or damage to the filter element.
Maintenance Tips
Inspect and clean the filter regularly to maintain proper airflow.
Replace the vent cap if the foam element becomes saturated, brittle, or clogged.
Check for leaks around the threaded connection and tighten if necessary.
Avoid painting or blocking the vent openings to ensure proper air passage.
