• Precise Compatibility: Manufactured strictly to CASE IH original specifications, ensuring perfect alignment with New Holland combine hydraulic systems for stable connections and seamless compatibility.
• Safety Locking: Features an integrated locking mechanism to prevent accidental disconnection during operation due to vibration, ensuring operational safety.

Primarily used in the hydraulic systems of New Holland combine harvesters, it connects hydraulic lines in critical areas such as the header hydraulic drive, conveyor hydraulic control, and steering hydraulic system. Suitable for various operating conditions in agricultural harvesting operations, including crop harvesting scenarios across different terrains such as plains and hills.

1. Which models is the 84435502 hydraulic connector compatible with?
Specifically designed for New Holland Combine Harvesters, it conforms to CASE IH hydraulic system standards. It serves as an OEM replacement for matching hydraulic line interfaces on corresponding models. For specific compatibility, refer to the equipment manual or original manufacturer specifications.

2. What is the maximum working pressure for this connector? What types of hydraulic fluid are compatible?
Maximum working pressure reaches 4000 PSI. Compatible with standard agricultural hydraulic fluids. Any fluid meeting agricultural hydraulic system standards can be used normally, provided it is compatible with the seal material (nitrile rubber).

3. How should this hydraulic connector be properly installed?
Before installation, shut down the machine and relieve pressure. Clean oil residue and debris from the interface, and inspect the seal for integrity. Align and insert the connector; a “click” sound indicates successful locking. After installation, gently pull the hose to test connection stability, preventing disengagement during operation.

4. What should be done if hydraulic oil leakage occurs during use?
First, shut down the machine, relieve pressure, and disconnect the connector. Inspect the seals for aging, damage, or misalignment during installation, and replace them promptly. If leakage persists, check the joint surface for scratches or deformation; replace the entire connector if necessary. Simultaneously, investigate whether the hydraulic system pressure is abnormal.

5. What causes difficulty during connection/disconnection? How to resolve?
Common causes include: unrelieved hydraulic pressure, contaminants in the interface, locking mechanism jamming, or seal expansion. Solutions: First relieve pressure per specifications; clean the interface and locking mechanism with a solvent; inspect seal condition and replace if aged; if components are worn or deformed, replace the connector promptly.

6. What advantages does this connector offer compared to original equipment manufacturer (OEM) parts?
As an OEM replacement, it precisely matches equipment interfaces without requiring additional modifications. Premium steel construction and precision sealing ensure leak resistance and durability. The quick-connect/disconnect design saves operation time, while the integrated locking mechanism enhances operational safety. It offers superior cost-effectiveness compared to some non-standard aftermarket parts.

7. Can connection or disconnection be performed under pressure?
Not recommended. Operating under pressure may cause interface leaks, component damage, and potential safety hazards. Always shut down the machine first, release hydraulic line pressure via relevant control elements, then perform connection or disconnection.

8.Do seals require periodic replacement? What is the recommended replacement interval?
Yes. Seals are wear parts that degrade over time due to prolonged exposure to hydraulic fluid and operating conditions. Replacement is recommended every 500-800 operating hours or when seal performance deteriorates. Intervals should be shortened under severe operating conditions.
