- Functions
1.Leak-Free Hydraulic Transmission
The assembly uses precision-machined sealing surfaces and durable O-rings/gaskets to prevent hydraulic fluid leakage—critical for maintaining system pressure, reducing fluid waste, and avoiding environmental contamination.
2.Rugged Durability
The steel body is heat-treated for impact resistance and wear resistance, making it suitable for harsh environments (e.g., construction sites with debris, agricultural fields with dust/mud). It withstands vibration and mechanical stress during equipment operation.
3.Easy Installation & Maintenance
Threaded models feature standardized SAE threads for compatibility with ’s original hydraulic ports, enabling direct replacement without modifying the system.
Quick-disconnect variants allow tool-free hose changes, saving time during maintenance or attachment swaps (e.g., switching between excavator buckets and breakers).
4.Pressure & Temperature Resilience
Designed to handle hydraulic systems’ high operating pressures and temperature fluctuations, it avoids seal degradation or body deformation under extreme conditions—ensuring long-term reliability.
