Operation Principle
This female coupling features an internal poppet valve and spring-loaded locking collar. When connected to the matching male plug, the collar retracts and opens the valve, allowing hydraulic fluid to pass. Once disconnected, the valve automatically closes, preventing fluid leakage and keeping the circuit clean. The flat-face seal ensures a clean, drip-free separation even under pressure. This tool-less connection offers fast, safe, and low-maintenance coupling for hydraulic systems.
