Operation Principle
This coupling incorporates a locking collar and internal poppet valve within a rotating swivel body. Inserting the matching male plug retracts the collar and opens the valve, allowing fluid to pass through. When disconnected, the valve closes automatically to prevent leakage and keep the system clean. The swivel joint allows the hose to rotate freely without stressing the connection. This tool-free design enables fast, safe, and low-maintenance operation even under pressure.
