Operating Principle
The plug features an internal poppet-style valve that remains closed whenever disconnected. Once screwed into the matching ISO‑A socket, locking elements engage and the valve opens to allow hydraulic fluid to flow. As soon as the plug is removed, the valve shuts instantly to prevent leaks or dirt ingress. The threaded interface offers a secure, vibration-resistant fit that avoids accidental decoupling. This design ensures rapid, clean and tool-free operation perfect for demanding industrial or mobile hydraulic use.
