For enhanced control, the W 108 8+1 Underwater Fluidic/Pneumatic circular connectors supports shut-off valve configurations, allowing fluid flow to be automatically blocked upon disconnection. This prevents backflow and contamination during underwater maintenance or hot-swap operations.
Max airflow: 210 L/min
Max water flow: 4.2 L/min
This makes it an ideal solution not only for instrumentation panels but also for connectors for marine and underwater applications where rapid connection/disconnection without leaks is critical.
The underwater fluidic circular connector is widely used in:
Underwater drones and ROVs (Remotely Operated Vehicles)
Deep-sea scientific equipment
Submersible pumps and actuators
Shipboard pneumatic systems
Oil and gas inspection probes
Industrial robotics with combined air/electric tools
All these fields benefit from the durable screw-lock mechanism that ensures high retention force. As a result, the High water pressure screw locking connectors format supports extreme operating conditions without compromising sealing or electrical safety.
