Stäubli developed 3-in-1 active safety to eliminate the risk of violent hose ejection under pressure. With this technology, RSI quick couplings provide a completely safe solution to operators’ most demanding needs. More ergonomic than quick connect fittings, the RSI quick release coupling offers you a real efficient solution for the connection of your pneumatic circuits. The RSI compressed air connectors conform to ISO 6150 C series for connection plugs. ISO 4414 for disconnection backlash prevention..
