General Features

General Features

 N/A ARGUS QS quick release couplings enable oil leak-free connection and disconnection of hydraulic lines. Their robust construction and tested components make them ideally suited for high and intermittent pressure loads. During the coupling action, valves that release and/or block the flow are automatically activated. The QS quick release coupling, formed by coupling plug and coupling socket, is coupled by a screwing action with the hand nut of the plug component.
  • Very low leak-oil rates, eco-friendly
  • Highly robust construction
  • Low pressure drop
  • Locking system for safety purposes
