General Features

General Features

N/A Connectable under pressure ARGUS QG flat face quick release couplings are used for quick coupling and uncoupling of hydraulic lines. During the coupling action in zero or low-pressure ranges, valves that release or block the flow are automatically activated. The QG flat face quick release coupling, formed by a coupling plug and a coupling socket, is coupled by pushing on a sleeve. This guarantees a flush connection between the two coupling halves. The sleeve is designed to be moved in the relevant direction for disconnecting or connecting the coupling halves.
  • Connectable under pressure with patented system
  • Low effort to connect under pressure
  • Robust, compact and light weight
  • Low leak-oil rates, eco-friendly
  • Low pressure drop
