Air line coupling with low pressure loss and high flow rate

  • The flow rate is increased by up to 40% more than that of conventional Cuplas.
  • During connection and disconnection, the valve is closed, enabling connection/disconnection under zero line pressure.
  • When the sleeve of socket is returned to its original position, the purge mechanism releases the residual air pressure in the plug, eliminating an unpleasant popping noise and a hose whip back motion on disconnection.
  • Built-in sleeve lock mechanism prevents accidental disconnection of Cuplas, assuring safe operation.
  • The valve can be opened and closed while the socket and plug is connected.
  • The weight is reduced by 30 to 45% compared with that of conventional Cuplas.
