Connect Under Pressure Hydraulic Quick Couplers | Parker 6100 Series

Parker 6100 Series Hydraulic Couplers Key Features

  • The connection indicator, a Parker innovation, serves as a visual check for complete connection of the 6100 coupling. It helps prevent premature failures and leaks. It assures that the connection is complete and the valves fully open, eliminating unnecessary flow restriction.
  • The Parker heavy-duty wing nut is ruggedly built-specifically to withstand the hammer blows commonly used to tighten and loosen this coupler.
  • The flange is designed to give a positive “no-slip” bulkhead mounting to reduce downtime.
  • The bonded valve seal permits full pressure connect and disconnect—without seal washout.
  • The flush face valve keeps air inclusion and spillage to a minimum.
  • Corrosion resistant brass body makes this coupling compatible with a broad range of media and provides versatility.
