Flush Face Hydraulic Quick-Connect Fittings
| Series FF interchange with Aeroquip FD49 and Parker FF couplings. Self-cleaning flush face valve design minimizes fluid loss resulting in a cleaner, safer work environment. Automatic, push-to-connect couplings provide high flow and low pressure drop assuring maximum hydraulic tool performance. To reduce the possibility of accidental disconnect, a sleeve lock safety feature requires turning the collar to unlock the coupling. These quick disconnects are made from steel. Conforms to ISO 16028 interchange standard. Operating Pressure: 5000 PSI. |
