Flat Face Screw Couplings incorporate all of the benefits from the flat face design, whilst the screw connection strengthens the coupling and eliminates brinelling. Connection and disconnection can be undertaken with pressure in both male and female halves excluding the VFF1 Series. An ideal solution for high pressure pulses and many other applications.
