12FFPCUP75UN Eaton FFCUP Series ISO 16028 Connect Under Pressure Flat Face Male Plug 3/4 16f UNF Female SAE J 1926-1 NBR+AU Quick Disconnect Coupling Steel


PRODUCT DESCRIPTION

Eaton FFCUP Series - ISO 16028 Connect Under Pressure Flat Face Plug/Male - Steel - Male Plugs

 

Eaton's FFCUP Series plug/male coupling is an ISO 16028 standard interchange. The flush face design prevents fluid loss on disconnection and air inclusion on connection guaranteeing excellent flow capability. An integrated patented system allows the FFCUP Series plug to be connected to a socket/female half coupling under 350 bar (5075 psi) residual pressure.

See How to Order

Please reference Fluid Compatibility Chart (Both the elastomer and metal must be considered when determining suitability of combination for a coupling)

Connect Under Pressure Operating Guidelines
  • The plug can be connected against 350 bar/5075 psi residual pressure to sockets/females meeting
  • Plug only is under pressure while being connected
  • During the connection phase, the socket must not be under pressure
  • Disconnection under pressure is strictly forbidden
  • Connection under pressure may require a few seconds: the force to connect must be maintained during this lapse of time
