Flush Face Screw Type Couplings (FSI-LS)

Flush face screw type couplings (FSI series) are used in a wide range of industrial markets when connecting and disconnecting is needed. With our color bands our couplings are easy to see at a distance creating a mistake proof system.

  • High-tech Z-786 anti-corrosion plating – salt spray tested for 700 hours before any appearance of surface red rust
  • Connect and disconnects by hand up to 4,400 PSI working pressure
  • Seal blowout resistant to 4,400 PSI when connecting or disconnecting with residual pressure
  • Flat face design eliminates spillage upon disconnection
  • Color bands offered in 10 different colors
  • Sleeve lock design helps from prematurely disconnection in heavy impulse applications
