FF90 Series

90-degree flat face couplers made to the ISO 16028 Standard

AKJia’s FF90 Series is designed for use in applications that require a 90° elbow in the hydraulic circuit, such as digger booms. The right-angle design allows for easy mounting without the need for additional fittings, reducing potential leakage paths and cost.

Construction

  • Carbon steel with trivalent plating as default
  • Carbon steel with zinc-nickel plating option (1200 hours with no red rust in salt spray tests
  • Fitted with Nitrile seals – NBR (Viton seals – FKM available)
