FIRG

“FIRG” is the “original one” of the flat face coupling series. Created in 1983, the “FIRG” series has represented a great innovation in the quick couplings field. Used in a wide range of hydraulic applications, the “FIRG” series over time has become the leading series for the realization of ISO 16028 interchangeability. Based on the durable performance and many benefits the series offers, “FIRG” series is most frequently used and approved in the world-wide hydraulic equipment manufacturer’s market. It finds approval in all the applications where fluid loss and contamination of the hydraulic circuit needs to be eliminated.

BENEFITS
  • Flat face is easy to clean, reducing the inclusion of contamination inside the hydraulic circuit.
  • Minimal fluid loss during disconnection, reducing fluid loss to the environment.
  • Minimal air inclusion during connection / disconnection, enhancing correct function of the circuit.
  • Linear flow reduces internal turbulence and pressure drop maintaining circuit efficiency.
  • Good resistance at impulse pressures.
  • Compact slim design.
  • Safe and simple to use.
