FIRG is the "original one" of the flat face couplings 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 FIRG series is most frequently used and approved in the worldwide hydraulic equipment manufacturer’s market. It finds approval in all applications where fluid loss and contamination of the hydraulic circuit needs to be eliminated.
