Flat Face Hydraulic Couplings – Stucchi FIRG Series (ISO 16028)
The Stucchi FIRG series of flat face hydraulic couplings is designed for clean, efficient, and reliable connections in high-pressure hydraulic systems. Suitable for construction, agricultural, and plant machinery, these couplings are widely used where reducing fluid loss and preventing contamination is essential.
Stucchi has been a leading manufacturer of quick couplings and hydraulic connection solutions since 1960. The FIRG series, originally developed in 1983, set the benchmark for flat face coupling design and became the foundation for the ISO 16028 international standard for interchangeability.
