The “FIRG-Q” flat-face couplings series is the solution for mildly corrosive environments and/or for relatively corrosive fluid transfer (ex.: sweet water, water and glycol etc). Products are manufactured in carbon steel and treated with special nitriding and oxidation treatment. The internal valve material is stainless steel AISI303 and can be supplied with a variety of seals for fluid compatibility and operating temperature requirements. The flat face design eliminates leakage during connection-disconnection and reduces contamination in the circuit. The combined features of the flat face design with greater resistance to corrosion makes “FIRG-Q” series ideal for several applications, mainly in the industrial field.
- 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.
- Superior corrosion resistance compared to zinc plating in specific corrosive environments.
- Good resistance at impulse pressures.
- Compact slim design.
- Safe and simple to use.
