The A Premier Series Flat Face ISO 16028 Interchange Couplings offer higher pressure ratings, superior flow characteristics, and lower pressure drops compared to FIRG Series or competitors’ products. Specifically designed for applications needing no-leak performance and the ideal solution for limiting contamination in hydraulic circuits, the non-spill design avoids fluid loss during connection and disconnection. The A Premier is also available in an international version, with British BSP or German DIN port options.
