Hydraulic quick coupler FLV series

Product overview
This series combines the advantages of flat-face screw coupling technology with an extremely compact and robust design. Ideal for applications requiring a flat-face connection where residual pressures are negligible. MATE 1000 (ZnNi) plating ensures enhanced corrosion resistance. Female coupler bodies allow panel installation.
