Quick Disconnect Couplings

Quick disconnect couplings allow a hydraulic or pneumatic line to be separated and reconnected in seconds without tools. Most models carry an automatic shut-off valve in both halves, preventing fluid loss and air ingress when the connection is broken. They are essential on machinery attachments, tool and die changes and test benches. Selection should consider nominal size, working pressure, coupling profile (ISO 7241 A/B, ISO 16028 flat face), body material and fluid compatibility together — different profiles will not mate with one another.
