Design and Performance
Fast, Tool-Free Pneumatic Line Disconnection
As a plug-in quick coupling socket, the KD4-1/4-A allows pneumatic lines to be connected and disconnected quickly without tools, speeding up equipment changeovers, maintenance, and hose replacement tasks.
Shut-Off on One Side for Controlled Depressurization
With shut-off functionality on one side, this coupling automatically seals the connected line when disconnected, minimizing air loss and preventing sudden pressure release during disconnection.
High Flow Capacity for Demanding Pneumatic Circuits
With a standard nominal flow rate of 1,260 l/min, this coupling supports higher-flow pneumatic applications, delivering rapid air delivery even in circuits with substantial air consumption.
Compatible with the KS4 Quick Coupling Plug Family
This coupling socket pairs with corresponding KS4 series quick coupling plugs, letting engineers select the matching plug from a broad range of thread and barbed fitting options within the same product family.
Corrosion-Resistant Nickel-Plated Brass Construction
Nickel-plated brass construction provides strong corrosion resistance, supporting reliable long-term operation across a wide -10°C to 60°C ambient temperature range.
