Knipex 87 02 250 Cobra® Water Pump Pliers

The Knipex 87 02 250 Cobra Water Pump Pliers is a 250 mm adjustable gripping plier designed for pipes, nuts, and fittings across a wide range of workpiece sizes. A spring-loaded push-button allows one-handed adjustment directly at the workpiece, while the self-clamping jaw geometry grips without slipping under load. The through-bolt joint provides double-guided stability that eliminates the tipping forces common in overlay-joint designs.
