Slip-joint pliers Knipex Cobra 87 03 125

The Knipex Cobra® Slip-joint pliers (model 87 03 125) are compact, adjustable water pump pliers designed for gripping pipes, nuts and other round or flat workpieces. With a total length of 125 mm and a lightweight construction (85 g), these pliers combine maneuverability with robust jaw design. The self-locking jaw geometry and push-button quick adjustment let you set the jaw width directly on the workpiece without time-consuming presetting, ensuring fast and precise gripping of components up to the specified sizes.

Advantages

These Knipex Cobra pliers feature quick push-button adjustment for one-handed size changes and a self-locking profile for secure gripping without slipping. Their compact 125 mm length and low weight make them easy to handle in confined spaces, while hardened gripping surfaces provide reliable contact on pipes up to 25 mm diameter and nuts up to 27 mm across flats. The tool is corrosion-resistant and built for repeated professional use.

• Tightening and loosening nuts and bolts (up to 27 mm across flats)
