Klein Tools Cobra Water Pump Pliers 87 01 250 10-Inch

Professional grip for pipe and nut work

The KNIPEX Cobra water pump pliers deliver 10-inch leverage with a curved jaw that self-locks on pipes up to 2 inches and nuts up to 1 inch. Seven jaw positions and a push-button adjustment let you set the opening directly on the workpiece without trial and error. Induction-hardened teeth at approximately 61 HRC resist wear while maintaining reliable grip.

Sustained hold without re-tightening

The box-joint design with double guide keeps the jaws aligned under continuous torque so the setting does not drift during extended fastening or loosening tasks. Self-locking action reduces the hand force needed to maintain pressure on round or hex surfaces. A built-in pinch guard prevents finger injuries when the handles close under load.

German-made durability for daily use

Forged steel handles and a reinforced neoprene rubber strap withstand repeated industrial cycles while the reliable hinge-bolt catch eliminates unintentional shifting. The 25 adjustment positions accommodate a wide range of fastener sizes across plumbing, HVAC and maintenance jobs. Compact 3.2 by 5.9 by 24.9 centimeter profile fits standard tool bags and belts.
