KNIPEX Cobra Water Pump Pliers 87 02 250 – Slim, Self-Locking, 25-Fold Fine Adjustment

Fast, precise adjustments with one hand

Meet the KNIPEX Cobra 87 02 250 water pump pliers — a lightweight, highly stable tool designed to grip pipes, nuts, sleeves, and other components with ease. The slim, collar-free grips keep the tool compact and easy to maneuver in cramped spaces while delivering dependable control. This combination of lightness and steadiness makes everyday tasks feel smoother, giving you more confidence on the job.

Push-button adjustment and self-locking grip

A push button on the upper jaw lets you set the opening directly at the workpiece. When you close the lower jaw, the pliers self-lock on pipes and nuts, reducing the need for readjustment and helping you stay focused on the task at hand.

Fine-tuned to handle a variety of sizes

The Cobra 87 02 250 offers 25-fold fine adjustment, allowing you to tailor the grip to different component sizes while keeping a comfortable handle width. This design supports smoother one-handed operation and minimizes hand fatigue during repetitive work.

Durability and stability you can feel

Box joint construction enhances overall stability, preventing tilting under load. The jaws feature special hardened teeth, roughly 61 HRC, ensuring reliable grip when working with round, square, or hex shapes.

Practical benefits in real work

In plumbing, electrical, or HVAC settings, the Cobra clamps securely, enables turning and tightening of components, and supports resistance to slip without frequent readjustment. Its slim profile helps you work efficiently in constrained environments.
