KNIPEX Cobra Water Pump Pliers XL 16-Inch — Fast Adjustment & Self-Locking Jaw

Fast, one-handed setup for demanding tasks

Meet the KNIPEX Cobra Water Pump Pliers XL, a 16-inch tool designed to speed up gripping work. Instead of test-fitting openings, you place the upper jaw on the workpiece, press the quick-adjustment button, and bring the lower jaw into position. The result is swift, repeatable sizing with less guesswork on plumbing, automotive, or general assembly tasks.

The design offers 30% more capacity than a conventional pipe wrench, enabling a firm grip on larger nuts and pipes. The teeth act against rotation, creating a self-locking action that resists slipping under load. A pinch guard helps keep fingers safe while you maneuver in tight spaces.

Versatile gripping for round, square, and hex shapes

The optimized jaw geometry handles a variety of cross-sections with confidence. A robust box-joint construction provides high stability and smooth operation, helping you stay productive during busy days.
