Knipex Adjustable Water Pump Pliers One Tool, Every Size When you're mid-wrench on a bottom bracket shell or chasing a stubborn hose fitting at the back of a frame, the last thing you want is a slip or a scramble for a different tool. The Cobra Adjustable Water Pump Pliers handle that situation with a push-button jaw adjustment that sets directly on the workpiece and locks without drifting.

A box-joint construction keeps the head stable under load, and a pinch guard protects your fingers on fast adjustments. Available in four sizes to cover everything from compact cockpit work to larger shop tasks, these are the pliers most professional mechanics reach for first.
