Knipex Cobra High-Tech Water Pump Pliers 300mm

The KNIPEX Cobra 87 01 300 SB is a 300 mm water pump plier with improved gripping capacity and reduced weight compared to comparable pipe wrenches. It can grip pipes up to 2 3/4 inches (Ø70 mm) and nuts up to 60 mm, while weighing about 0.53 kg. The design features push-button adjustment on the workpiece, enabling quick, fine-tuned sizing without presetting. The tool is self-clamping on pipes and nuts for reliable, slip-free operation and is built with a box-joint structure for high stability. Its jaws use hardened teeth for high wear resistance and stable gripping, and the pinch guard helps protect fingers during use. The Cobra is forged from chrome vanadium electric steel and oil-hardened, with a plastically coated handle for comfortable use. It conforms to DIN ISO 8976 and offers a generous gripping capacity in a compact 300 mm form factor suitable for a plumber’s toolkit.
