87 01 Cobra Pipe Wrench Water Pump Pliers

The Knipex 87 01 Cobra XL Pipe Wrench Water Pump Pliers are high-capacity gripping pliers designed for plumbers, heating engineers and maintenance professionals working with large diameter pipes and nuts. These professional-grade water pump pliers combine the gripping capacity of a traditional pipe wrench with significantly reduced weight, making them ideal for overhead work and extended use. The innovative push-button adjustment system allows fast, precise positioning directly on the workpiece, with 27 adjustment positions providing fine control for different pipe diameters and nut sizes. The box-joint design delivers exceptional stability through double guide construction, whilst the self-locking action on pipes and nuts eliminates slipping and reduces the hand force required during operation. Built with hardened gripping teeth rated at approximately 61 HRC, these Cobra XL pliers deliver outstanding wear resistance and secure grip on both smooth and textured surfaces. The integrated pinch guard protects operators' fingers from being trapped during adjustment, enhancing safety during fast-paced installation and maintenance work. Suitable for pipes up to 90mm diameter and nuts up to 95mm (3 1/2 inches), these pliers are particularly effective for radiator valves, large compression fittings and general pipework applications.
