Alligator Water Pump Pliers

The Knipex Alligator® Water Pump Pliers 12″ (8802300) are professional-grade adjustable water pump pliers engineered for secure and efficient gripping of pipes, fasteners, and other rounded or flat components. Featuring a slender head and joint area that provides excellent access in tight spaces, these pliers use a box-joint design with a double guide to deliver high stability and leverage. The jaws include specially hardened serrated teeth (approximately 61 HRC) that bite into the workpiece for a reliable, slip-resistant grip, while the self-locking geometry means the tool holds onto pipes and nuts under load without the user having to maintain excessive handle pressure. With nine adjustment positions in the opening slot, the pliers offer roughly 30 % more gripping capacity than conventional water pump pliers of similar size and can handle pipe diameters up to around 70 mm (2 3/4″) with ease. Multi-component comfort grips enhance handling and reduce fatigue during repetitive use, and a pinch guard helps protect fingers during operation. Forged from durable chrome vanadium electric steel with a black phosphate-treated finish, this 12-inch Alligator tool is robust and suited for professional plumbing, mechanical maintenance, and general repair tasks.
