These light and stable high-tech water pump pliers can be adjusted as quick as a flash thanks to the unique QuickSet technology, e.g. to pipes, nuts and pipe couplings. QuickSet means: slide pliers right open, place top jaw on the component, push the lower handle up to the component and press the pliers. The spring-loaded hinge bolt locks securely into place. It can only be moved again by pressing the QuickSet button. Thanks to the jaw geometry developed by Knipex, the pliers hold pipes and nuts with a self-locking mechanism. The QuickSet function supplements all proven properties of the Knipex Cobra by adding a sliding function. Thanks to the QuickSet, it is also possible to work in confined, poorly accessible areas. Immediately on pressing the pliers, the user can turn his manual force into the desired movement of the component because he does not need to press the handle tightly together. Thanks to the 25-fold fine adjustment, the Cobra QuickSet can be ideally set to different sizes of component, keeping the distance of handles hand-friendly whatever the opening width. We forge the Cobra QuickSet from chrome vanadium steel, and use a multiple stage hardening process to give it the ideal balance between hardness and toughness. This makes it extremely durable. To achieve a lasting secure bite on the work component, we use high-frequency current to bring the gripping teeth to a hardness of approx. 61 HRC. The Cobra QuickSet is further stabilised by the box joint design. Unlike pliers with mounted joints, no tilting forces arise here when under strain. The handles stabilise each other in the joint.
