Adjust directly on the component using slide function
The benefits of working with the Knipex Cobra are plain to see: these water pump pliers are light and stable, thanks to the unique QuickSet technology can be adjusted as quick as a flash on the component and are self-locking on pipes and nuts. The QuickSet function supplements all proven properties of the Knipex Cobra, adding a slide function for easier working in very confined and inaccessible places.
Grip quickly, adjust finely
For pipes, nuts, sleeves, for various kinds of components: slide the Knipex Cobra QuickSet open completely, place the upper jaw on the component and push the lower handle of the pliers up the component. The spring-loaded hinge bolt locks securely into place and can only be moved again by pressing the QuickSet button. Thanks to the 25-fold fine adjustment, the Cobra QuickSet can be ideally adjusted to different sizes of the component. This fine adjustment also makes sure that the distance to the handles remains hand-friendly for every opening width.
The Knipex Cobra QuickSet clamps onto the component securely by itself thanks to the jaw geometry developed by Knipex. This means the user can put all energy into the desired movement without pressing the pliers handle together – and thus without energy loss: round components can be turned, bolted connections tightened and released.
Tough and strong
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 when under strain. The handles stabilise each other in the joint.
