The high-tech water pump pliers
Grip quickly, adjust finely
The benefits of working with the Knipex Cobra are plain to see: these chrome-plated water pump pliers are light and stable, can be adjusted on the component quickly at the touch of a button and are self-locking on pipes and nuts. With their slim multi-component grips without collar, the Knipex Cobra 87 05 250 can be very easily transported and used in confined spaces. The chrome plating gives the Cobra 87 05 250 particularly good rust protection.
For pipes, nuts, sleeves, for various kinds of components: the professional user applies the Knipex Cobra quickly and accurately with just one hand movement. The spring-loaded hinge bolt locks securely into place without adjusting inadvertently. Thanks to the 25-fold fine adjustment, the Knipex Cobra can be ideally adjusted to different sizes of component. This fine adjustment also ensures that the distance to the handles remains hand-friendly for every opening width.
Tough and strong
The Knipex Cobra 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.
Self-locking mechanism ensures a high degree of efficiency
The Knipex Cobra 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.
Brief overview
Knipex Cobra: several manufacturing steps for high tool quality
We forge the Knipex Cobra 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.
Professional users expect a tool quality that will last for many hard years of work. We develop and manufacture our pliers for the most demanding users imaginable: for craftsmen. Every pair of pliers from Knipex is manufactured to the highest standards using the best materials. A purchase for many years of use during assembly work, on the building site, in production and in the workshop.
