Knipex Cobra Hightech Water Pump Pliers are self-locking on pipes and nuts with no slipping on the workpiece The Knipex 8702250SB (carded) Cobra Hightech Water Pump Pliers are 250mm in length with a capacity for nuts of 46mm and pipes 50mm. The benefits of working with the Knipex Cobra are plain to see. These 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, they can be very easily transported and used in confined spaces. 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 Cobra 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 grip width. 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. 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.
