The Knipex 87 02 250 10in cobra water pump pliers are perfect for pipes, nuts, sleeves, other various kinds of components. These water pump pliers from Knipex 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. Due to the 25-fold fine adjustment, the 10in pliers can be ideally adjusted to different sizes of the component and makes sure that the distance to the handles remains hand-friendly for every grip width. The Knipex 87 02 250 features a box joint design; unlike pliers with mounted joints, no tilting forces arise when under strain. To achieve a lasting secure “bite” on the component, a high-frequency current is used on these pliers to bring the gripping teeth to a hardness of approximately 61 HRC. The Knipex 10in cobra water pump pliers are forged chrome vanadium steel and use a multiple stage hardening process to give it the ideal balance between hardness and toughness.
