Cobra XL Pipe Wrench and Water Pump Pliers 400mm Knipex

For extreme physical work on large components

The Knipex 87 01 400 Cobra with a length of 400 mm is one of the biggest models of water pump pliers on the global market; it is the second largest in the Cobra range from Knipex. The benefits of working with these water pump pliers are plain to see. They can be positioned on the component quickly and are self-locking, e.g. on pipes and nuts. With its plastic-coated handles, the Knipex Cobra 87 01 400 sits firmly and pleasantly in the hand. It can be used for professional use on pipes up to a diameter of 3 ½ inches or 90 mm and for nuts with a wrench opening of up to 95 mm.

With self-locking effect and fine adjustment

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 27-fold fine adjustment, the Knipex Cobra 87 01 400 can be ideally adjusted to different sizes of the component. This fine adjustment also ensures that the user is able to find a hand-friendly gripping position for every grip width.

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.

Tough and strong

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.

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.
