Product Info

Water pump pliers Cobra®...matic

The KNIPEX Cobra..matic water pump pliers is a highly functional tool characterized by automatic adjustment via a push button, which significantly simplifies handling. This plier allows one-handed operation and adjusts directly on the workpiece, making it particularly efficient and user-friendly.
The integrated spring, which is protected in the handle, allows the pliers to automatically close, while the spring-loaded pivot bolt prevents secure and unintended adjustment. With a 25-fold fine adjustment, the pliers can be optimally adjusted to various sizes of workpieces, making it versatile.
Thanks to the through-joint, which has more stable properties compared to laid-on joints, a higher load capacity without tilting forces is achieved. The Cobra..matic is made of chrome-vanadium steel and has a polished surface. Its gripping surfaces are specially hardened (61 HRC), ensuring a durable and secure grip.
The dimensions of the pliers are 250 mm in length, 48 mm in width, and 14 mm in height, with a weight of 335 g. It can grip pipes up to a diameter of 2 inches and nuts up to a diameter of 46 mm.

Water pump pliers Cobra...matic

The high-tech water pump pliers - quick access, fine adjustment

The good reasons for using the Knipex Cobra can be felt in the hand when working: These water pump pliers are light and stable, can be quickly adjusted to the workpiece at the touch of a button and are self-clamping on pipes and nuts.

For pipes, nuts, sockets, for a wide variety of workpieces: apply the Knipex Cobra quickly and precisely with a flick of the wrist. The spring-loaded hinge pin engages securely without moving unintentionally. Thanks to the 25-position fine adjustment, the Cobra can be optimally adjusted to different workpiece sizes. This fine adjustment also ensures that the distance between the handles remains hand-friendly at any opening width.

Resilient and strong

The Knipex Cobra is additionally stabilized by the box joint. In contrast to pliers with surface-mounted joints, no tilting forces occur here under load - the legs of the pliers stabilize each other in the joint.

Self-clamping ensures high efficiency

Thanks to the jaw geometry developed by Knipex, the Knipex Cobra clamps itself to the workpiece. This allows the user to apply force to the desired movement without pressing the pliers legs together - i.e. without loss. Round workpieces can be turned and screw connections tightened and loosened.

Knipex Cobra: many manufacturing steps for high tool quality

We forge the Knipex Cobra from chrome vanadium steel and use a multi-stage hardening process to give it the optimum balance of hardness and toughness. This makes them highly resilient. For a permanently secure “bite” on the workpiece, we also use high-frequency current to bring the gripping teeth to a hardness of approx. 61 HRC.

Professional users expect tool quality that will last for many years of hard use. We develop and manufacture our pliers for the most demanding users imaginable: tradesmen. Every pair of Knipex pliers is manufactured to the highest standards and with the best materials. A purchase for many years of use in assembly, on construction sites, in production and in the workshop.
