The Knipex Cobra XS is an ultra-compact, professional-grade water pump plier designed for technicians, mechanics, and hobbyists who require high-performance gripping power in extremely tight spaces. Measuring only 100mm, these pliers provide significant mechanical advantage and a surprisingly large gripping capacity, making them an essential addition to any pocket-sized EDC kit. While their small size is ideal for precision tasks, users should note that they are not a replacement for larger pipe wrenches when dealing with high-torque industrial plumbing applications.

The Knipex Cobra XS is rated for pipes up to 28mm in diameter.
While they are very strong for their size, they are not designed for large-scale industrial plumbing tasks that require high torque leverage.
The 100mm Cobra XS features 11 fine adjustment positions.
Yes, they include a built-in pinch guard designed to prevent accidental finger injury during operation.
The gripping surfaces feature special hardened teeth with a hardness level of approximately 61 HRC.
Clean the adjustment mechanism with a solvent to remove dirt and apply a light machine oil to the pivot.
Ensure the hardened teeth are properly seated and apply more force to the handles to engage the self-locking geometry.
These pliers require no complex setup; simply press the adjustment button to slide the jaws to the desired width. To maintain the tool, keep the joint mechanism free of grit and debris. Periodically apply a drop of high-quality machine oil to the joint pivot to ensure smooth operation. Store in a dry environment to prevent surface oxidation. Avoid using the pliers as a hammer or prying tool, as this can misalign the precision-engineered box joint and dull the hardened gripping teeth.
