Knipex Cobra Water Pump Pliers - 125mm

These Knipex Cobra 125mm pliers can grip pipes up to 29mm in diameter and nuts up to 27mm across flats.

While highly durable and high-performance for their size, the 125mm model is best suited for precision tasks and work in confined spaces. For very heavy-duty industrial applications with larger fasteners, a larger Knipex Cobra model would be more appropriate.

The self-locking grip firmly holds onto the workpiece without requiring constant pressure from your hand, significantly reducing fatigue and making it easier to work in awkward positions or for extended periods.

Press the adjustment button (located on the side of the pliers) to unlock the jaws, slide them open or closed to fit your workpiece, and then release the button. Ensure the jaws fit snugly for optimal grip.

No, these Knipex Cobra pliers are not insulated for electrical work. Always ensure the power is off when working on electrical components or use appropriately insulated tools.

They are made from high-quality Chrome vanadium electric steel, which is forged and then oil hardened for maximum strength and durability.

No, these are water pump pliers designed for gripping, holding, and turning. They do not have cutting edges and should not be used for cutting wire, as this can damage the jaws.

Ensure the jaws are correctly adjusted to the workpiece size, utilizing one of the 13 fine positions. The self-locking feature works best with a snug fit. Also, check the gripping teeth for any debris or wear that might be reducing friction.

Check the adjustment mechanism for any trapped debris or excessive dirt. Apply a small amount of light machine oil to the pivot point and adjustment slot, then work the mechanism back and forth to loosen it. Ensure the jaws are fully open when attempting to adjust.

Clean the rusted areas with a rust remover or a fine abrasive pad. After cleaning, thoroughly dry the pliers and apply a light protective coat of machine oil, paying special attention to the pivot and jaw areas. Store in a dry environment to prevent future rust.
