Knipex 8701180SBA 7 1/4" Cobra® Water Pump Pliers

The Original High-Tech Water Pump Pliers.

The Knipex 8701180SBA Cobra eliminates the time-consuming process of test-adjusting the correct opening size. Simply position the upper jaw on the workpiece, push the button, and close the lower jaw for a perfect fit every time. Its compact 7 1/4" design makes it ideal for working in confined spaces, yet it maintains a powerful gripping capacity for pipes up to 1 1/2 inches and nuts up to 36 mm.

Designed with induction-hardened teeth (approx. 61 HRC), these pliers offer high wear resistance and a stable grip that literally "bites" into the workpiece. The self-locking mechanism ensures that once the pliers are set, they stay locked, requiring minimal hand force and preventing accidental slipping that can lead to injuries or stripped fasteners.

Key Performance Features:

• Push-Button Fine Adjustment: 18 different positions allow for optimum adaptation to various workpiece sizes and a comfortable handle width.
• Self-Locking Technology: Effortless work on pipes and nuts with no slipping off the workpiece.
• Box-Joint Design: High stability due to a double-guide system that prevents the tool from twisting under heavy loads.
• Induction Hardened Teeth: Specialized hardening process ensures a secure, long-lasting bite with extremely low wear.
• Built-in Pinch Guard: Engineered to prevent the operator's fingers from being pinched during use.
• Chrome Vanadium Steel: Forged and multi-stage oil-hardened for industrial-grade durability.
