Knipex 8701250 10″ (250mm) COBRA High-Tech Water Pump Pliers

Patented Push-Button Adjustment. Self-Locking Gripping Power. Induction-Hardened 61 HRC Teeth.

The KNIPEX Cobra 10-Inch Pliers utilize a push-button adjustment and self-locking jaw to grip pipes tightly, offering professional-grade leverage and safety.

The KNIPEX Cobra Water Pump Pliers bring legendary mechanical bite, one-handed sizing agility, and unmatched structural stability directly to your commercial tool belt. Purpose-built to eliminate the slipping jaws of traditional tongue-and-groove pliers, the painful blood blisters from collapsing handles, and the wasted energy of constantly squeezing to maintain a grip, this premium German-engineered water pump plier sets the absolute standard for heavy-duty plumbing and industrial mechanical work. It equips pipefitters, commercial plumbers, automotive mechanics, and heavy equipment technicians with an elite gripping tool optimized to bite into stripped bolts, crank down galvanized pipes, pull heavy cotter pins, and maneuver securely in tight, greasy engine bays.

Exceptional jaw geometry and high-tensile metallurgical strength form the backbone of the KNIPEX Cobra. Forged from high-alloy chrome vanadium electric steel and multi-stage oil-hardened, the specialized gripping teeth are additionally induction-hardened to an incredible 61 HRC. Once the patented push-button box joint is set into one of its 25 fine-adjustment positions, the pliers' self-locking geometry takes over. You simply push down on the top handle and the jaw bites into pipes up to 2 inches (50 mm) or hex nuts up to 1-13/16 inches (46 mm) without slipping, completely eliminating hand strain.

Why the KNIPEX® 87 01 250 Cobra® Pliers Dominate the Trade:

• Self-Locking Jaw Architecture: Once engaged, the jaws bite deeply into pipes and nuts without requiring you to squeeze the handles together, saving massive amounts of hand fatigue.
• 25-Position Push-Button Adjustment: Fine-tunes the jaw opening precisely to the workpiece. Just press the button, slide the jaw, and lock it in for a flawless fit.
• High-Stability Box-Joint Design: Features a double-guided box joint that eliminates the wobbly, twisting action common in cheap slip-joint pliers under heavy torque.
• Integrated Anti-Pinch Guard: The handle stops are engineered to maintain a safe clearance gap when fully closed, entirely preventing painful blood blisters on your fingers.
• Induction-Hardened 61 HRC Teeth: Diamond-hardened teeth pierce through rust, grease, and paint to grab heavily stripped bolts and smooth pipes with zero slippage.
