Knipex 88 01 180 7-1/4″ (180mm) ALLIGATOR Water Pump Pliers Black Metal
The Legend of Grip: Harder Pull, Tighter Bite
The Knipex 88 01 180 Alligator® Pliers are the industry standard for professional tradespeople who can’t afford for their tools to slip. Engineered with a unique self-locking geometry, these pliers stay securely clamped onto pipes and nuts once engaged—meaning you don't have to squeeze the handles together with all your might. The more force you apply to the turn, the tighter the Alligator bites.
Constructed from chrome vanadium heavy-duty steel and oil-hardened, these pliers feature induction-hardened teeth (approx. 61 HRC) that stay sharp through years of grueling use. With a 9-step adjustment positioning, the 180mm (7-1/4") Alligator provides 30% more gripping capacity than standard pliers of the same size.
Why the Alligator® Series Outperforms the Rest:
- Self-Locking Action: Once set, the pliers lock onto pipes and nuts, requiring zero hand strength to maintain the grip—just push and turn.
- 9-Position Adjustment: Fine-tuned adjustment for a perfect fit on workpieces up to 1-1/2" (42mm) in diameter.
- Box-Joint Design: Double-guide construction provides extreme stability and prevents the pliers from twisting under heavy loads.
- Induction-Hardened Teeth: High wear resistance ensures a reliable bite for the life of the tool.
- Slim Profile: The thin head and joint area allow you to reach into tight spaces where bulky wrenches won't fit.

Frequently Asked Questions
+ How does the "Self-Locking" feature work?
Knipex Alligator pliers use a specialized jaw geometry. Once you place the jaws on a pipe or nut and apply pressure in the direction of the turn, the teeth dig in and the pliers hold themselves in place. You don't have to waste hand energy squeezing the handles together to maintain the grip.
+ What is the difference between the Alligator and the Cobra?
The Alligator features a traditional manual slip-joint adjustment (9 positions), while the Cobra uses a push-button fine adjustment. Many pros prefer the Alligator for its simplicity, speed of manual adjustment, and classic robust feel.
+ Will these teeth wear down over time?
Knipex induction-hardens the teeth to approximately 61 HRC. This is significantly harder than the metal found in standard hardware-store pliers, ensuring they maintain their "bite" even after years of turning hardened steel pipes.
+ Are the handles insulated?
No. The plastic-dipped handles are designed for a secure, non-slip grip and comfort, but they are not VDE-rated for electrical insulation. Do not use them on live electrical circuits.
