Description
Knipex 88 01 250 10″ (250mm) ALLIGATOR Water Pump Pliers Black Metal with Plastic Coated Handles
Unmatched Gripping Power – Set It, Forget It, and Turn
The Knipex 88 01 250 10" Alligator® Pliers are engineered for professionals who need a tool that bites and holds without the constant need for manual squeezing. Featuring a unique self-locking geometry on pipes and nuts, these pliers ensure that once the teeth are engaged, they won't slip—even under heavy loads. You simply apply the turning force, and the Alligator does the rest.
Forged from chrome vanadium heavy-duty steel and oil-hardened, these 250mm pliers feature a box-joint design for ultimate stability. Unlike standard slip-joint pliers, the double guide prevents the tool from twisting or "shifting" when you're applying maximum torque to stubborn fasteners or slick pipes.
Why the Alligator® Series is an Industry Icon:
- Self-Locking Action: Jaws lock onto the workpiece with a rock-solid grip, requiring zero hand strength to maintain the hold.
- 9-Step Adjustment: Precision-machined 9-position adjustment allows you to fit workpieces up to 2" (50mm) in diameter.
- Induction-Hardened Teeth: Hardened to approx. 61 HRC, these teeth stay sharp and aggressive through years of heavy industrial use.
- Box-Joint Stability: The double-guide construction ensures the tool remains rigid and won't flex under pressure.
- Slim Head Design: Reaches into narrow spaces and tight corners where standard wrenches or bulky pliers simply won't fit.

Frequently Asked Questions
+ How does the "Self-Locking" feature help me?
Standard pliers require you to squeeze the handles together while you turn. The Knipex Alligator uses a specialized jaw angle that "bites" into the surface. Once set, it holds itself in place, allowing you to focus 100% of your energy on turning the tool rather than gripping it.
+ Is the Alligator better than the Cobra?
The Alligator is a manual slip-joint tool (9 positions), while the Cobra uses a push-button fine adjustment. Many professionals prefer the Alligator for its simplicity, speed of manual adjustment, and the classic robust feel of the box joint.
+ Will these pliers rust?
The 88 01 250 is treated with a black atramentized finish, which provides excellent resistance to rust and corrosion. For best results in extreme environments, a light coat of oil on the moving parts is recommended.
+ Can I use these on chrome or decorative fittings?
The induction-hardened teeth are very aggressive. On soft, decorative finishes like chrome or brass, they will leave marks. For those applications, we recommend the Knipex Pliers Wrench, which has smooth jaws.
