Description

Knipex 87 00 100 4″ (100mm) COBRA XS Water Pump Pliers

Small Enough for a Pocket. Tough Enough for the Jobsite.

Don't let the 4-inch size fool you. The Knipex 87 00 100 Cobra® XS is a professional-grade tool engineered to deliver the same legendary performance as its full-sized counterparts. As the smallest member of the Cobra® family, the XS is designed for accessibility in the tightest spaces where standard pliers simply cannot fit.

Despite measuring only 100mm (4"), the Cobra® XS features a self-locking mechanism on pipes and nuts. Once engaged, it stays put—meaning you don't have to squeeze the handles to maintain a grip, allowing you to focus all your energy on turning. It’s the perfect addition to any Every Day Carry (EDC) kit, motorcycle tool roll, or precision maintenance bag.

Why the Cobra® XS is a Must-Have:

  • Ultra-Compact Design: At just 4 inches long, it provides one-handed adjustment and fits into the smallest pockets or pouches.
  • Massive Gripping Capacity: Features a 1" (28mm) gripping capacity, outperforming many pliers twice its size.
  • 11 Adjustment Positions: Fine-tuned adjustment allows for a perfect fit on a wide variety of workpiece sizes.
  • Self-Locking Action: Jaws bite and hold on pipes and nuts, preventing slipping and reducing hand fatigue.
  • Box-Joint Stability: The double-guide design prevents the pliers from twisting or shifting under heavy torque.
  • Textured Grips: The handles are un-dipped but feature a laser-etched texture for a secure grip without adding unnecessary bulk.

Frequently Asked Questions

+ Is this just a novelty or a real tool?
The Cobra XS is a 100% professional tool. It is made from the same forged chrome vanadium steel as the 12-inch version. It is designed for industrial use in extremely confined spaces and is a favorite among mechanics and EDC enthusiasts.
+ Why don't the handles have the red plastic coating?
To keep the profile as slim as possible for pocket carry and tight-access work, Knipex opted for laser-etched textured handles. This provides a non-slip grip without the bulk of plastic dipping.
+ Does it have a push-button adjustment like the larger Cobras?
No. To save space, the Cobra XS uses a clever one-handed sliding adjustment. Simply open the jaws fully and slide them to the desired size. It still provides the same rock-solid locking action once engaged.
+ What is the largest nut it can turn?
The Cobra XS can grip nuts up to 24mm (approx. 15/16"). For its size, it offers the highest gripping capacity-to-length ratio on the market.
