Description
Knipex 8701400SBA 16″ COBRA XL High-Tech Water Pump Pliers
Heavy-Duty Capacity. Lightweight Precision.
The Knipex 8701400SBA 16" Cobra XL bridges the gap between standard water pump pliers and heavy pipe wrenches. Despite its massive 3-1/2" gripping capacity, it weighs significantly less than a 14" pipe wrench, making it the ideal choice for industrial maintenance, oil and gas, and heavy plumbing.
Featuring 27 adjustment positions, the Cobra XL adapts instantly to the workpiece with a simple press of the patented push-button. Once engaged, the jaws self-lock on pipes and nuts, ensuring that all your muscle power goes into turning the fastener rather than squeezing the handles.
Key Performance Features:
- Massive 3-1/2" Capacity: Grips pipes and hex fasteners that usually require a bulky pipe wrench.
- 27 Fine-Adjustment Positions: Quickly adapts to different workpiece sizes for a comfortable, ergonomic handle width.
- Self-Locking Jaw Geometry: The teeth are designed to "bite" and stay put, preventing slipping and rounding of expensive fasteners.
- Box-Joint Construction: The double-guide design provides extreme stability, preventing the handles from twisting under the high torque loads common in heavy industry.
- Induction Hardened Teeth: Hardened to approx. 61 HRC for long-term wear resistance and a reliable grip for years of professional use.

Frequently Asked Questions
Can the Cobra XL replace a traditional pipe wrench? +
Yes, for many applications. The Cobra XL offers a 3-1/2" capacity and is much lighter than a standard 14" pipe wrench. However, for extremely seized or rusted pipes where you might need to use a "cheater bar," a heavy-duty cast iron pipe wrench may still be preferred.
Does the push-button mechanism get clogged with dirt or grease? +
The push-button adjustment is designed for industrial use. While it can get dirty, it is easily cleaned with a blast of compressed air or a quick wipe. The mechanism is protected within the box joint to minimize exposure to debris.
Is this size (16") too big for standard plumbing? +
The 16" XL is perfect for main water lines, large drain pipes, and commercial fittings. If you are doing residential under-sink work, the 10" or 7-1/4" Cobra models might be more maneuverable in tight cabinets.
