When the job calls for grip, control, and access in hard-to-reach spaces, the Knipex Cobra ES Water Pump Pliers are built to get in where standard pliers struggle. Designed with longer, narrower jaws and a slim head profile, the Cobra ES series gives professionals the gripping power of the classic Knipex Cobra with an extra-slim design made for service work, maintenance, automotive repair, equipment repair, and general industry applications.

Available in 7 1/4 inch (KNI-87 51 180 SBA) and 10 inch (KNI-87 51 250) sizes, these pliers are ideal for anyone who needs a compact but tough gripping tool that can handle pipes, nuts, bolts, screws, nails, pins, and flat materials with confidence.


Extra-Slim Design for Better Access

The standout feature of the Knipex Cobra ES Pliers is the slim head and joint construction. Compared to standard Cobra pliers, the Cobra ES has longer and more narrow jaws that make it easier to reach into tight areas, around obstructions, and inside cramped workspaces.

This makes them a strong choice for technicians and tradespeople working in mechanical rooms, under dashboards, around equipment, inside cabinets, or anywhere space is limited.


Strong Front Grip for Round Parts

The Cobra ES pliers feature front gripping serrations designed to grab round parts like screws, bolts, and wire rope. This front-grip design adds versatility when you need to hold, pull, or turn parts from the tip of the pliers instead of relying only on the main jaw area.

A groove near the tip also helps hold nails, pins, and bolts securely, giving users more control on small parts that are often difficult to grip with standard pliers.


Secure Hold on Pipes, Nuts, and Flat Material

Like the rest of the Knipex Cobra lineup, the Cobra ES pliers are designed for a strong, reliable grip with less hand effort. They are self-locking on pipes and nuts, which helps prevent slipping off the workpiece while reducing the amount of force needed from the user.

The three-point contact design also helps provide a firm grip on flat material, making these pliers useful beyond plumbing or pipe work. Whether you are grabbing fittings, fasteners, sheet material, or small hardware, the Cobra ES is made to stay controlled in your hand and secure on the workpiece.


Push-Button Adjustment for Fast Setup

The Knipex Cobra ES Water Pump Pliers include push-button adjustment directly on the workpiece. This allows users to quickly dial in the right jaw opening without guessing or wasting time.

The 7 1/4 inch Cobra ES Pliers (KNI-87 51 180 SBA) feature 18 fine adjustment positions, making them compact, precise, and easy to position in tighter spaces. The 10 inch Cobra ES Pliers (KNI-87 51 250) offer 25 fine adjustment positions, giving users more range for larger workpieces while still maintaining the slim ES jaw design.


Built for Professional Durability

Knipex designed the Cobra ES pliers with a box-joint construction for added durability and stability. The hinge bolt is reliably caught to help prevent unintentional shifting during use, while the pinch guard helps protect operators’ fingers from being pinched.

Each pair is forged from high-grade chrome vanadium electric steel and oil-hardened for long-lasting performance on the jobsite, in the shop, or in the service truck.


Knipex Cobra ES 7 1/4 Inch vs. 10 Inch

The 7 1/4 inch Knipex Cobra ES Water Pump Pliers (KNI-87 51 180 SBA) are a great choice when compact size and tight access are the priority. They are easy to carry, easy to position, and ideal for service work where space is limited.

The 10 inch Knipex Cobra ES Water Pump Pliers (KNI-87 51 250) provide more jaw capacity, more adjustment positions, and additional leverage while still offering the slim head and longer narrow jaw design that makes the ES series so useful.

For many professionals, having both sizes in the tool bag gives the best combination of compact access and larger gripping capacity.
