This is a water pump pliers designed for service, maintenance, equipment repair, and automotive access work. Model Number: \u003cstrong\u003e87 51 180\u003c\/strong\u003e. At 7-1\/4 inches long, it gives you the reach advantage of a slim nose without jumping up to a larger, bulkier pliers that is harder to position in confined spaces.\u003c\/p\u003e    \u003cp\u003eWhat separates this Cobra ES from a standard tongue and groove pliers is the jaw geometry. Knipex uses longer, narrower jaws so you can reach deeper past surrounding parts. The front gripping serration adds another layer of usefulness because it helps grab round parts like screws, bolts, and even wire rope near the tip. There is also a groove near the tip for holding nails, pins, and bolts, which makes this tool especially handy when your fingers do not have enough clearance to start or steady a small part.\u003c\/p\u003e    \u003cp\u003eOn the job, the push-button adjustment is a real time-saver. You can set the jaw opening directly on the workpiece instead of stepping through a stiff slip-joint and hoping you land in the right spot. Knipex also gives this model fine adjustment positions for a more precise fit across different sizes. A better fit means less rocking on the part, more control during turns, and less chance of rounding hardware.\u003c\/p\u003e    \u003cp\u003eThe gripping performance is built around practical use, not gimmicks. The tool is self-locking on pipes and nuts, so once it bites, it is less likely to walk off the workpiece. Knipex also calls out firm grip on flat material through three-point contact. In plain terms, this means the jaws are designed to hold both round and flat work more confidently than a general-purpose pliers with a less specialized jaw pattern.\u003c\/p\u003e    \u003cp\u003eBuild quality is what you would expect from Knipex. The pliers are forged from chrome vanadium electric steel and oil-hardened for durability. The box-joint construction matters here because it gives the tool a more stable feel under load and helps the hinge stay aligned over time. Polished jaws and a grey atramentized finish round out the working surfaces, while the non-slip plastic handles keep the grip straightforward and dependable without adding bulk.\u003c\/p\u003e    \u003cp\u003eFrom a jobsite practicality standpoint, this is a smart carry piece for technicians and mechanics who regularly work around harnesses, housings, brackets, and tightly packed assemblies. The slim head and joint construction make it easier to approach a fastener from angles where larger pliers simply will not fit. The pinch guard is a small feature, but it is the kind of detail you appreciate after a long day of repetitive adjustments.\u003c\/p\u003e    \u003cp\u003eIf you do plumbing service, equipment maintenance, automotive work, or general repair, this Knipex water pump pliers earns its place by doing something standard pliers do not do well: reaching in and still holding on. It is not the tool you buy for maximum jaw capacity in open spaces. It is the one you grab when access is the problem and you still need a reliable, controlled grip.\u003c\/p\u003e  \u003c\/div\u003e\u003c\/details\u003e\u003cdetails id=\"product-benefits-1\" class=\"acc\"\u003e  \u003csummary\u003e\u003ch2\u003eReach Into Narrow Access Points\u003c\/h2\u003e\u003c\/summary\u003e  \u003cdiv class=\"acc-body\"\u003e    \u003cdiv class=\"row\"\u003e      \u003cdiv class=\"img\"\u003e        \u003cimg src=\"https:\/\/cdn.anglera.com\/assets\/74d6ed76-fe0d-4d23-a9db-1f8749ca9ef2\/20260526036_2.jpg\" alt=\"Knipex 87 51 180 Cobra ES Water Pump Pliers gripping a narrow metal rod during precision service work in a tight access area\" class=\"tnblock-img\"\u003e      \u003c\/div\u003e      \u003cdiv class=\"copy\"\u003e        \u003cp\u003eThis is where the Cobra ES design pays off.
