Water Pump Pliers\u003c\/strong\u003e, model \u003cstrong\u003e87 02 300 SBA\u003c\/strong\u003e, are heavy-duty adjustable pliers built for gripping, turning, and holding pipe, fittings, and large fasteners. This is a \u003cstrong\u003ewater pump pliers\u003c\/strong\u003e tool designed for \u003cstrong\u003egripping pipes and nuts with high holding force\u003c\/strong\u003e. If you need more reach and capacity than a smaller pair of tongue and groove pliers can deliver, this 300 mm Cobra steps up without turning into a bulky specialty tool.\u003c\/p\u003e\n    \u003cp\u003eWhat makes this model matter on the job is the combination of fast adjustment and secure bite. The push-button mechanism lets you set the jaw directly on the workpiece, and the fine adjustment helps dial in the fit so the handle width stays comfortable in hand. Once set, the self-locking action on pipes and nuts reduces slipping and cuts down the squeeze force you need to keep control. That is a real advantage when you are breaking loose tight plumbing connections or holding larger hardware in place.\u003c\/p\u003e\n    \u003cp\u003eCapacity is where this size earns its keep. The 12 in. length gives you solid leverage, while the jaw handles round pipe up to 2-3\/4 in. and nuts up to 60 mm. Knipex also lists 30 adjustment positions, which gives this pair the range to cover a lot of service and install work without needing to switch tools constantly. Compared to a conventional pipe wrench, this style is quicker to reposition and easier to carry for general service work.\u003c\/p\u003e\n    \u003cp\u003eConstruction is straight from the Knipex playbook: chrome vanadium electric steel, forged, then multi-stage oil-hardened. The gripping teeth are specially hardened to about 61 HRC for better wear resistance, which is why these pliers keep biting after a lot of use on metal fittings and hardware. The box-joint design uses a double guide for added stability, and the hinge bolt is retained so it does not shift unintentionally during use.\u003c\/p\u003e\n    \u003cp\u003eJobsite practicality is also well thought out. The multi-component comfort grip helps the tool stay planted in your hand, and the built-in pinch guard gives your fingers a little insurance during adjustment and closing. These are not insulated pliers, so they are meant for mechanical, plumbing, maintenance, and general repair work rather than live electrical work.\u003c\/p\u003e\n    \u003cp\u003eBottom line: this size is a smart pick for plumbers, maintenance techs, mechanics, and serious DIY users who regularly work on larger pipe, valves, unions, and oversize nuts. If a standard 10 in. pair feels undersized for what you do, but a full pipe wrench is more tool than you want to carry all day, the Knipex Cobra 12 in. Water Pump Pliers land right in the sweet spot.\u003c\/p\u003e\n  \u003c\/div\u003e\n\u003c\/details\u003e\n\n\u003cdetails id=\"product-benefits-1\" class=\"acc\"\u003e\n  \u003csummary\u003e\u003ch2\u003eBetter Grip With Less Fight\u003c\/h2\u003e\u003c\/summary\u003e\n  \u003cdiv class=\"acc-body\"\u003e\n    \u003cdiv class=\"row\"\u003e\n      \u003cdiv class=\"img\"\u003e\n        \u003cimg src=\"https:\/\/cdn.anglera.com\/assets\/74d6ed76-fe0d-4d23-a9db-1f8749ca9ef2\/2026052170_5.jpg\" alt=\"Knipex Cobra 12 in.
