Design, size and gripping capacity

The 87 01 250 version of the Knipex Cobra measures 250 mm in overall length, which corresponds to 10 inches in the US catalog, and weighs around 0.745 lb according to the US product listing, making it light enough for all-day carry on a belt or in a pouch.US catalog data for 10 inch Cobra

The jaws on this pliers are designed to handle round pipes up to a diameter of 2 inches and hexagonal nuts up to a wrench opening of 46 mm, giving it enough capacity for common residential and light commercial plumbing fittings without moving to a larger tool.Jaw capacity and dimensions

Materials, joint design and adjustment mechanism

The Knipex Cobra Wasserpumpenzange 250mm 87 01 250 is made from chrome vanadium electric steel that is forged and oil-hardened, with serrated gripping surfaces and specially hardened teeth for a stated hardness around 61 HRC, aiming to maintain tooth sharpness under repeated use on steel pipe and fasteners.Technical data and material information

The pliers use a box-joint design with a through-jointed mechanism, and the adjustment is controlled by a push-button that gives 25 discrete positions along the jaw, allowing the user to set the opening size directly on the workpiece with one hand while preventing unintended changes during use.Adjustment positions and mechanism

Handles, ergonomics and safety features

The 87 01 250 configuration comes with non-slip plastic-coated handles rather than multi-component cushions, aiming for a slim profile, and the handle width is listed at about 1 3/4 inches in the US catalog, which gives enough area for a firm grip with work gloves without making the tool bulky.Handle type and width

Knipex specifies self-clamping behavior on pipes and nuts for the Cobra series, meaning the jaw geometry is designed so the teeth dig into the material under load, which helps prevent slipping on round stock and reduces the hand force needed when tightening or loosening fittings, while an integrated pinch guard between the handles is intended to minimize crushing injuries to fingers.Self-clamping and pinch protection

Use cases, comparison and positioning

With its 2-inch pipe capacity and 46 mm wrench opening, the Knipex Cobra Wasserpumpenzange 250mm 87 01 250 sits in the mid-size bracket of the Cobra family, above the 180 mm compact versions and below larger 300 mm or 400 mm models that are designed for bigger fittings, offering a balance between reach and portability for plumbing, HVAC, and general maintenance work.

Compared with Cobra models that use multi-component handle sleeves such as 87 02 250, this 87 01 250 variant keeps simpler plastic-coated handles but retains the same 25-step adjustment and 2-inch pipe capacity, so the main difference lies in grip feel rather than working range or jaw geometry, making this version a practical choice when slim handles are preferred over thicker cushioning.Comparison data for 87 02 250

Context in the hand tool market and verdict

In the US and international hand tool market, a 10-inch water pump pliers with a listed capacity of 2-inch pipe, 25 adjustment positions, and a weight around 0.745 lb positions the Knipex Cobra Wasserpumpenzange 250mm 87 01 250 as a professional-grade option for plumbers, mechanical contractors and serious DIY users who need a compact adjustable pliers that can still tackle typical 1 1/2-inch and 2-inch fittings in residential systems.

The combination of chrome vanadium steel, push-button adjustment, through-joint construction and hardened teeth with about 61 HRC puts the Cobra 250mm 87 01 250 at the more technical end of the water pump pliers category, and for users who already carry larger pipe wrenches for heavy tasks, this model serves as a lighter, more adjustable companion for confined spaces and finishing work where precise jaw positioning and secure self-clamping are crucial.
