The KNIPEX Cobra 87 01 180 is a compact, 7-1/4-inch water-pump plier for gripping and turning suitable pipes, nuts and workshop hardware. Its strongest buying argument is the adjustable, self-clamping serrated jaw, not an imaginary promise that it can safely handle every gas fitting or finished surface. The first decision is whether the job needs a firm bite or a non-marring wrench.
KNIPEX lists the model as part number 87 01 180, with 18 push-button adjustment positions and a round-pipe opening up to 1-1/2 inches. The manufacturer also identifies the gripping surface as serrated and explicitly says that the tool is not 1,000-volt insulated. Those facts matter more than broad marketplace claims such as ‘universal shop pliers.’ See KNIPEX’s exact model data.

The problem this tool actually solves
A fixed-opening wrench or poorly adjusted slip-joint plier may be awkward when a maintenance worker moves between several sizes of suitable shop hardware. The Cobra uses a push-button setting and a box joint; KNIPEX says its geometry helps the jaws grip round and hex-shaped components with less hand squeeze. It is a convenient hand tool for fitting and maintenance checks, not a substitute for matching the fastener, fitting material and required torque.
Think about a job where the main difficulty is holding a rough steel part while another component is positioned. A grippy adjustable plier can be appropriate there. Change the workpiece to a brass compression nut, decorative chrome face or a fitting with a prescribed wrench method, and the equation changes. Serrated teeth that hold firmly can also scar the very surface a technician is trying to preserve. That trade-off should be assessed before purchase.
Exact model and package checks
- Manufacturer model: KNIPEX 87 01 180; the Amazon catalog association reviewed for this draft is ASIN B004H36YNI, a ‘SBA’ packaged single-tool offering. Verify the seller’s live listing still matches the exact model before checkout.
- Length: 7-1/4 inches / 180 mm. Do not confuse it with 125, 150, 250 or 300 mm Cobras.
- Mechanism: 18 adjustment positions, push-button setting and serrated hardened gripping teeth. Confirm the replacement model has the same jaw style.
- Capacity: manufacturer lists round-pipe opening up to 1-1/2 inches. That does not certify gripping every fitting within that outer dimension.
- Electrical rating: not insulated for energized circuits. De-energize and follow the applicable electrical safety requirements.
- Selling unit: one tool, not a multicomponent set. Confirm package suffix and seller’s included components.
The product photograph or an Amazon title is not a controlled dimensional drawing. The exact KNIPEX part number and published specifications govern, especially if a shop requires a defined jaw opening or particular finish. The ‘SBA’ suffix refers to a retail package variant in the available marketplace catalog record; it should not be treated as proof of a different base tool without checking the manufacturer or current package label.
Where these pliers are not the answer
Do not use the Cobra as a substitute for a correctly sized flare-nut wrench, manufacturer-specified gas-system service wrench or approved fitting procedure. A wrench that grips a round shape is not automatically suitable for pressure-system assembly. Verify the fitting maker’s torque and seal requirements and isolate pressure or other stored energy under the actual service procedure. WSP’s Find My Part helps identify the equipment and part number before a technician substitutes a similar-looking tool or accessory.
The tool’s noninsulated handles also matter. KNIPEX’s warning is to avoid use on live electrical circuits. Shops should select proper electrical PPE and rated tools where required; merely having red plastic grips is not evidence of a voltage rating. Likewise, eye protection and workholding still matter when a part could slip or release.
Buy/skip decision
Buy this compact Cobra if the work really benefits from a small adjustable serrated-grip plier and the target surfaces can tolerate that contact. Skip it for cosmetic fittings, electrical work on energized equipment, or work that requires a calibrated torque method. If access is limited, check tool reach and clearance against the actual workpiece; nominal tool length alone does not describe every joint position.
