What is the exact model and size of these pliers?
This is the KNIPEX Cobra water-pump pliers model 87 01 250, with a nominal length of 10 inches (250 mm). That identifies it separately from other Cobra sizes and variants.
How does the adjustment mechanism work?
A push button moves the box joint through 25 adjustment positions. The pliers can be adjusted directly on the workpiece, with fine positioning intended to maintain a comfortable gripping position for different sizes.
What are the pliers made from?
The body is forged chrome-vanadium electric steel that is hardened through a multi-stage oil-hardening process. The catalogue specification describes the finish as gray atramentized, a surface treatment used on this model.
What size workpieces can the 87 01 250 handle?
The stated capacity is up to 2 inches for pipe and up to 1 3/4 inches for hexagonal workpieces. Its toothed jaws are intended for gripping round pipe and irregular workpieces rather than serving as a general smooth-jaw wrench.
What features help it hold a workpiece securely?
The product uses induction-hardened teeth rated at approximately 61 HRC and a self-locking jaw design. These features are intended to maintain grip on pipes and nuts while reducing the hand force needed during use.
Are replacement parts or jaw protection available?
The exact-model catalogue record identifies replacement adjustment hardware and optional jaw protectors as available accessories or service items. Check current KNIPEX listings for compatibility before ordering parts for model 87 01 250.
