Tongue-and-groove pliers Knipex 87 05 250

KNIPEX Cobra high-tech water pump pliers (model 87 05 250) are designed for gripping and turning pipes and nuts. The pliers feature an easy-to-adjust jaw system that lets you set the opening directly on the workpiece by pressing a button and sliding the lower jaw into position. At 250 mm length and a weight of 355 g, they provide good leverage and handling for common plumbing and mechanical tasks.

Advantages

The adjustment button enables quick, precise setting on the workpiece without time-consuming presetting. Fine adjustment allows optimal adaptation to different workpiece sizes and a comfortable handle width. The pliers self-lock on pipes and nuts to prevent slipping and reduce the hand force required. Gripping surfaces have specially hardened teeth (approx. 61 HRC) for high wear resistance and stable gripping. A box-joint design with double guide ensures high stability and reliable catching of the hinge bolt prevents unintentional shifting. A finger guard reduces the risk of pinching. The tool is made of chrome vanadium electric steel, forged and oil-hardened, and has slim two-colour multi-component sleeves without a collar for better handling and easier transport.

• Gripping and turning pipes (max diameter around 50 mm)

Usage recommendations

Use the pliers within the specified pipe and nut size ranges to ensure secure gripping; avoid using the tool as a hammer or for cutting. Keep the tool clean and lightly lubricated at the joint to maintain smooth adjustment and long service life.
