## Long description

The Knipex 87 03 300 tongue-and-groove pliers (Cobra) are high-tech water pump pliers designed for gripping and turning pipes and nuts. With a length of 300 mm and a maximum pipe capacity of 70 mm, these pliers feature an easy one-handed adjustment system: position the upper jaw on the workpiece, press the button and slide the lower jaw into place. Constructed from chrome vanadium electric steel, forged and oil-hardened, they provide durable performance for plumbing and mechanical tasks.
Advantages
Quick push-button adjustment on the workpiece eliminates time-consuming presetting. Fine adjustment allows optimum adaptation to different workpiece sizes and a comfortable handle width. The self-locking mechanism on pipes and nuts prevents slipping and reduces the hand force required. Gripping surfaces have specially hardened teeth (approx. 61 HRC) for high wear resistance and stable gripping. The box-joint design with double guide increases stability, and a reliable catch of the hinge bolt prevents unintentional shifting. A finger guard reduces the risk of pinching.
Suitable for
Gripping and turning pipes up to 70 mm diameter
Working with nuts up to 60 mm across flats
Plumbing installation and repair
Mechanical assembly and maintenance

How to use
Position the upper jaw on the pipe or nut, press the push-button to open the lower jaw and slide it until the jaws engage the workpiece.

After use, wipe the pliers clean and store in a dry place to maintain the hardened gripping surfaces and hinge mechanism.
Usage recommendations
Use the pliers only for their intended purpose — gripping and turning pipes and nuts within the specified size limits. Avoid striking the tool or using it as a hammer. Periodically inspect and lightly lubricate the hinge and keep the gripping teeth clean to preserve performance and service life.
