Tongue-and-groove pliers Knipex 88 05 300

The Knipex 88 05 300 tongue-and-groove pliers are designed for gripping and turning pipes and nuts. At 300 mm length and 560 g weight, these pliers provide good leverage and comfortable handling. The tool features a slim head and joint area for improved access to the workpiece and a box-joint design for high stability.

Advantages

Nine-position adjustment gives approximately 30% more gripping capacity compared with conventional water pump pliers of the same length. The pliers self-lock on pipes and nuts to prevent slipping and reduce hand force. Gripping surfaces have specially hardened teeth (approx. 61 HRC) for high wear resistance and stable gripping. Robust chrome vanadium electric steel construction is oil-hardened and resistant to dirt, making the tool particularly suitable for outdoor work. An integrated guard helps prevent fingers from being pinched.

Suitable for

• Gripping and turning pipes (max pipe diameter 70 mm)
• Holding and turning nuts (max nut size 60 mm)
• Plumbing and general maintenance tasks
• Outdoor work where a robust, dirt-insensitive tool is required

How to use

Select the appropriate adjustment position for the workpiece by aligning the jaws using the 9-notch adjustment. Place the pliers on the pipe or nut so the hardened teeth engage the surface, then apply steady hand force; the self-locking design reduces the need for continuous grip pressure. Use the slim head to reach confined spaces and the box-joint guidance to maintain stable contact during turning or pulling operations.

Usage recommendations

For long life and consistent performance, keep the joint area clean and lightly lubricated after use. Avoid using the pliers as a hammer or for cutting. Inspect the hardened teeth periodically and replace the tool if teeth are damaged or excessively worn.
