Pinza regolabile per tubi Knipex 88 03 250 diametro massimo tubi 5 cm

The Knipex 88 03 250 tongue-and-groove pliers are designed for gripping and turning pipes and nuts. With a length of 250 mm and a maximum pipe capacity of 50 mm, these pliers offer robust, precise clamping and high stability for manual plumbing and maintenance tasks. Constructed from chrome vanadium electric steel and multi-stage oil-hardened, the tool is built to resist wear and perform reliably in demanding conditions.

Advantages

Compared with conventional water pump pliers of the same length, the Knipex 88 03 250 provides more output and comfort thanks to a 9-notch adjustment that increases gripping capacity by about 30%. The slim head and joint area improve access to the workpiece, while the self-locking action on pipes and nuts prevents slipping and reduces required hand force. Hardened gripping surfaces with approx. 61 HRC teeth ensure high wear resistance and stable grip. The box-joint design with double guide enhances overall stability, and the robust, dirt-insensitive construction is suitable for outdoor work. A finger guard reduces the risk of pinching.

Suitable for

• Gripping and turning pipes up to 50 mm diameter
• Holding and turning nuts up to approximately 46 mm
• General plumbing, maintenance and repair tasks
• Outdoor and job-site work where dirt resistance is required

How to use

Open the pliers and select the appropriate notch to match the pipe or nut size, then position the jaws on the workpiece. Squeeze the handles to engage the self-locking action and apply torque as needed while maintaining a steady grip. For tighter adjustments, reposition the pliers in a larger or smaller notch and repeat. After use, wipe clean and store in a dry place to preserve the hardened surfaces and joint function.

Recommendations

Use these pliers for mechanical gripping and turning tasks only. Do not use as a hammer or for cutting. Regularly check the jaws and joint for wear; replace the tool if teeth are worn or slipping occurs. Keep away from corrosive chemicals to maintain material hardness and performance.
