Pliers Knipex Cobra 00 19 55 S5

The Knipex Cobra 00 19 55 S5 pliers are adjustable water pump pliers designed for professional use. Featuring a wide, slip-resistant jaw and a one-handed push-button adjustment mechanism, these pliers allow fast and secure gripping of pipes, fittings, nuts and irregularly shaped objects. With an overall length of 430 mm, a jaw height of 235 mm and a robust construction, the tool provides strong leverage and high durability for repetitive tasks in workshops, maintenance and field service.

Advantages

The tool combines high mechanical strength with precise adjustment: the push-button mechanism enables quick one-handed changes to multiple gripping positions without loss of clamping force. Hardened gripping surfaces ensure reliable bite and reduced slipping on smooth or rounded workpieces. The 430 mm length increases leverage for easier manipulation of tight or rusted connections while the solid build and corrosion-resistant finish extend service life under frequent use.

Suitable for

• Plumbing and pipe installation work
• Automotive repair and maintenance
• Industrial assembly and plant maintenance
• HVAC service and installation
• General mechanical and workshop tasks

Key specifications

• Overall length: 430 mm
• Jaw height: 235 mm
• Weight: 1.59 kg
• One-handed push-button adjustment mechanism for multiple gripping positions
• Slip-resistant, hardened gripping surfaces
• Robust construction suitable for heavy-duty use

How to use

Open the pliers and press the push-button to set the jaws to the required width, then release the button to lock the selected position. Position the jaws around the workpiece and apply controlled pressure on the handles to grip securely. For one-handed adjustment during work, hold the handle and slide the head until the desired bite is obtained; the mechanism will lock automatically. Apply steady force and avoid sudden twisting to maintain tool integrity and achieve a reliable grip.

Usage recommendations

Use the pliers within their mechanical range and avoid applying excessive torque beyond the tool's design. Keep gripping surfaces clean and free of grease for optimal performance. Regularly inspect for wear or damage and store in a dry environment to prevent corrosion. For tasks requiring insulated tools, choose rated insulated pliers rather than uninsulated water pump pliers.
