Siphon pliers Knipex 85 01 250

The Knipex 85 01 250 siphon pliers are precision-engineered plumbing pliers for gripping, turning and holding pipes, fittings and nuts. With an overall length of 250 mm and a compact head profile, these pliers allow access in confined spaces while providing secure contact on round and hexagonal parts up to the specified maximum diameters. The tool's robust construction and slip-resistant handles deliver reliable leverage and repeatable performance for maintenance, installation and repair tasks.

Advantages

These siphon pliers combine a long leverage arm and a narrow head to enable high gripping force with controlled movement. Hardened gripping surfaces maintain bite and resist wear during repeated use on metal and plastic pipes. The handles are shaped for ergonomic control and reduce hand fatigue during extended tasks. The design provides quick adjustment and stable clamping on parts of varying sizes without slipping.

Suitable for

• Plumbing and pipe fitting work in tight spaces
• Turning and holding nuts and fittings during installation or removal
• Household repairs and DIY plumbing projects
• Maintenance tasks that require controlled grip on round or hex parts

Key specifications

• Overall length: 250 mm
• Maximum gripping diameter for pipes: 32 mm
• Maximum nut size: 36 mm
• Tool weight: approximately 370 g
• Material: high-strength, hardened tool steel (hardened gripping surfaces)
• Handle type: ergonomically shaped, slip-resistant grips

How to use

Select the appropriate jaw position and place the pliers so the hardened gripping surfaces contact the pipe or nut firmly. Apply steady pressure on the handles to achieve a secure clamp, then rotate or hold the workpiece as required. For tight areas, use the narrow head profile to position the jaws close to adjacent surfaces. Release the clamp by easing the handle pressure and reposition the pliers when needed.

Usage recommendations

Use the pliers within the specified maximum diameters to ensure secure grip and avoid overloading the tool. Regularly clean the gripping surfaces and apply light corrosion protection if used in humid or corrosive environments. Do not use the pliers as a hammer or for cutting. Inspect the tool before use and replace if gripping surfaces or handles show significant wear or damage.
