## Long description

The Knipex 81 03 250 siphon pliers are professional-quality pliers designed for gripping and turning union nuts, pipe screw joints and hoses with diameters from 25 to 80 mm. Made from oil‑hardened chrome‑vanadium electric steel and manufactured in Germany, these 250 mm pliers provide a large clamping range with a fine adjustment push button and 25 possible settings to set the required grip width precisely.
Advantages
The pliers have round, pipe‑contour adapted gripping jaws that protect sensitive screw joints and connectors while allowing powerful, measured torque. The box‑joint design and robust chrome‑vanadium construction ensure high durability and resistance to wear. A fine adjustment push button enables quick setting of one of 25 positions for secure, repeatable gripping across a wide range of diameters.
Suitable for
Opening and tightening odour traps and siphons on kitchen and bathroom fittings
Loosening and tightening screw connections on plastic pipes and sensitive connectors
Detaching hoses that have become stuck to supports (e.g., coolant hoses)
Working with union nuts and connectors on pipes conveying liquids and gas

How to use
Select the approximate grip width using the fine adjustment push button and position the round gripping jaws around the union nut, pipe or hose. Apply steady, measured force to rotate or hold the component; the pipe‑contour jaws distribute pressure to minimise damage to sensitive surfaces. For stuck hoses, work progressively along the attachment point while maintaining steady leverage until the hose disengages. After use, clean off any debris and store the pliers in a dry place to preserve the finish.
Usage recommendations
Use the pliers within the specified gripping range (Ø 25–80 mm) and avoid applying excessive impact force on brittle plastic parts. For electrical or pressurised systems, ensure the system is de‑energised and depressurised before working. Regularly inspect the jaws for wear and keep the adjustment mechanism free of dirt to maintain reliable operation.
