For odour trap screw joints, connectors and hoses that have become stuck

The siphon and connector pliers from Knipex are suitable for a range of applications requiring large grip widths and gentle changes of grip that will not damage components. When odour traps need to be opened on kitchen and bathroom fittings, they can be gripped and twisted powerfully in a measured way using the siphon and connector pliers from Knipex. The pliers can unscrew and tighten screw joints on plastic pipes and sensitive connectors, and are also suitable for detaching hoses that have become stuck to supports – e.g. coolant hoses.

Surface contour adapted to the pipe protects screw joints

The gripping jaws here have a different shape to those of water pump pliers, for example. With the siphon and connector pliers, the shape of the gripping jaws has been designed for large pipe diameters. As a result of their round shape, the siphon and connector pliers are used with union nuts on connectors in addition to screw joints of pipes conveying liquids and gas. Such connectors establish an electrical connection that is weather and vibration resistant, e.g. between coaches of rail vehicles. The firmly screwed, replaceable plastic jaws of the Knipex 81 13 250 offer particularly good protection for sensitive surfaces.

Versatile and tough: 25 possible settings and box joint design

With the 25 possible settings, which can be conveniently set to the desired grip width using the fine adjustment push button, the Knipex siphon and connector pliers have a large gripping range of Ø 10 - 75 mm. Thanks to the box joint design and manufacture from oil-hardened chrome vanadium electric steel, the pliers are very tough. The high quality chrome-plating provides good corrosion resistance.
