The opening width of the pipe wrench is set by turning the knurled screw. A self-reinforcing lever mechanism is then set in motion by pressure on the upper pliers handle, with which the workpiece automatically clamps. No further pressure has to be applied here for further gripping. Anyone who does not want to leave permanent traces on sensitive materials - for example by using water pump pliers - is well served with the siphon connector pliers. Their designs with gentle plastic jaws and surface contours adapted to the pipe loosen union screw connections on odor traps almost without a trace. These pliers are also built for union fittings that electrical impluses go through (connector plug).

The pliers wrench from KNIPEX is pliers and wrench in one tool. It replaces a whole set of wrenches with continuous gripping in the entire capacity range - metric and imperial! The smooth gripping jaws, which are parallel in any position under load, grip very powerfully with 10 times the hand force. A 45° angled mouthpiece turns a pipe wrench into a so-called corner pipe wrench. It enables use in areas that are difficult to access. More output and comfort compared to conventional water pump pliers of the same length: 9-notch adjustment positioning for 30 % more gripping capacity Water pump pliers, pipe wrenches, pliers wrenches and a number of other special pliers have a number of similar features in terms of structure and mode of operation. For a more precise classification and some essential differences, see the following overview: Water pump pliers: Nevertheless, they protect the workpiece because they grip the surfaces without play and without straining the edges. That makes the pliers wrench particularly suitable for the assembly of parts with sensitive surfaces, e.g. chrome fittings.

Gripping surfaces with special hardened teeth, teeth hardness approx. 61 HRC: high wear resistance and stable gripping The Cobra® XS is of course - like all members of the KNIPEX Cobra® family - self-clamping on pipes and nuts: This prevents slipping on the workpiece and work such as gripping, holding, pressing and bending is much more effortless.

Fine adjustment for optimum adaptation to different sizes of workpieces and a comfortable handle width Next level crimping: Self-adjusting for single wire ferrules up to 16 mm² and twin wire ferrules up to 2 x 10 mm² The Cobra® XS extends the KNIPEX Cobra® family with a compact new member. It is a fully functional high-tech water pump plier, which proves its size especially in tight spaces. By means of fine adjustment directly on the workpiece it offers eleven setting positions, which grip nuts up to 24 mm diameter and other workpieces even up to 28 mm diameter - and all this with a length of only 100 millimetres. Due to its small size, the Cobra® XS can be easily operated with just one hand. Specially hardened jaws with teeth on the inside, hardness approx. 61 HRC: secure Pliering due to high wear resistance

Tools for your industry

Setting is even easier with the KNIPEX SmartGrip®. An intelligent mechanism automatically adjusts the opening width to the workpiece. The pliers are placed on the workpiece, the handles pressed together and they fit and grip securely – if you frequently resort to different workpiece sizes, this will make work easier and is not only valued in the sanitary sector. The bodies of the KNIPEX Cobra® pliers are made of forged chrome vanadium steel and also feature an ideal balance between hardness and toughness by means of a multi-stage hardening process. For a permanently secure "bite" on the workpiece, we also harden the gripping teeth to approx. 61 HRC with high-frequency current. Our efforts in production pay off: Every KNIPEX Cobra® is extremely tough. Water pump pliers are well suited for gripping round and angular parts, even of larger diameters. They play an important role in the area of sanitary installation, but are also used in many other jobs, such as ventilation. The finer the adjustment of a pair of water pump pliers, the more precisely the pliers can be adapted to the size of the workpieces – such as pipes.
