Variants of pipe wrenches and water pump pliers
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:
The adjustable slip joint is the salient feature of water pump pliers. It enables different opening widths of the gripping jaw - and thus gripping workpieces of different diameters. In order to avoid slipping, the jaws are usually toothed. This in turn means that these teeth, particularly on workpieces made of softer materials such as copper or brass, can leave their mark on the surface.
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.
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.
Siphon connector pliers:
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).
Spring hose clamp pliers:
The hose clamp or spring hose clamp pliers enable the gripping, holding and placing of spring band clamps on automotive hoses thanks to special gripping inserts in the functional jaws.
