Our range of RS Pro branded VDE insulated adjustable water pump pliers with a box joint are made from Chrome Vanadium Steel and have an insulated grip. Although water pump pliers get their name from being used to tighten the packed glands in water pumps in cars and vans, they can be used for gripping nuts and bolts with large round or square diameters and other irregular shaped objects. Water pump pliers have serrated jaws and long handles for increased leverage.
