This INGCO pipe wrench is a long-handled tool for gripping and turning round pipe and threaded fittings. The adjustment nut moves the upper jaw to suit the pipe, up to a maximum clamping diameter of 110mm.
The toothed jaws grip the pipe as pressure is applied to the handle. Their angled teeth help the wrench bite as it turns, while the long handle provides leverage for tightening and loosening.
The wrench has a ductile cast iron body and a steel moving jaw. Its nominal 48" size makes it a large tool for work where there is room to use the handle.
