A pipe wrench is a type of adjustable tool used primarily for gripping and turning cylindrical objects, especially pipes. It features serrated jaws that provide a strong grip, allowing users to apply significant torque without slipping. The design includes a long handle for leverage, making it easier to loosen or tighten fittings. Typically made of metal, pipe wrenches come in various sizes to accommodate different pipe diameters. They are essential tools for plumbers and are often used in plumbing tasks involving pipes, fittings, and valves. Proper use of a pipe wrench can prevent damage to the materials being worked on.
