What do you call a tool used to grip and turn pipes securely?

The tool designed specifically for gripping and turning pipes is the pipe wrench. This tool is characterized by its adjustable jaw, which allows it to securely hold various sizes of cylindrical objects, particularly pipes. The serrated teeth of the wrench provide a strong grip on the pipe, preventing slippage during use. The design and functionality of a pipe wrench make it ideal for plumbing tasks, as it can handle the torque required to tighten or loosen pipe fittings effectively.

Although other tools like slip-joint pliers, channel locks, and combination pliers can also be used for gripping and turning, they do not offer the same level of support and efficiency on large, rounded surfaces like pipes. Slip-joint pliers are more versatile but are less specialized for heavy-duty gripping. Channel locks serve a similar function but are not exclusively designed for pipes. Combination pliers are primarily meant for gripping and cutting wire, making them less effective for plumbing applications compared to a pipe wrench.
