A band clamp, often referred to as a hose clamp or hose clip, is a mechanical device used to secure and seal hoses, pipes, or other cylindrical objects together. It consists of a flexible band, typically made of metal or plastic, with a tightening mechanism, such as a screw or a worm gear, that allows the band to be tightened around the objects being connected. The band clamp is commonly used in various applications, including plumbing, automotive, and industrial settings. It provides a secure and adjustable means of joining components, preventing leaks, and ensuring a reliable connection between hoses or pipes.
