A V-band is a type of mechanical connection used to join two components, typically in exhaust systems or piping. It consists of a circular band that clamps around the joint, providing a secure and leak-proof seal. This design allows for easy assembly and disassembly, making it popular in applications where frequent maintenance is required. V-bands are commonly used in automotive applications, especially in turbochargers and exhaust systems. They offer advantages over traditional flanges, such as reduced weight and improved alignment. The simplicity of the V-band design contributes to its widespread use in various industries, including aerospace and manufacturing.
