What is a V-band clamp primarily used for?

A V-band clamp is primarily used for securely joining two parts together, particularly in applications involving piping systems, exhaust systems, and other assemblies that need a tight connection. The design of the V-band clamp allows for an even distribution of force around the joint, ensuring a secure fit that can also be easily disassembled when necessary. This makes it ideal for situations where components may need to be frequently taken apart or maintained.

The other options do not accurately reflect the primary function of a V-band clamp. While the clamp provides a secure connection, it does not measure the angle of inclination, serve as a buffer, or enhance thermal insulation. Each of those functions pertains to different types of tools or devices designed specifically for those purposes.
