A T-bolt V band clamp is a type of clamp that is used to secure two sections of tubing together. It is made out of stainless steel and consists of two parts: a band and a T-bolt. The band wraps around the two sections of tubing, and the T-bolt is tightened to secure the band in place. The T-bolt V band clamp is used in a variety of applications, including automotive exhaust systems, industrial piping, and HVAC systems. It is an effective and reliable way to secure two sections of tubing together without the need for welding.
