The Vibrant AL V-B Flange Assembly for 3in OD Tubing is a complete assembly that includes two aluminum V-band flanges, one stainless steel V-band clamp, and one Viton O-ring. The flanges are designed to be used with 3in OD tubing for a secure and leak-free connection. The stainless steel V-band clamp ensures a tight seal between the two flanges, and the Viton O-ring creates an additional layer of protection against leaks. This assembly is perfect for high-pressure applications and is designed for easy installation.
