Female V-Band Flange for 3in O.D. Tubing

The Female V-Band Flange for 3in O.D. Tubing is a critical exhaust and intake manifold coupling component designed for high-performance engine builds and custom turbocharger installations. This precision-engineered flange serves as the female half of a V-band clamp assembly, enabling quick-disconnect connections in boost systems where reliability and repeatability matter. Whether you're building a street-strip turbo engine, fabricating custom exhaust headers, or modifying a factory boost setup, this flange eliminates the need for permanent welding or complex bolt patterns.

Manufactured by Vibrant Performance under part number 12491F, this flange is engineered to work with 3-inch outside diameter tubing and features the distinctive V-shaped groove profile that locks into matching V-band clamp hardware. The shallow female profile accepts the male clamp wings, creating a leak-free seal when properly torqued—essential for maintaining boost pressure in turbocharged applications and preventing exhaust leaks that rob horsepower. Constructed from durable materials capable of withstanding thermal cycling and vibration, this component integrates seamlessly into custom piping runs, allowing technicians to build modular, adjustable exhaust and intake systems without permanent modifications to the vehicle's structure.

Engine builders, fabricators, and tuners benefit most from this flange when designing turbo manifolds, intercooler piping, or exhaust systems that require service access or configuration changes. The 3-inch O.D. sizing makes this flange ideal for larger displacement engines and high-airflow boost applications where throttle response and peak power demand oversized plumbing. Installation requires matching it with a corresponding male V-band flange and clamp assembly, ensuring proper alignment and torque specification per manufacturer guidelines for maximum clamping force and repeatability across multiple install-and-remove cycles.
