Stainless Steel V-Band F lange for 4in O.D.

The Stainless Steel V-Band Flange for 4in O.D. is a precision exhaust coupling component engineered for high-performance turbo and supercharger installations. Built for serious enthusiasts and professional tuners, this flange provides a quick-disconnect coupling solution that simplifies component swaps, repairs, and modifications on turbocharged or supercharged engines. Whether you're upgrading intercooler piping, modifying intake manifolds, or installing aftermarket turbo systems, a quality V-band flange eliminates the need for permanent welding or clamp-heavy exhaust connections, allowing flexibility in your build without sacrificing reliability.

Manufactured from premium stainless steel by Vibrant Performance, this V-band flange is designed to handle 4-inch outer diameter tubing and delivers superior corrosion resistance compared to mild steel alternatives. The V-band design relies on a wedge-locking mechanism that creates an exceptionally tight, leak-free seal when the band clamp is torqued—critical for maintaining boost integrity and preventing intercooler or turbo supply line failures under high boost pressure. Stainless construction resists oxidation from sustained heat cycles and moisture exposure, ensuring longevity even in aggressive underhood environments. The flange geometry is precision-engineered to mate seamlessly with standard 4-inch mandrel-bent tubing, guaranteeing concentricity and eliminating costly rework.

This component is ideal for builders working on turbocharged or supercharged platforms where frequent modification cycles or component replacement demands a reusable connection point. Commonly used in intercooler piping systems, charge air cooling lines, and boost supply manifolds, the V-band flange is compatible with any 4-inch O.D. stainless or mild steel tubing. Installation requires a matching V-band clamp (sold separately) and basic hand tools; proper torque specifications ensure optimal sealing without over-tightening. Mechanics and weekend warriors alike appreciate the time savings and flexibility this flange delivers when dialing in air-to-air cooling systems or running multiple turbo configurations on development or race vehicles.
