Stainless Steel V-Band F lange for 3.5in O.D.

The Stainless Steel V-Band Flange for 3.5in O.D. is an essential coupling component for high-performance exhaust and intake manifold systems. Built for serious engine builders and turbocharged platform enthusiasts, this V-band flange serves as the precision connection point between turbochargers, intercoolers, exhaust piping, and other 3.5-inch diameter ducting assemblies. Whether you're fabricating a custom turbo kit, upgrading from a bolt-flange design, or assembling a modular exhaust system, the v-band clamp interface eliminates traditional bolt holes and allows tool-free rotational alignment before final clamping.

Manufactured from premium stainless steel by Vibrant Performance, this flange resists thermal cycling, corrosion, and boost-induced vibration that degrades aluminum or mild steel alternatives. The v-band design uses two interlocking semi-circular grooves that create a uniform, repeatable seal across the entire 3.5-inch O.D. circumference when paired with a matching v-band clamp. Stainless construction ensures longevity in underhood environments where exhaust heat and moisture would compromise lesser materials, while the compact profile (6.95 x 10.45 inches overall) integrates seamlessly into tight engine bay layouts without requiring modification to existing support brackets or heat shielding.

This flange is ideal for ls-swap builds, supercharged or turbocharged applications, and custom intake manifold fabrication where repeated assembly and disassembly is common during tuning and dyno testing. Weighing just 0.35 lbs, it adds negligible mass while delivering the structural integrity required for 20+ psi boost environments. Pair it with a matching 3.5-inch v-band clamp and mating flange for complete duct-to-component connections; the stainless steel construction guarantees fade-free performance across multiple heat cycles and full engine operating ranges.
