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. It is designed for serious engine builders and turbocharged platform enthusiasts, serving as a precision connection point between turbochargers, intercoolers, exhaust piping, and other 3.5-inch diameter ducting assemblies. This flange is ideal for fabricating custom turbo kits, upgrading from a bolt-flange design, or assembling a modular exhaust system.

Manufactured from premium stainless steel, this flange resists thermal cycling, corrosion, and boost-induced vibration that can degrade aluminum or mild steel alternatives. The v-band design utilizes two interlocking semi-circular grooves to create a uniform, repeatable seal across the entire 3.5-inch O.D. circumference when paired with a matching v-band clamp. This ensures a reliable connection that can withstand the rigors of high-performance applications.

This flange is particularly beneficial for LS-swap builds, supercharged or turbocharged applications, and custom intake manifold fabrication where repeated assembly and disassembly is common. Its compact profile integrates seamlessly into tight engine bay layouts without requiring modification to existing support brackets or heat shielding. This makes it a versatile choice for various automotive projects.
